SQUELCH: Reduces background noise when there is no incoming signal. 4. RF GAIN: Improves reception in strong signal areas. 5. MIC GAIN: Adjusts microphone sensitivity. 6. S/RF CAL SWR Knob: Selects function of meter. 7. LSB AM USB Knob: Selects mode. 8. CLARIFIER Knob: Fine tunes the SSB receiving signals. 9.
Grant LT.qxd 3/31/99 10:03 AM Page 3 18. Channel Display: Displays current channel selection. 19. ANT.: Connects antenna cable to transceiver. To prevent acoustic feedback, separate the microphone from the speaker when operating the PA at high output levels. 20. PA. SP.: Connects external 8-ohm 4-watt Public Address speaker. When the external speaker is plugged in, the internal speaker is off. 21. EXT. SP.: Connects optional 8-ohm 4-watt speaker to remotely monitor receiver. 22.
Grant LT.qxd 3/31/99 10:03 AM Page 4 Installation MOUNTING THE RADIO BRACKET Plan the location of the transceiver and microphone bracket before beginning installation. 1. Select a location that is convenient for operating the radio, but does not interfere with the driver or passenger. 2. Remove the mounting bracket from radio and use it as a template for marking the location of the mounting screws. 3. Drill the necessary holes and secure the mounting bracket in place using mounting screws.
Grant LT.qxd 3/31/99 10:03 AM Page 5 Connecting the Antenna Connect the CB antenna plug to the Antenna Connector on the rear panel. (For more information on antenna installation, please refer to the instruction guide that came with your antenna.) CB Antenna Tips ● A vertically polarized quarter-wavelength whip antenna provides the most reliable operation and greatest range. The shorter loaded type whip antennas are more attractive and compact than the larger full quarterwavelength whip.
Grant LT.qxd 3/31/99 10:03 AM Page 6 To Receive Be sure that the power source, antenna, and microphone are properly connected before proceeding. 1. Turn unit ON and set VOLUME Control to a comfortable level. 2. Select CHANNEL. 3. Set switch to NB/ANL. Dynamic Squelch Control automatically sets Squelch to the optimal level for stronger transmission and signal clarity. To scan for weaker signals, turn Dynamic Squelch Control off and perform the following steps: 4a.
Grant LT.qxd 3/31/99 10:03 AM Page 7 5. Adjust RF GAIN knob to optimize reception in strong signal areas. 6. Adjust CLARIFIER knob to reduce or eliminate adjacent channel interference. 7. Set the meter selector to S/RF. To Transmit 1. Select a channel. 2. Adjust MIC GAIN. 3. When the channel is clear, press the microphone PTT switch and speak. If the channel is busy, do not transmit until it becomes clear.
Grant LT.qxd 3/31/99 10:03 AM Page 8 Multi-Function Meter SWR Meter: Measures SWR (standing wave ratio) of antenna. Use to check antenna system or to adjust your antenna to the proper length. To measure SWR: 1. Set the Mode Selector to the AM position. 2. Set the Meter Selector to the CAL position. 3. Press and hold the microphone PTT Switch. (Transmit) 4. Calibrate the meter using the SWR CAL Control. (Adjust the needle to the ▼ mark.
Grant LT.qxd 3/31/99 10:03 AM Page 9 RF Meter: Measures RF Output Power for transmitter. To use the RF Meter, position the Meter Selector at S/RF. Press the microphone PTT Switch to read your transmitting RF power. S-Meter: Measures incoming signal strength. To use the S-meter, position the Meter Selector at S/RF. The meter swings to indicate signal strength. i.e. S 3, S 5, S 7 . . . Preventive Maintenance Every six months: 1. Check the Standing Wave Ratio (SWR). 2.
Grant LT.qxd 3/31/99 10:03 AM Page 10 Troubleshooting Problem Unit does not power on. No reception. Poor reception. No transmission. Low transmission. Suggestion Check the ignition key position. Check all connections to the DC power cord as well as the fuse inside the holder. If fuse is out, replace with a 4-ampere, 3AG fuse only. Check the vehicle electrical system. Make sure the microphone is properly connected. Set the CB/PA Switch to CB. Adjust the squelch and volume.
