REQUIRED
TOOLS
- Small flat head screwdriver for opening the transmitter and for
screw terminals.
- Two screws, max Ø 4 mm.
- Depending on the wall material and screw type, you may need a
drill and a suitable drill bit to make installation holes for screws.
- Tools for cutting and stripping wires.
1.
Use a flat head screwdriver to push down the tab on top of the

at least two screws (not included, max Ø 4 mm).
NOTE The arrow on the mounting base must point straight up after installation.
Proper orientation is important: air must flow through the vents on the
