bulkhead or deckhead, as shown in the following diagram.
1. Loosen the trunnion knobs and remove the trunnion from the display unit.
2. Mark the locations of the trunnion screw holes on the mounting surface.
3. Use the screws supplied to fix the trunnion at the marked locations.
4. Fit the unit to the trunnion, adjust the display angle and tighten the knobs.

CAUTION:
Make sure that there are no hidden electrical wires or other items behind
the location before proceeding. Make sure that there is sufficient rear
access for mounting and cabling. Allow at least 4cm at the right hand side
of the display to enable chart cards to be inserted and removed.
