Lowrance 3500c 操作ガイド

Drill a 1-inch (25.4 mm) hole in the dash for the power and antenna 
cables. The best location for this hole is immediately under the gimbal 
bracket location. This way, the bracket can be installed so that it covers 
the hole, holds the cables in position and results in a neat installation. 
Some customers, however, prefer to mount the bracket to the side of the 
cable hole — it's a matter of personal preference.

After drilling the hole, pass the antenna connector up through the hole 
from under the dash. Pass the power cable's bare-wire end down 
though the hole from the top. 

If you wish, you can fill in the hole around the cables with a good marine 
caulking compound. (Some marine dealers stock cable hole covers to con-
ceal 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 
GlobalMap 3500C. 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, thus 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.
