Important Notice
Caution
This product is intended to be used on DOGS ONLY.
E-Collar Technologies, Inc. is not responsible for any misuse of this product including damages from dog bites and lost items. Seek an evaluation by the professional trainer before use on aggressive dogs. It is not uncommon for aggressive dogs to associate the stimulation with the handler and take action against the handler. Sometimes dogs put under e-collar pressure during a fight can exhibit redirected aggression and become more aggressive.
The use of high levels of stimulation should only be used as a last resort and in life-threatening situations.
To prevent giving stimulation to your dog by accident, keep the stimulation level below 5 while not in use.
The range of the 300/302 may vary according to terrain, weather conditions, foliage, and power lines as well as radio transmissions from other devices.

- Collar Receiver Battery Charging
- Receptacle and Rubber Cover
The indicator light will turn solid red during charge cycles and turn green if it is fully charged. (approximately 2 hours)
Special Not About Battery Care:
Your e-collar is outfitted with Li-Polymer batteries which require specific care to assure longevity. It is best not to let the battery be fully discharged and if it does recharge immediately or irreversible damage may occur. Keep the units away from extreme heat and cold temperatures.
TURNING YOUR E-COLLAR ON/OFF
- To turn the Collar Receiver On or Off :
Place the small red dot on the Transmitter against the small red dot on the Collar Receiver.
- To turn the Transmitter On or Off :
Press the “L” button for more than 2 seconds.
If the Transmitter is turned on, a short press of the “L” button will activate the tracking light of the collar receiver. Press and hold for 2 seconds to turn Transmitter off.
- Holding the Transmitter
To obtain the maximum range hold the transmitter like the torch on the Statue of Liberty. Keep the antenna away from your body or fingers at all times, touching the antenna will greatly reduce the range.
CORRECTLY FITTING THE COLLAR

The collar should be adjusted to allow the “contact points” to have direct contact with the skin. You should be able to fit a couple of fingers between the collar strap and your dog’s skin. Too tight poses the risk of skin irritation and discomfort. Too loose and the contact points will not be able to administer the stimulation reliably and can cause skin irritation due to chafing. Short hair breeds may need the 3/8″ microprobes offered as an accessory item, contact customer service for details. The optimal position for the collar receiver is on either side of the dog’s windpipe. If the factory installed 5/8” contact points are not making good contact due to thick fur, see page 24 for changing contact point.
IMPORTANT NOTICE
To prevent the occurrence of skin irritations the Collar Receiver should never be worn for more than 12 hours per day. Should your dog experience skin irritations from over exposure to the contact points remove the collar receiver unit immediately and stop using your
e-collar until all skin irritations are completely healed. Antibiotic ointment will aid in the healing process. Some dog breeds have extra thick fur or extra short fur that requires special contact points. Please contact our customer service or visit www.ecollar.com for more information.

