[. . . ] General Mobile Radio Service (GMRS) Model : GMRS-7000 Owner's Owner 's Manual Manual EMG A HI LO CTC ID OUT OF RANGE © 2002 Audiovox Electronics Corp. , Hauppauge, NY 11788 Customer Service 1-800-290-6650 Released: 3-28-02. CAUTION ONLY USE THE AUDIOVOX-APPROVED RECHARGER WHEN RECHARGING THE NICKEL METAL HYDRIDE (NiMH) BATTERY PACK. USE ONLY THE AUDIOVOX RECHARGEABLE BATTERY PACK APPROVED FOR THIS UNIT. DO NOT USE THE AUDIOVOX CHARGER WITH OTHER BRANDS OF BATTERIES. AVOID PLACING THE GMRS-7000 RADIO TRANSCEIVER FOR PROLONGED PERIODS OF TIME IN DIRECT SUNLIGHT OR TEMPERATURES BELOW -4° F (-20° C) OR ABOVE 140 ° F (60° C). [. . . ] 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 standby mode, press the MODE button once so 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. 11 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 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). - Momentarily press the PTT button to confirm the VOX selection; the VOX icon will appear steady on the LCD display. A VOX sensitivity of 5 is the most sensitive, and should be used in a relatively quiet surrounding. A VOX sensitivity of 1 is the least sensitive and should be used in a noisy surrounding. 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 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 five times; dc appears on the display with the flashing DW icon. If the dual watch mode 13 is off, the oF icon will also appear flashing. - 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. NOTE: while selecting the dual watch channel, a long tone will sound when the channel selected for dual watch mode is the same as the primary channel when the key tone feature is enabled. - Press the PTT 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. Roger Beep Tone The Roger Beep is a tone which is automatically transmitted whenever the PTT button is released. This tone alerts the receiving party that the transmission has been terminated intentionally. [. . . ] Facilities such as hospitals may use equipment that is sensitive to RF energy. 19 · 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 battery pack Correction Charge or replace battery pack Weak or no signal received Weak battery pack 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 Charge or replace battery 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 obstructions Charge or replace battery pack 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. Unit beeps, but will not function when turned on Reception of unwanted signals Battery pack extremely discharged CTCSS privacy mode not on Interference from electronic devices such as computers or TVs 20 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 52 mm x 117 mm x 36 mm Power Supply Power Source Operating Time (Transmit: Receive: Standby) (5: 5: 90 ratio) Ni-MH rechargeable, Battery Pack, 6. 0 VDC, 900 mAh 9 hours Low Power 7 hours High Power Receiver Useable Sensitivity Maximum Audio Output Power Modulation Distortion >-119 dBm > 0. 3 Watt maximum (8 Ohm ) < 5% (1 kHz 70%) Transmitter RF Output Power Maximum Deviation Modulation Distortion 3. 0 Watt maximum (high power) 1. 0 Watt maximum (low power) +/- 2. 5 kHz < 5% (1 kHz 70%) 21 This transceiver complies with FCC regulations for use in the United States of America.
