When receiving a call, the signal strength meter appears to indicate incoming received signal strength and the Monitor section of the Transmit/Monitor LED(9) lights green. - Press and hold the PTT button (4) to transmit, then speak into the microphone clearly and slowly. - 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/FRS units, both transmitting and receiving party must be on the same frequency. To communicate with other GMRS 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. 12 Transmit Power Selection Mode (GMRS Channels Only) This feature permits selection of the transmitting power level to high or low. Using low power, the unit will have a lower transmit range, but battery life will be increased. NOTE: You will find that for the majority of your needs, the low-power setting will provide adequate communications on all channels; there should seldom be any need to use high power, except in situations where you need absolute maximum range. However, we do recommend that you not change this setting unless it proves to be necessary in your particular situation. To access the transmitter power selection function: - From GMRS standby mode, press the Function (F) Button 3 times until the Po indication appears with a flashing Hi or Lo indica tion on the display. - Press the Up or Down button to toggle between the High and Low selections. The display will indicate the current setting in standby mode. VOX Selection Mode This option enables you to have hands-free conversation. When using the internal microphone/speaker or external microphone/headset (purchased separately), your voice or the signal is detected and the radio transmits and receives automatically. Your voice or nearby sound is detected and the radio transmits without the need to press the PTT button. To set radio for VOX operation: - From GMRS/FRS standby mode, press the Function (F) button four times until the VOX icon appears flashing on the display. - Press the Up or Down button to select VOX On (if oF appears flashing) and the 1-5 VOX level sensitivity. 13 - Momentarily press the PTT or PWR button to confirm the VOX selection. VOX can be turned off by selecting oF as the setting. 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 heard for 5 seconds, then the unit will resume scanning the two channels.

If the air-bag deploys, it could propel the transceiver like a projectile causing bodily injury. 19 Troubleshooting Problem No transmission while pressing the PTT Button Possible cause Weak batteries Incorrect battery polarity Correction Charge or replace batteries Install the batteries following the directions in paragraph Installing the Batteries. Charge or replace batteries Adjust the transceiver's settings to match those settings of the target transceiver Increase volume level Release PTT Button Change to a different channel Avoid operating in or near large buildings or vehicles Charge or replace batteries Weak or no signal received Weak batteries Channel and privacy code not set the same as target transceiver Volume level too low PTT Button inadvertently depressed Excessive radio interference on a particular channel Obstruction of radio signal Unit beeps, but will not function when turned on Reception of unwanted signals Batteries extremely discharged CTCSS privacy mode not on Interference from electronic devices such as computers or TVs Turn on the CTCSS privacy mode and set code number to match the setting of the target transceiver.
