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. [. . . ] - 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 GMRS600SCH has 22 channels (frequencies) indicated by the large digits on the LCD display panel. To communicate with other GMRS/FRS units that do not have subcodes, switch your unit to the same channel with the subcode set to oF. The CTCSS subcodes do not prevent others from hearing your transmission. This will only allow you to ignore all traffic on a given channel not using the same subcode. Transmit Power Selection Mode This feature permits selection of the transmitting power level to high or low. 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. 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: 14 128-7348 14 of 28 - 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. 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. [. . . ] · 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. 20 128-7348 20 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.
