Connecting the signal cable

Only the signal cable runs from the processor unit (1953C-BB: power supply unit) to the antenna unit. In order to minimize the chance of picking up electrical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also, avoid running the cable in parallel with power cables. Pass the cable through the hole and apply sealing compound around the hole for waterproofing.

1. Open the antenna cover by loosening four scanner bolts, and then fix the stay.
