When mounting to drywall, use
the specified holes (see Figure 2) with the provided
spring clips. Other mounting may cause the screws
to damage the PCB or cause a short circuit.
IMPORTANT:
To prevent drywall damage,
do not overtighten the screws.
6. To install the PCB into the base, refer to Figure 3
and:
•
align the PCB over the latch pins on the base.
•
press down on the board until it snaps into
place and is secured by the latches.
