screws, using some of the six mounting holes.

Caution: This device must not be placed near any louver, air vent, or other
places exposed to fresh air (e.g., windows, door openings). Such placement
will give false CO

values.

Attach the sensor part to the back panel.

Service and maintenance

No serviceable parts inside. If service is needed other than battery replacement,
