Installation / Setup
The installation highlights for the Kenwood VHF FM Transceiver TK-752/759 include several key considerations:
1. Pre-Installation: Unpack the radio and check for accessory items. Ensure all items are present and contact Kenwood if any are missing. Licensing requirements must be met, as federal regulations require a station license for each radio installation.
2. Installation Planning: Inspect the vehicle to determine the best location for mounting the radio antenna and accessories. Plan cable runs to avoid pinching or crushing wiring and ensure the radio is installed to prevent overheating.
3. Antenna Installation: The preferred location for the antenna is the center of a large, flat conductive area, typically the roof center. The trunk lid is also a suitable location, provided it is bonded to the vehicle chassis with ground straps.
4. Radio Mounting: The universal mount bracket allows for various mounting options. 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.
5. DC Power and Wiring: The radio is to 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 battery’s negative terminal. If DC power is controlled by the vehicle ignition switch, use a switching relay.
These steps ensure proper installation and operation of the transceiver.
