RBRC Information
As part of our commitment to protect the environment and conserve natural resources, Uniden voluntarily participates in an RBRC® industry program to collect and recycle used Ni-MH batteries within the US. Please call 1-800-8-BATTERY for information on Ni-MH battery recycling in your area. (RBRC® is a registered trade ark of the Rechargeable Battery Recycling Corporation.).
MAINTENANCE
To be safe and sure:
- Never open your radio’s case.
- Never change or replace anything in your radioexcept the batteries.
Your radio might cause TV or radio interference even when it is operating properly. To determine whether your radio is causing interference, turn it off. If the interference goes away, your radio is causing it. Try to eliminate the interference by moving your radio away from the receiver. If you cannot eliminate the interference, the FCC requires that you stop using the radio.
Hazardous Environments
Do not operate the radio in hazardous environments. An explosion or fire may result. Do not operate the radio near unshielded electrical blasting caps.
Under certain conditions, radios can interfere with blasting operations and may cause an explosion. Turn your radio OFF to prevent accidental transmission when in a blasting area or in areas posted: “Turn off two-way radio.” Construction crews often use remote-control RF devices to set off explosives.
Care and Safety
To clean the radio, use a soft cloth dampened with water. Do not use cleaners or solvents because they can harm the body of the unit and leak inside, causing permanent damage. Use a dry, lint-free cloth to clean the battery contacts. Do not submerge the unit in water. If the unit gets wet, turn it off and remove the batteries immediately.
Dry the battery compartment with a soft cloth to minimize potential water damage. Leave the battery compartment cover off overnight to ensure complete drying. Do not use the radio until the unit is completely dry.
WARNING! Read this information before using the radio. In August 1996 the Federal Communications Commission (FCC) of the United States with its action in Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radiofrequency electromagnetic energy emitted by FCC-regulated transmitters.
Those guidelines are consistent with the safety standard previously set by both U.S. and international standards bodies. The design of the radio complies with the FCC guidelines and these international standards.
Never allow children to operate the radio without adult supervision and the knowledge of the following guidelines.
FCC RF EXPOSURE INFORMATION
WARNING! It is up to the user to properly operate this radio transmitter to ensure safe operation. Please adhere to the following:
Use only the supplied or approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the radio, or result in a violation of FCC regulations.
Do not use the radio with a damaged antenna. If a damaged antenna comes into contact with the skin, a minor burn may result. Please contact your local dealer for a replacement antenna.
Body-Worn Operation
This device was tested for typical body-worn operations using the supplied belt clip.
To maintain compliance with FCC RF exposure requirements, body-worn operations are restricted to the supplied belt clip.
For hand-held operation, the radio should be held 1 inch from the user’s face. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements and should be avoided.
For more information about RF exposure, please visit the FCC website at www.fcc.gov.

FAQS
Yes, it does have this ability.
You can use AA rechargeable NiMH batteries.
You can use 3 AA rechargeable NiMH batteries. That is what the unit comes with as well.
Neither the radio nor the charging cradle are waterproof.
There is a lip on the clip, you pull it towards yourself and push up.
The maximum range for a walkie-talkie is usually around 5 miles, but some designs can go all the way to 36 miles. However, this range differs greatly depending on your surroundings, and the maximum distance listed usually refers to when the devices are transmitting between two high points.
Press and hold (MENU) to turn the radio on. A channel number will appear on the display. 2. Press and hold (MENU) to turn the radio off.
In summary, any two or more brands of walkie-talkie CAN be made to work with each other, provided that they are on the same frequency band, AND provided that they are or can be programmed to use the same frequencies.
Push-to-talk (PTT) button: The PTT button on the side of the radio has two main functions: – Press and hold down to initiate and call and talk; release the PTT button to listen.
The Uniden GMR2059-2CK is a powerful two-way radio delivering up to 20 miles of range in ideal conditions (up to 2 miles in urban conditions). This model supports 22 channels, each with 142 privacy codes. The GMR-2059-2CK also features Uniden’s voice scrambling feature, which helps keep your conversations private.
Two-way radios are able to communicate with each other when they are on the same radio frequency. For this reason, there is no limit to the number of walkie-talkies that can connect together, providing they are sharing a frequency.
To put it simply, for maximum power, use channels 1-7 or 15-22. Most consumer radios support two or more power modes. To get the most range, be sure that you are using high power mode on the channels that allow it. Lower power modes will not use all of your radio’s possible output power and will reduce range.
To synchronize both radios, ensure that the private code numbers on the radios are set to the same number after which you can set both walkie-talkies to the same channel. Most radios have 22 channels. To figure out what channel number your radio is on, you check the display and then save the channel.
Because you don’t have to dial a number each time you want to transmit, walkie-talkies are quick and easy to use. And best of all, they don’t rely on finicky cell phone signals. The handsets transmit directly to each other, so they still work when cell networks fail during natural disasters or power outages.
A radio button, AKA an “option button” is a UI element every web/mobile/desktop developer is familiar with. It allows choosing only one option out of a set. Radio buttons are named after the actual physical buttons used on old radios to switch between frequencies and preset stations.
Boaters often mount radios with the legal limit of 25 watts and, depending on the height of the antenna, can reach communication distances as far as 60 miles or more. Everyone on the water should have a marine radio, however, not everyone needs that much power while enjoying water activities.
Atmospheric noise from thunderstorms can interfere with HF radio. Given that many users of HF radio – for military communications or humanitarian needs, for example – operate in extreme environments, there may be more than just rain to contend with.
Press the “Scan” button to put the handheld into scanning mode and press “Manual” to enter manual programming mode. Your scanner will have a number of available channels that can be programmed. Enter the channel number you wish to use and press “Manual” again.
Perfectly suited for all boating and marine applications, the MHS050 is a 2.5-watt Waterproof* VHF Marine Radio. Equipped with a table-top drop-in charger allowing you to conveniently charge your unit this compact two-way radio is certified to meet the world standard JIS8 waterproof level.
