Operating Modes and Features GRMS Operation: - From GMRS standby mode, press and hold the ( ) button for 2 seconds to turn on power. -Press the MODE button so the Channel number flashes. - Select the desired channel with the Up (10) and Down (11) Buttons. When receiving a call, the signal strength meter appears to indicate incoming received signal strength and the Monitor section of the Transmit/Monitor LED (16) lights green. -Press and hold the PTT button (4) to transmit, then speak into the microphone clearly and slowly. The Transmit section of the Trans- mit/Monitor LED (16) lights red. -Release PTT Button (4) to receive. -Communication can only be accomplished when the channel and CTCSS tone frequency of at least two parties are the same. -The CTC icon will be displayed on the LCD panel 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 GMRS-1200 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. If an FRS only channel (8-14) has been selected, the HI or LO indicator will not be 10 128-6284A 10 of 24 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 these seven 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 (12) once or until the channel number flashes. -Press the Up Button (10) briefly to move to the next higher main channel number. - Press the Down Button (11) 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 Sub-Frequencies. This feature allows you to utilize the coded squelch tones (01. 38) within a main channel. This enables you to communicate with another party on the same main channel using the same subcode. (This filters out unwanted transmissions without the same coded squelch tone). There are 38 CTCSS Sub-channels for each main channel. A different subcode may be selected for each of the 22 channels. To change the CTCSS Sub-channel: -From GMRS/FRS standby mode, press the MODE Button twice; a flashing oF or sub-channel number is displayed, together with the flashing CTC icon. If oF is displayed, press the Up or Down button to enable the CTCSS mode; the CTC icon will also flash on the display with the flashing sub-channel number. -Then press the Up or Down button to select the desired sub-channel for use (01-38). -Press the PTT button momentarily to confirm selection. 11 128-6284A 11 of 24 The CTCSS mode can be turned off by selecting the oF icon as the setting. NOTE: To communicate with other GMRS/FRS units, they must be switched to the same channel and CTCSS subcode. 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 hear...
