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.
