Step 2 Place the device on the wall as reference or
reference installation dimension; mark 2 bolt
positions on the wall.
Step 3 Nail M4 screws on the wall and keep 2mm
interspace reserved.
Step 4 Hang the device on two screws and slide
downward, then tighten the screw to enhance
stability, mounting ends.
【Wall-mounted Device Disassembling】
Step 1 Device power off.
Step 2 Unscrew the screw on the wall about 2mm.
Step 3 Lift the device upward slightly; take out the device,
disassembling ends.
Note before powering on:
Power ON operation: First insert the power supply
