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 (8-15), 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 Po 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 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. 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 VOX icon and the numeral 1, 2 or 3. - Press the Up or Down button to select the 1-3 VOX level sensitivity. - Press the PTT button momentarily to confirm the VOX selection. - The VOX icon will disappear from the display unless 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 14 128-7032A 14 of 28
