SECTION 5 - URC-300 MASTER CONTROLLER
Mounting
The Master Controller can be mounted in any position near the
searchlight that is protected from the weather. Check in advance that
the coax cable from the Point Pad and the wiring harness from the
searchlight can be routed to this location. Mount the Master Controller
with the wires and coax facing down. Use an appropriate fastener for
your mounting location. Use a sealant in fastener holes to prevent
moisture intrusion.

The Master Controller is supplied with an in-line fuse-holder on the
