Frequency Selection Guide

Radio frequencies used for wireless communication in most countries including the United States are under strict control and regulations. These regulations specify which devises can be used at what frequency and tend to limit interference within the frequency bands.

To ensure consistent reliable frequency availability and to minimize the interference that might occur the user can choose frequency bands between 470 and 489 MHZ or 514 and 542 MHZ.

For the users convenience, and to help prevent interference, a number of preset frequency groups and channels have been programed into the system. For the use of a single system these preset frequencies usually do not need to be changed. When using multiple receivers and transmitters each system must use a separate and different channel. Grouping the receivers and then using separate channels on the transmitters will provide the best frequency use and distribution.

When using up to 4 units (max of8 channels) in the same frequency range, the wireless microphone system does not require an antenna combiner under normal conditions.
If using S to 7 units (10 to 14 channels) the use of an approved antenna combiner is highly recommended. The official antenna distribution partner of Airwave Technologies is RF Venue. They are without question, the leaders of antenna distribution.

Receiver Set Up

To Set Frequency and Channel: 

Press button for 2 seconds to unlock then press button until “GR”(group) flashes. Press or to select the group. Figure. 1
Press until “CH”(Channel) is flashing. Press or to select channel. Figure 2
Press  until “SQL“(squelch) flashes. Press or to select a squelch start with three stall regulation. Figure 3
Press until “TX SET” and ”RF” are flashing. Press or to adjust the transmitter power level as necessary. Figure 4
Press until “TX SET and “GAIN” are flashing. Press or to adjust microphone gain as necessary. Figure 5 

To Set Receiver Volume Control:
This unti has an electronic volume control system.
To adjust the system press the button for two seconds to unlock then release. Press or button to control receiver output volume. Figure 8.

Setting Automatic Frequency

Handheld Transmitter: Turn off the power switch of the handheld transmitter, and then open the battery cylinder. Point its IR window to the IR window of the receiver. Press the button of the receiver and turn on the power switch of the handheld transmitter.
Bodypack Transmitter: Point the IR window of the bodypack transmitter to the IR window of the receiver. Press the button of the receiver and the button of the bodypack.
Whenever the button of the receiver is pressed, synchronizing signal will be transmitted continuously for 25 sec and on the screen flashes. When the infrared receiving circuit is enabled, On the handheld transmitter will flash and the entire display screen of the bodypack transmitter will flash along with the infrared transmission indicator lamp.
When establishing infrared connection between the receiver and the transmitter, the distance between them should not exceed 2 feet. When more than one system is used, only IP window of one trdr?5mitt£’r Should be pointed to the receiver for each infrared Connection.

Important Safety Instructions

• Transmitter and antenna should remain in line of sight for best signal reception.
• Do not place the receiver in close proximity to a metal surface or near any digital device.
• Receiver should be placed 3‘ off the ground and have space surrounding to ventilate.
• Ventilation holes should not be covered.
• Two-way radios can interfere with any audio transmission. Insure the transmitter and receiver are far from these devices to eliminate potential sources of interference.
• Receiver should not be placed in direct sunlight and should be kept away from any water sources or open flame.
• Nominal operating temperature is -5° C – +50° C (23° F – 122° F)
