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.
WARNINGS: Battery Care Never attempt to charge alkaline or dry cell batteries, as batteries may burst causing personal injury and damage to the product. If rechargeable batteries are used, such as Nickel Metal Hydride (NiMH), use only the supplied Audiovox-approved rechargeable batteries. Use of the Audiovox charger (also supplied) with other brands of batteries is not recommended, as battery charging times will vary with different brands.

WARNING: Do not attempt to recharge Alkaline batteries. 2. Audiovox Rechargeable Ni-MH Batteries - (Rechargeable NiMH batteries and Charging Adapter included). Use only Audiovox approved rechargeable batteries and charging equipment when charging batteries internal to the unit. NOTE: To extend battery life, avoid overcharging the batteries 3.
The following guidelines will improve performance and provide longer operating times for the GMRS2572: 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.

- Communication can only be accomplished when the channel and CTCSS tone frequency of at least two parties are the same. - The CTCSS small segment display will appear next to the main frequency channel on the display if the CTCSS tone frequency function is enabled. Channel Selection In order to communicate with other GMRS units, both transmitting and receiving party must be on the same frequency. The GMRS2572CH has 22 channels (frequencies) indicated by the large digits on the LCD display panel.
unwanted transmissions without the same coded squelch tone). There are 38 CTCSS sub-channels for each main channel. A different subcode may be selected for each of the 22 channels. To change the CTCSS sub-channel: - From GMRS/FRS standby mode, press the MODE Button twice; a flashing oF or sub-channel number is displayed. If oF is displayed, press the Up or Down button to enable the CTCSS mode. - Then press the Up or Down button to select the desired sub-channel for use (01-38).
VOX Sensitivity Level Selection This selection enables you to set the sensitivity level to compensate for ambient noise in your immediate area. A VOX sensitivity of 3 is the most sensitive, and should be used in a relatively quiet surrounding. A VOX sensitivity of 1 is the least sensitive and should be used in a noisy surrounding.
- Press the PTT button momentarily to confirm selection of the dual watch channel. The display will now alternate between the primary channel and the dual watch channel just selected. NOTE: Pressing the PTT button during dual watch mode will transmit on the primary channel and suspend dual watch operation for 20 seconds. Dual watch mode will then resume. - Momentarily press the SCAN button to exit the dual watch mode.
Call Ringer Selection Mode The transceiver provides 10 user-selectable call ringer melodies to alert you to an incoming call. To select your favorite call ringer melody: - From GMRS/FRS standby mode, press the MODE Button 8 times (7 times for FRS). CA will appear on the display, together with a flashing number between 1 and 10, and an appropriate call ring. - Press the Up or Down Button to preview and hear the 3 available call melodies. - Press the PTT button momentarily to confirm selection.
Auto Key Lock Selection Mode This feature prevents accidental channel change to the preferred settings of the unit.

To select a weather channel, the unit must be in the weather channel mode. Press and hold the MODE/WB button for at least 3 seconds; the weather alert icon ( ) will appear, together with a channel number in the band. Momentarily press the MODE/WB button (12) once; the channel number flashes.

Remove batteries from plastic wrapper. 2. Insert batteries into each radio, observing polarity. 3. Place each radio in the charger base (charging LEDs should be on) 4. Charge for 6-7 hours.
NOTES FOR GOOD COMMUNICATION 1 . The GMRS2572CH 22 channels are shared on a ‘take turns’ basis. This means other groups may be talking on any of the channels. A common code of ethics/courtesy is to switch to another vacant channel and not to attempt to talk over someone who is already using the channel you first selected. 2. The GMRS2572CH has been designed to maximize performance and improve transmission range in the field.
• Turn your transceiver off on board aircraft when requested to do so. • Do not place your radio in front of a vehicle’s air-bag. If the air-bag deploys, it could propel the transceiver like a projectile causing bodily injury. Troubleshooting Problem Possible cause Correction No transmission while pressing the PTT Button Weak batteries Incorrect battery polarity Charge or replace batteries Install the batteries following the directions in paragraph Installing the Batteries.
