CAUTION SAFETY INFORMATION Your wireless hand-held portable transceiver contains a low power transmitter. When the PTT button is pushed (or the VOX mode is enabled) it sends out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices.

Installing the batteries: Battery installation is made more convenient when the carry clip is rotated either left or right to the upside-down position, or is removed completely. Simply rotate the clip in either direction to the vertical position. Be careful not to use excessive force. To remove the clip, press down on the the release tab and pull the clip straight out from the radio body.
The following guidelines will improve performance and provide longer operating times for the GMRS121-2: 1. Do not mix old and new batteries. 2. The use of alkaline-type batteries is recommended to provide the longest operating time. 3. Do not mix alkaline, standard (carbon-zinc) or rechargeable batteries. 4. If the unit is not to be used for an extended period of time, remove the batteries. Old or leaking batteries can cause damage to the unit and will void the warranty.
Controls: Power On-Off/SCAN Button (10) Press and hold the PWR on/off button for at least 2 seconds. You will hear a confirming melody to indicate the unit is on. To turn the unit off, press and hold the button for at least 2 seconds. Adjusting the Volume (6, 7) ) to With the unit powered on, press the Up Channel/Volume button ( increase volume and the Down Channel/Volume button ( ) to decrease volume. The display will indicate the current volume level ( V ) followed by the number (1-7).
Up Channel/Volume Button (6) In the standby mode, pressing this button will increment the listening volume. When in function edit mode this button will be used to adjust the unit’s settings. Down Channel/Volume Button (7) In the standby mode, pressing this button will decrement the listening volume. When in function edit mode this button will be used to adjust the unit’s settings. MODE Button (8) This button is used to select various feature settings in the GMRS and FRS modes.
Channel Selection In order to communicate with other GMRS/FRS units, both the transmitting and receiving party must be on the same frequency. The GMRS121-2 has 22 channels (frequencies) indicated by the large digits on the LCD display panel. Channels 1 through 7 are the shared GMRS/FRS channels. Channels 8-14 are FRS only channels, while channels 15-22 are assigned GMRS only channels. Communication with Audiovox GMRS/FRS and compatible units is possible on these 22 channels.
VOX Selection Mode This option enables you to have hands-free conversation. When using the internal microphone/speaker, your voice or the signal is detected and the radio transmits and receives automatically. Your voice or nearby sound is detected and the radio transmits without the need to press the PTT button. To set the radio for VOX operation: - From GMRS/FRS standby mode, press and hold the MODE button for 2 seconds, or until the VOX icon appears on the display.
To enable the channel scan mode: - From GMRS/FRS standby mode, momentarily press the Power On/Off Button; SCAN will appear on the LCD display. - The radio will automatically display each channel (1-22) in ascending order to find an active main channel. - When the unit doesn’t find any signals and you want to transmit, press the PTT Button to return to primary channel operation. The transceiver will automatically resume scanning approximately 10 seconds after the communication is completed.
Warning • Do not operate the transceiver unless you are licensed to do so. • Remove the batteries from the transceiver if it is not expected to be used for long periods. This will eliminate the possibility of chemicals leaking from the batteries and corroding the transceiver. • Avoid exposing the transceiver to water or extremes of temperature. • Do not use this device in or near a mining facility, which uses remotely triggered explosives or in areas labeled “Blasting Area”.
Troubleshooting Problem Possible cause Correction No transmission while pressing the PTT Button Weak batteries Incorrect battery polarity Replace batteries Install the batteries using the directions for correct battery installation.