- Momentary Stimulation
Sends a single pulse of stimulation at the set level when you press the stimulation button. - Continuous Stimulation
Sends pulses of stimulation for as long as the button is pressed, timing out after 10 seconds (this is a safety feature designed to prevent accidental over-stimulation of your dog). The stimulation can be increased or decreased while the button is being pressed. - Tapping Sensation
Vibration is specifically designed to distract your dog, great for deaf dogs and stimulating sensitive dogs. - Tone/Stimulation (Pavlovian Stimulation)
After 1.2 seconds of tone, the collar will send continuous stimulation for as long as the button is pressed. Release before 1.2 seconds for tone only. - Stimulation Button S (Black)
- Sends momentary or continuous stimulation to the collar receiver based on the state of Momentary/Continuous Mode.
- Stimulation Button S (Red)
- Sends momentary or continuous boosted stimulation.
- If the stimulation level is 10, boosted stimulation sends [10 + boost level ]
- The default value of the boosted level is 5, it can be adjusted to any value between 1 and 60. Smaller and more sensitive breeds should use levels 1 through 20, larger more stubborn breeds may need more of a boost, maximum boost is 60.
- Boosting Stimulation in Combo Mode
Momentary Boosting is accomplished by first sending a momentary stimulation pulse “S (Black)” to the dog and then pressing the “S (Red)” button without releasing “S (Black)” button. (PLEASE PRACTICE) Continuous Boosting is accomplished by first administering continuous stimulation “S (Red)” to the dog and then pressing the “S (Black)” button without releasing the “S (Red)” button. - Tapping Sensation (Vibration) or Tone/Stimulation “T”
Sends Tapping Sensation or Tone/Stimulation to the collar receiver.
(Default setting is tapping sensation).
To toggle between tapping sensation and tone stimulation, press the “L” and “T” buttons simultaneously when the intensity level is “0”.- A single beep and “A” icon indicate 1.2 S of Tone followed by the Stimulation setting.
- Double beeps and the “T” icon indicate Tapping Sensation (Vibration).
Tapping Sensation Pavlovian Tone/Stimulation
- Light Button “L” (ON/OFF Center Button on Back)
When pressed less than a 1/2 second, it will turn on the night tracking light, pressing it again the light will enter the solid mode and pressing one more time turns the light off. Flashing -> Solid -> OFF Great for locating your dog after dark. (PLEASE PRACTICE)
HOW TO FIND THE PROPER STIMULATION LEVEL
Rotating clockwise increases the stimulation level, and rotating counter-clockwise lowers the stimulation level.
It is highly recommended that the user practice changing levels and modes before putting the collar receiver on a dog.
Setting the correct stimulation level for your dog is very important. To set your “conditioning” stimulation level, correctly put the collar receiver on your dog (see page 9 for instructions). Let him/her get used to the collar receiver for a couple of hours.
While watching your dog, turn the level to “0” and press the continuous stimulation button. Slowly turn the stimulation up at a rate of approximately 2-3 levels per second. When your dog first perceives the stimulation, usually between 5 and 20, release the button. This is your “conditioning” stimulation level. You may need to increase the
“conditioning” level a few levels to get your dog to respond at first, some dogs are more stubborn and need more stimulation. The boosted level is typically 5 to 20 levels higher than the “conditioning” level.
LOCK/UNLOCK THE STIMULATION LEVEL
How to Lock/Unlock the Stimulation Level
Set the desired stimulation level and then push down on the top of the stimulation dial until you see “1D” light up on the top portion of the LCD display. Flashing “1D” indicates unlocked stimulation and Solid “1D” indicates locked stimulation.
If the stimulation level doesn’t change when you rotate the stimulation knob, you have successfully locked the stimulation level.
To unlock the stimulation level simply press the stimulation knob again and hold it for 1 second until the “1D” icon flashes.
HOW TO SET THE BOOST
Boosted Stimulation adds the set boost level to the stimulation level, great for those situations when your dog doesn’t respond to the working level. Determining the Boosted stimulation level is a little more difficult than stimulation level setting due to the wide differences in temperaments and stimulation tolerance among the many breeds of dogs. On average, it is normally 5 to 20 levels higher than the “Conditioning” level. It is important to have it set high enough to get the desired response from your dog.
- Change the mode to Momentary Mode. (Press M/C button until “M” is displayed)
- Change the intensity level to “0”.
- Press S(Black) button for more than 5 seconds.
- The intensity level will change from “0” to a flashing “1”.
- Rotate the dial to the desired boost level (1 to 60).
- Press S(Black) button again to save and exit the boost level changing mode.

TESTING YOUR E-COLLAR
If you need to check your unit, hold the test light against the contact points on the collar receiver. This test will let you know that the collar receiver is generating the proper sensation to the dog, it should brighten in a smooth fashion as the dial is turned up.
Some people find it easier to hold the collar receiver in the palm of their hand and slowly turn the stimulation up using the continuous mode, typical humans feel it between 8 and 25 depending on the dryness of their hands.
Feel free to contact us if you have need help, at 1-855-326-5527.
REPLACING THE CONTACT POINTS
The standard 5/8” contact points are used for most dogs. Thicker fur breeds require longer 3/4” contact points. Replace the 5/8” contact points by following the instructions below using the enclosed contact point tool.
- Loosen both contact points by rotating the contact point counter-clockwise using the contact point tool.

