[. . . ] R THIS PAGE LEFT BLANK INTENTIONALLY 2 128-7521 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. [. . . ] 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. If an FRS only channel (8-14) has been selected, 12 128-7521 12 of 28 the HI or LO indicator will not be displayed on the LCD panel; otherwise, for channels 1-7 (GMRS/FRS) and 15-22 (GMRS only), the HI or LO indicator will be displayed. Communication with Audiovox FRS and compatible units is possible on the shared and FRS only channels. Before transmitting on the selected channel, press the Monitor (M) Button (2) to check the activity on that channel. If there is activity on the selected channel, change to another channel that is clear. To change the channel: - From GMRS/FRS standby mode, press the MODE button (6) once or until the channel number flashes. - Press the Up Button (15) briefly to move to the next higher main channel number. - Press the Down Button (13) briefly to move to the next lower main channel number. - Press the PTT button momentarily to confirm selection. CTCSS Mode (Sub-Channel) Selection The Coded Tone Controlled Squelch System (CTCSS) provides 38 SubFrequencies. 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: 14 128-7521 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. - Press the PTT button momentarily to confirm the VOX selection. - 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. [. . . ] · 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. 20 128-7521 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.
