NOTICE
Be careful when cutting the hole to mount the speaker. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the speaker after it is mounted.
Before you can mount the speaker, you must select a mounting location.
-
Trim the template and make sure it fits at the mounting location.
-
Secure the template to the mounting surface.
-
Using a 13 mm (1/2 in.) drill bit, drill a hole inside the corner of the line on the template to prepare the mounting surface for cutting.
-
Using a rotary-cutting tool or jigsaw, cut the mounting surface along the inside of the dashed line on the template.
-
Place the speaker in the cutout to test the fit.
-
If necessary, use a file and sandpaper to refine the size of the cutout.
-
After the speaker fits correctly in the cutout, ensure the mounting holes on the speaker line up with the pilot holes on the template.
-
If the mounting holes on the speaker do not line up, mark the new pilot-hole locations.
-
Using a 3 mm (1/8 in.) drill bit, drill the pilot holes.
-
Remove the template from the mounting surface.
-
Install the included mounting gasket on the back of the speaker.
-
Make the necessary wiring connections (Connecting the Active Speaker to the VHF Radio and Handset).
-
Place the speaker in the cutout.
-
Secure the speaker to the mounting surface using the included M4 screws .
-
Snap the screw cover in place.
