[. . . ] 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. OTHER TYPES OF BATTERIES MAY BURST CAUSING PERSONAL INJURY. [. . . ] - Press the Down Button (11) briefly to move to the next lower main channel number. CTCSS Mode (Sub-Channel) Selection Coded Tone Controlled Squelch System (CTCSS) with 38 Sub-Frequencies. 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). There are 38 CTCSS Sub-channels for each main channel. A different subcode may be selected for each of the 15 channels. 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. - Press the Power On/Off button momentarily to confirm selection. 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. If the dual watch mode is off, the oF icon will also appear flashing. [. . . ] · 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. Turn the devices off or move farther away from them. 21 Technical Specifications: General Frequency Range GMRS (15 Channels) Channel Spacing Weather Band (7 Channels) Canadian Maritime (3 Channels) Privacy Codes Dimensions (W x H x D) (Without Antenna) 462. 5500 - 462. 7250 MHz 12. 5 KHz 162. 4000 - 162. 5500 MHz 161. 6500, 161. 7750, 163. 2750 MHz 38 for each main channel 2. 10 in x 3. 86 in x 1. 10 in 53. 4 mm x 98 mm x 28 mm Alkaline Batteries, AAA (4), 6 VDC Ni-MH rechargeable, AAA (4), 4. 8 VDC, 650 mAh 30 hours Low Power 14 hours High Power Power Supply Power Source Operating Time (Transmit: Receive: Standby) (5: 5: 90 ratio) (Based on alkaline batteries) Receiver Useable Sensitivity Maximum Audio Output Power Modulation Distortion >-119 dBm > 0. 3 Watt maximum (8 Ohm ) < 5% (1 kHz 70%) 1. 8 Watt maximum (high power) 0. 5 Watt maximum (low power) +/- 2. 5 kHz < 5% (1 kHz 70%) Transmitter RF Output Power Maximum Deviation Modulation Distortion 22 This transceiver complies with FCC regulations for use in the United States of America.
