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. [. . . ] - Press and hold the PTT button (3) to transmit, then speak into themicrophone clearly and slowly. The Transmit Signal indicator ) appears on the display. ( NOTE: When the transmission is not available with beep tone, the battery is low; recharge the unit. When the battery icon is flashing, transmitting is not possible; recharge the unit. - 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 GMRS762CH 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. 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. - Press the PTT button momentarily to confirm selection. 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: 14 128-7627 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. [. . . ] Its output is designed to meet the legal limits set by the FCC. · Do not use this device or change its batteries in potentially explosive atmospheres as sparks in such areas could result in an explosion. · 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. 20 128-7627 20 of 28 · Turn your transceiver off on board aircraft when requested to do so. [. . . ]
