then coat flat washers, spring washers, nuts
and exposed parts of bolts with silicone
sealant.
Cut a slit in rubber bushing to insert bolts.
Seal washers are not required.

Connecting the Signal Cable
Only the signal cable runs from the display
unit to the scanner unit. In order to minimize
the chance of picking up electrical interfer-
ence, 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 scanner cover by loosening four
scanner bolts, and then fix the stay.
