Installation / Setup
The installation highlights for the TK-690H(B) KENWOOD radio include several key considerations:
1. Mounting: The radio can be mounted using a universal mount bracket, which allows for various mounting positions. Ensure the mounting surface can support the radio’s weight and provide enough space for air cooling. The radio should be positioned close enough to the vehicle operator for easy access to controls.
2. Licensing: A station license is required for each radio installation, and the licensee must ensure transmitter power, frequency, and deviation comply with the station license limits. Only licensed technicians can perform transmitter adjustments.
3. Pre-Installation Checkout: It is recommended to check the receiver and transmitter for proper operation before installation. This includes testing the radio with all cabling and accessories as they will be in the final setup.
4. DC Power and Wiring: The radio should only be installed in negative ground electrical systems. Connect the positive power lead directly to the vehicle battery’s positive terminal. If the power cable needs to be extended, ensure the additional wire can handle the current and length.
5. Installation Planning: Plan the installation by inspecting the vehicle to determine the mounting locations for the radio antenna and accessories. Protect cables from pinching or crushing and ensure the installation prevents overheating.
6. Antenna: The preferred antenna location is the center of a large, flat conductive area, typically the roof center.
7. Control Stations: Select a convenient location for the control station radio close to the antenna cable entry and ensure adequate airflow for cooling around the radio and power supply.
