Important:
Overtightening may cause damage.
8. Remove the backing from the self adhesive tape on the rear of the
Ratchet plate, and fix to the Spacer secured in the display.
The groove on the ratchet plate should face forwards and the protrusions
on the back of the ratchet plate should slot into the recesses in the end of
the spacer.
The display can now be trunnion mounted.
Trunnion bracket mounting
Once the display has been prepared using the instructions and parts
supplied, it can be mounted using the trunnion bracket as follows:
Note:
Fixings to secure the trunnion bracket to a mounting surface are not
provided. 5 x self-tapping screws are required. The screws should be
suitable for the mounting surface material and the 5.75 mm (0.23 in)
diameter mounting holes in the trunnion bracket.
Ensure you have chosen a suitable mounting location for your display, which
has sufficient headroom to allow the display's angle to be adjusted, or the
display to be removed if necessary. If installing the display 'above head
height', take extra care to ensure the knobs are tightened sufficiently to
prevent them coming loose due to vibration when underway.
Important:
2 person installation is required.

1. Check the underside of the mounting surface to ensure no damage will
be caused by drilling.
2. Check the thickness of the mounting surface to ensure it is sufficient to
support the display.
3. Using the Trunnion bracket as a template, mark and drill the 5 x pilot
holes on the mounting surface.
4. Secure the Trunnion bracket to the mounting surface using your
self-tapping screws and an appropriate screwdriver.
5. One person should align the trunnion holes in the side of the display with
the holes in the trunnion bracket.
6. The second person should secure the display to the trunnion bracket by
inserting and tightening the trunnion knobs, ensuring that the ratchet
teeth are correctly engaged.
The knobs should be tightened by hand, sufficiently to prevent the
display from moving whilst your vessel is underway.
7. Route and connect necessary cables.
