pipes in the space directly behind where the mount will be installed.
2. The bottom of the mounting template sticker should be level and at least 103cm from
the ground, and its top should have at least 30cm* of clearance above it. (*30cm: Leave
enough space just in case you may need to purchase the replaceable battery in the
future.)
3. Use a power drill with an 8 mm drill bit to drill a hole into each hole marker on the
mounting template sticker, then insert a wall plug into each hole.
4. Align the position holes on the mount with the holes on the wall. Fasten it to the wall with
the included screws.
