2.3 POWER CABLE INSTALLATION

It is recommended that both wires of the power cable be connected directly to the vehicle battery. Connection of either wire to other points may result in increased interference from the vehicle’s electrical system. If noise is still a problem with both wires connected to the battery, a noise filter should be used.

NOTE: With LTR-Net models, do not connect the power cable to a switched power source such as the ignition switch or a relay. Always use the front panel power switch or the ignition sense input described in Section 2.4.3 to switch power. When power is switched externally with LTR-Net models, the de-registration message cannot be sent and the current user settings are not saved.