- Install the 3/4” contact points onto the bolt and tighten the contact points by rotating them clockwise with the contact point tool.
* For short-haired breeds such as boxers, dachshund, pit bulls, etc, and thick fur breeds please visit our website or contact us to inquire about special contact points for your dog.
TRAINING TIP
IMPORTANT TRAINING TIPS
E-Collars can be used to reinforce commands your dog already knows or as a learning sensation when paired with leash pressure. It is not a replacement for basic leash obedience training, but a tool to allow you to better communicate with your dog. For best results, use the least amount of stimulation required to get the attention of your dog. A calm and consistent approach to training will always produce better long term results. It is highly recommended that aggressive dogs be taken to a professional trainer for evaluation before e-collar use. There are many different e-collar training techniques recommended by a variety of professional trainers. We believe you, the owner of the dog, can best determine the most successful technique for your dog. We recommend first time users to emerse themselves in learning about the proper techniques or seek a professional e-collar trainer.
The technique used in the initial introduction of the e-collar is very important to the success of e-collar training. Search E-Collar Technologies on youtube and subscribe to our channel, new training videos are posted weekly. Also “Like” and subscribe to our Facebook page to receive more training advice and connect with other e-collar users.
Good Luck with your training from your friends at E-Collar Technologies
TROUBLESHOOTING
My Receiver / Transmitter is not turning on.
Make sure the collar receiver is fully charged. The Collar receiver light should turn green when the battery is connected to the charger.
My Receiver is not responding.
Check Receiver’s indicator light is blinking green and Transmitter LCD is on. Check to make sure the collar receiver’s indicator light is red when the stimulation button is pressed
Try pairing/syncing the transmitter to the receiver. (Page 17)
The receiver doesn’t seem to provide stimulation to the dog.
Remove Contact points from Receiver. Connect the Test Light to the receiver and test for stimulation. If the test light is blinking, the receiver is providing stimulation.
Max the range of devices been decreased?
Check Transmitter’s battery condition. The working range decreases when the battery level is low.
Keep your fingers from touching the antenna. See the bottom of page 8 for the proper technique to maximize range.

FAQS
Another really important thing to do with this collar is make sure the dog does NOT equate this collar with the stimulation. It is suggested to put it on in the morning and take it off before bed, not just put it on before/after walks or events with them especially when first training them with it. When I was training my dog I had a specific whistle which gave him about 3 seconds to respond before the vibration went off. Now when I make that sound he responds immediately without the need to send a signal. My hope is that in his head I was warning him of the sensation prior to it happening, not the one causing it. I still use his collar after a year but have only used the vibration a handful of times this last year—depending on the dog and trainer the collar might only need to be used temporarily.
Yes, although described as a “mini” this e-collar will work for most dogs if used correctly. You might need to shave a small patch for the collar to make contact. If you haven’t done so, please watch the Leesburg videos on using the e-collar, particularly the one by Micheal Ellis. The dog needs to learn behavior that stops the stimulation. If introduced correctly, i.e., the dog learns that he has control of the stimulation, the e-collar works for most dogs.
I have used this collar on several large dogs including several Golden Retrievers and Labradors with success.
Peace and Be Well
Yes! My dog is around 25 lbs and I cut about 10 inches off of the adjustable collar-almost enough to make another collar. I have only had to use the correction levels up to 26, so there are plenty of levels higher for those bigger or more stubborn dogs. I’ve been working with a dog trainer to help me give the correction at the right time and used a leash for the first 3 weeks. Using the leash helped me guide my dog into the preferred behavior immediately after the correction so she was not confused as to why she was just corrected. It has completely transformed my dog’s behavior and I’m very pleased with the product. If this is your fist electronic collar please make sure you get some tips or work with a trainer. If you do not guide your dog into the behavior you want you will get a very anxious dog afraid to move or do anything. That was my only complaint with this product-in needed some tips for newbies like me. You will love your “new” dog!
Looks like K9 400 collar might be the best. I have a boxer with short hair so the contacts that came with the mini educator were fine. I think if you have the right fit, it would work as well. Burrow it down to the skin level, obviously not too tight. The K9 400 model is for training tactical dogs like German Shepherds
This is not a shock collar. This collar is actually shock resistant. It is similar to a TENS unit to where it creates basically a muscle spasm. No reputable trainer will recommend a shock collar, as they are painful for dogs.
The 300 has a 1/2 mile range, the 800 has a 1-mile range and has a larger/stronger receiver
It has one charging cord with 3 connection points on the same cord.
We do not ship internationally.
As long as you hang on to your invoice.
Only bought the single collar, but have another brand and whatever the setting is on is what both dogs will feel. Assuming Educator collars would be the same?
The antenna has a male threaded screw. Maybe a 1/4-20 thread? Whatever it is, it’s beefy enough to hold the 3/8″ antenna.
Yes, the ET-302 comes with 2 collars.
Just press and hold the dial down for a few seconds. It’s a safety feature, meant to help you not accidentally bump the dial up or down. Press and hold again to lock it down on the number you want.
The manufacturer offers a full 2-year warranty on the e-collars.
No it’s not normal. It may be his fur. They have longer prongs you can order. (Different lengths for different fur). I’d also make sure it’s working properly take it off your dog and test it on the palm of your hand. Grip it tight and start with a low number.
Nope.
Yes it does. it works great on my 10lbs dog and it would probably be fine on an even smaller dog.
Yes.
