Controls & Indicators
The front panel of the device includes various controls and indicators. The controls and functions on the front panel are labeled as ACC, CALL, SCN, AUX, and TA. The indicators provide information such as:
– An indicator appears while transmitting.
– An indicator appears when trunking is activated.
– An indicator appears while monitoring the selected channel (squelch is off).
– A CALL indicator appears when making a call using Code Squelch or Selective Call and blinks when receiving a Code Squelch call.
– A SCN indicator appears while scanning.
– An AUX indicator appears when the AUX port has been activated or when the Scrambler function has been selected.
– An indicator appears while using the Talk Around function.
– An indicator shows when the selected channel is set as a Priority channel.
– An indicator shows when the selected channel is added to the scanning sequence.
– An indicator appears when a signal is detected on the channel.
The power switch is used to turn the transceiver on or off. Pressing it switches the transceiver on, and holding it for approximately 1 second switches it off.
Installation / Setup
The installation/setup highlights for the equipment include several key points:
1. Pre-Installation Checkout: It is recommended to check the receiver and transmitter operation for proper functioning before installation. This includes testing the radio with all cabling and accessories as they will be connected in the final setup. Important parameters to check are transmitter frequency, deviation, power output, receiver sensitivity, squelch operation, and audio output.
2. Planning the Installation: Inspect the vehicle to determine the mounting locations for the radio antenna and accessories. Plan cable runs to avoid pinching or crushing and ensure the radio installation prevents overheating.
3. Antenna Installation: The preferred location for an antenna is the center of a large, flat conductive area, typically the roof center or trunk lid. Proper grounding of the trunk lid and vehicle chassis using ground straps is advised.
4. Radio Installation: The radio can be mounted using a universal mount bracket. Ensure the mounting surface can support the radio’s weight and allow sufficient space for air cooling. Position the radio for easy access to controls by the vehicle operator.
5. DC Power and Wiring:
– The radio should be installed in negative ground electrical systems only. Reverse polarity will cause the cable fuse to blow.
– Connect the positive power lead directly to the vehicle battery positive terminal and the ground lead to the battery negative terminal.
– If extending the cable, ensure the additional wire can handle the current demand and length.
6. Control Stations: The antenna system selection depends on various factors and should be chosen with the help of a KENWOOD dealer. The control station radio should be located conveniently close to the antenna cable entry point and allow adequate cooling.
7. Transceiver Programming: Requires a personal computer (IBM PC or compatible), programming interface (KPG-46), and programming software (KPG-80D).
These steps are crucial for ensuring the proper installation and operation of the radio equipment.
