Installation / Setup
The installation of the Kenwood UHF FM Transceiver TK-880/H involves several key considerations:
1. 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 wiring and ensure the radio is installed to prevent overheating.
2. Antenna: The preferred location for an antenna is the center of a large, flat conductive area, typically the roof center. If mounted on the trunk lid, bond it to the vehicle chassis using ground straps.
3. Radio Mounting: Use the universal mount bracket to mount the radio securely. 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.
4. DC Power and Wiring: The radio should be installed in negative ground electrical systems only. Connect the positive power lead directly to the vehicle battery’s positive terminal and the ground lead to the negative terminal. If controlling DC power with the vehicle ignition switch, use a switching relay for the positive power lead.
5. Pre-Installation Considerations: Unpack the radio and check for all accessory items. Ensure transmitter power, frequency, and deviation comply with the station license. Transmitter adjustments should be performed by a licensed technician.
6. Installation Planning for Control Stations: Select a location close to the antenna cable entry point and ensure adequate cooling for the radio and power supply.
These steps ensure proper installation and operation of the transceiver, adhering to safety and regulatory requirements.
