Pass the power cable's bare-wire end down though the hole from the
top. If you want, you can fill in the hole around the cables with a good
marine sealant compound. (Some marine dealers stock cable hole cov-
ers to conceal the opening.)
No matter what type of installation you prefer, be sure to leave enough
slack in the cables to allow tilting or swiveling the unit. If you choose to
fill in the hole, be sure to position the cables against the rear edge of
the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the
rear edge of the hole. Then, slide the bracket over the hole and butt the
rear of the bracket base firmly against the cables, pinning them in
place against the side of the hole. Finally, fasten the bracket to the
dash. Attach the unit to the gimbal bracket using the supplied gimbal
knobs and washers.
In-Dash Installation
You can mount the unit in the dash with an optional FM-5 In-Dash
Adapter Kit. The kit includes mounting hardware, a template for cut-
ting the hole and an instruction sheet, part 988-0147-43.
