[. . . ] General Mobile Radio Service (GMRS) Model : GMRS500SLK Owner's Manual Customer Service 1-800-290-6650 128-7108 1 of 28 Released: 5-28-04 THIS PAGE LEFT BLANK INTENTIONALLY 2 128-7108 2 of 28 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. Important: To maintain compliance with the FCC' s RF exposure guidelines hold the transmitter at least 1 inch (2. 5 centimeters) from your face and speak in a normal voice, with the antenna pointed up and away. [. . . ] - 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 GMRS500SLK has 22 channels (frequencies) indicated by the large digits on the LCD display panel. Channels 8-14 are FRS only channels, while channels 15-22 are assigned GMRS only channels. When operating on FRS only channels (8-14), no power selection is possible or is displayed. Using low power, the unit will have a lower transmit range, but battery life will be increased. To access the transmitter power selection function: - From GMRS/FRS standby mode (shared channels 1-7 or GMRS only channel (15-22) selected), press the MODE Button three times until the power HI or LO indication appears with a flashing Pr indication on the display. - Press the Up or Down button to toggle between the High and Low selections. - Press the PTT button momentarily to confirm selection. 13 128-7108 13 of 28 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 Up or Down button to select the 1 or 2 VOX level sensitivity. - The icon only appears when the VOX mode is enabled. Dual Watch Mode This feature allows you to monitor two channels at the same time. While in dual watch mode, the unit will continuously monitor both the primary and dual watch channel. Received signals will be played for 5 seconds, then the unit will resume scanning the two channels. Pressing the PTT button during a received transmission will set the unit to transmit on the same channel. Pressing the PTT button when no signal is received will set the unit to transmit on the primary channel. To set the Dual Watch Mode: - From GMRS/FRS standby mode, press the MODE button 5 times (4 times for FRS); appears flashing on the display. - To enable the dual watch mode, press the Up or Down button; the dual watch channel number will flash and start to increase or decrease as the Up or Down button is pressed. - To select a subcode for the dual watch channel, press the MODE button while the selected dual watch channel is flashing. Then use the Up and Down buttons to select the desired CTCSS subcode. 14 128-7108 14 of 28 - 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. [. . . ] · Turn your transceiver off wherever posted notices restrict the use of radios or cellular telephones. Facilities such as hospitals may use equipment that is sensitive to RF energy. 19 128-7108 19 of 28 · 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 No transmission while pressing the PTT Button Possible cause Weak batteries Incorrect battery polarity Correction Charge or replace batteries Install the batteries following the directions in paragraph Installing the Batteries.
