[. . . ] General Mobile Radio Service (GMRS) Model : GMRS-1535 Owner's Manual A EMG AUDIO OX Customer Service 1-800-290-6650 CAUTIONS NEVER ATTEMPT TO CHARGE ALKALINE OR DRY CELL BATTERIES. WHEN RECHARGING, USE ONLY AUDIOVOX APPROVED RECHARGEABLE BATTERIES AND CHARGER. USE OF THE CHARGER WITH OTHER BATTERIES WILL CAUSE DAMAGE TO YOUR GMRS-1535 RADIO TRANSCEIVER. AVOID PLACING THE GMRS-1535 RADIO TRANSCEIVER FOR PROLONGED PERIODS OF TIME IN DIRECT SUNLIGHT OR TEMPERATURES BELOW -4° F (-20° C) OR ABOVE 140 ° F (60° C). [. . . ] This feature allows you to utilize the coded squelch tones (00­38) 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). To change the CTCSS Sub-channel, - From GMRS standby mode, press the Mode Button twice; a flashing oF or sub-channel number is displayed. If oF is displayed, press the Up or Down button to enable the CTCSS mode; the CTC icon will appear steady on the display with the flashing sub-channel number. 11 - Then press the Up or Down button to select the desired sub-channel for use. The CTCSS mode can be turned off by selecting the oF icon as the setting. NOTE: To communicate with other GMRS units, they must be switched to the same channel and CTCSS subcode. 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. To activate the tone code (CTCSS) scan mode, - From GMRS standby mode, press the MODE button twice to select the CTCSS function. 13 - Press the SCAN button; the radio will begin scanning for all tone codes (00­38) relative to the current main channel selection. - To disable the tone code scan, press the SCAN button again, and the radio will return to normal operation. 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 standby mode, press the MODE button 5 times; the DW icon flashes on the display. - To enable the dual watch mode, press the Up or Down button; the dual watch channel number will flash and start to increment up or down as the Up or Down button is pressed. - Press the MODE button again to select the CTCSS function and select the CTCSS code if desired for the dual watch channel just selected. - Press the Power On/Off button to confirm selection of the dual watch channel. The display will now alternate between the primary channel and the dual watch channel just selected. Momentarily press the SCAN button to exit the dual watch mode. 14 Key Tone This feature allows the transceiver to sound a confirmation tone whenever the following keys are pressed: Monitor (M) Button, Up/Down Buttons, MODE Button, SCAN Button, or the EMG Button. [. . . ] Facilities such as hospitals may use equipment that is sensitive to RF energy. · 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. If the air-bag deploys, it could propel the transceiver like a projectile causing bodily injury. 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. 20 Troubleshooting (Cont. ) Problem Weak or no signal received Possible cause 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 Correction 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 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.
