Connecting the signal cable
Only the signal cable runs from the display unit (power supply unit in case of 1954C) 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 bolts, and then fix the stay.
2. Unfasten the cable gland assembly (plate, gasket, flat washer).
3. Pass the signal cable with connector through the bottom of the antenna unit chassis.
Pass the cable through the gland assembly as shown below.
