[. . . ] GMRS/Weather Model: GMRS-2000 General Mobile Radio Service Base Station With NOAA Weather Alert Owner'sManual Customer Service/Service 1-800-290-6650 CAUTION 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-2000 TRANSCEIVER. OTHER TYPES OF BATTERIES MAY BURST CAUSING PERSONAL INJURY. [. . . ] The GMRS-2000 has 15 channels (frequencies) indicated by the large digits on the LCD display panel. Channels 1-7 are also compatible with the Family Radio Service (FRS) communication channels, thereby allowing 2-way communication with other FRS units. Before transmitting on the selected channel, press the Monitor (L/MON) Button (2) to check the activity on that channel. If there is activity on the selected channel, wait until the channel is clear. To change the GMRS channel: - From GMRS standby mode, press the Up Button ( ) briefly to move to the next higher main channel number. - Press the Down Button ( ) briefly to move to the next lower main channel number. VOX Selection This option enables you to have hands-free conversation. 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 standby mode, press the VOX button; the VOX icon appears steady on the display. 10 - At the right side of the unit, select the desired VOX sensitivity level by setting the VOX switch to LO, MID or HI position. - Momentarily press the VOX button to discontinue the VOX mode. NOTE: When the unit is transmitting in the VOX mode, no functions on the unit will operate. To regain control of the functions, it may be necessary to reduce ambient noises. Scan Operation This feature allows you to monitor all channels and tone codes (CTCSS) automatically for valid signals. When the unit is in the scan mode, a received signal will be audible for 10 seconds before the unit resumes channel scanning. To remain on a particular channel, press the SCAN or the PTT button. The weather alert function will be disabled in when the unit is in the scan mode. - Momentarily press the ALT button again to exit the weather alert function. GMRS Menu Functions Refer to the illustration on following page for a graphic representation of the various menus. Continuous Tone Coded Squelch System (CTCSS) Mode (SubChannel) Selection The Coded Tone Controlled Squelch System (CTCSS) consists of 38 Sub-Frequencies. This feature allows you to utilize the coded squelch tones (01-38) within each main channel (1-15). This enables you to communicate with another party on the same main channel using the same subcode. (The CTCSS filters out unwanted transmissions without the same coded squelch tone. ) Each of the 15 GMRS channels may be set independently. Tune the unit to the desired channel before setting the CTCSS code. To change the CTCSS Sub-channel: - From the GMRS standby mode, press the MODE button once; a flashing CTC icon and sub-channel number is displayed. - Press the CHANNEL Up or Down button to select the desired subchannel for use. The CTC icon will continue flashing with the subchannel number. [. . . ] Facilities such as hospitals may use equipment that is sensitive to RF energy. 18 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 Charge light flashes 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. Batteries are not installed and Install Audiovox approved CHARGE switch (2) in the batteries or set the ON position CHARGE switch to OFF. 19 Technical Specifications: General Frequency Range: GMRS Weather Privacy Codes Dimensions (W x H x D) (Without Antenna) Power Supply Power Source AC/DC Adapter Input: 120 Vac Output: 12 Vdc, 1. 5 Amp Battery Backup Operating Time Battery Backup Receiver Useable Sensitivity Maximum Audio Output Power Modulation Distortion Transmitter Maximum RF Output Power: High Low Range Maximum Deviation Modulation Distortion 2. 0 Watt 0. 5 Watt maximum Up to 5 miles +/- 2. 5 kHz < 5% (1 kHz 70%) 20 >-119 dBm > 300 mW (8 Ohm ) < 5% (1 kHz 70%) Rechargeable, AA (5), 6. 0 VDC, 1300 mA 18 hours - NiMH (Transmit: Receive: Standby) (5: 5: 90 ratio) Refer to chart on next page Refer to chart on next page 38 for each main channel 6. 7 in x 7. 0 in x 2. 6 in 170. 0 mm x 177. 0 mm x 66 mm This transceiver complies with FCC regulations for use in the United States of America.
