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 other brands of batteries, as batteries may burst causing personal injury and damage to the product. When recharging Lithiumion(Li-ion) batteries with the AUDIOVOX charger, use only 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.

- Release PTT Button (4) to receive. - 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.
party on the same main channel using the same subcode. (This filters out 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.
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 2 represents high sensitivity, and should be used in a relatively quiet surrounding. A VOX sensitivity of 1 represents low sensitivity and should be used in a noisy environment. To set the VOX sensitivity level: - Press the MODE button 4 times (3 times for FRS) until the Vo icon appears on the display accompanied by the flashing numeral 1 or 2.
- 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 5 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 3 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 3, 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.

To search the FM station : - Press the Up Button (10) briefly to move to the next higher FM station in 200kHz steps. - Press the Down Button (11) briefly to move to the next lower FM station in 200kHz steps. NOTE: Even though the FM radio mode is active, you can still transmit and receive the GMRS/FRS signal. To inhibit the GMRS/FRS receive signal mode, press and hold the the M button; the monitor icon will appear on the display. To exit this function press and hold the M button again.
NOTES FOR GOOD COMMUNICATION 1 . The GMRS500SLK 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 GMRS500SLK 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.
