Installation / Setup
The installation setup for the transceivers includes the following highlights:
1. Mounting Bracket Installation:
– Consider ease of operation and safety when selecting the location for the mounting bracket in your vehicle.
– Use the flat washers and self-tapping screws supplied with the transceiver to install the bracket.
– Attach the transceiver loosely using the 4 SEMS screws provided.
– Align the grooves in the bracket with the transceiver’s screws and slide the transceiver to the rear.
– Adjust the viewing angle of the bracket to the desired position.
– Hold the transceiver in place and tighten the 4 SEMS screws using the supplied wrench.
2. Power Requirements:
– The power requirement is 13.8 VDC. Never attempt connection to a 24 VDC source.
3. Clearance and Ventilation:
– Ensure good ventilation by not placing anything on top of the cabinet and allowing at least 15 cm (6 inches) of space behind the unit.
4. Environmental Considerations:
– Do not place the unit in areas of excessive dust, high humidity, or on unstable surfaces.
– Avoid placing the transceiver where the heat sink (rear panel) might come in contact with plastic or vinyl surfaces.
