Instructions
1. If you have a dropped ceiling, remove the ceiling tile.
2. Position the Mounting Bracket in the desired location.
Mark the three screw holes. If the CAT5/6 cable is wired
above the ceiling, mark a 25 mm hole as indicated
below.

3. Use a 1.6 mm drill bit to pre‑drill holes for the screws.
4. If the CAT5/6 cable is wired above the ceiling, cut or
drill the 25 mm circle you marked in step 2. This will be
used to feed the CAT5/6 cable through the ceiling.
