3.7.3 Securing with Mounting Screws

Mounting screw holes are provided on the rear side of the unit, which are attached with
mounting magnets by default. The unit can be screw-mounted through the holes by removing
the magnets. (Refer to the Appendix: Installation Diagram for the screw hole dimensions.)

Important
The screw holes are 4 mm deep. Do not screw deeper than 4 mm, which may damage
the product.

3.7.4 Screw Hook Mounting

Two screw hook holes are provided on the rear top of the unit (immediately below the
protrusions on the top), which allow easy mounting of the unit on the wall or other vertical
surface. (Refer to the Appendix: Installation Diagram for the screw hooking hole dimensions.)
Pre-mount the M3 screws on the wall surface and hook the unit on the screws through the
holes. Mount the screws allowing a distance of 2.5 mm or more between the screw head and
the surface.
Important
Firmly hold the unit with your hand to insert or remove the SD card when the unit is
mounted by hooking. Otherwise the unit may drop on the floor and be damaged.
