User manual

- Do not attempt to open or repair the unit without qualified electrician while
it is malfunctioned.
- The following conditions may cause lower sensitivity:
- In very foggy nights, the sensitivity may be less due to moisture collecting
on the lens.
- In very hot days, the sensitivity may be less since high ambient
temperature is close to body temperature
- In very cold days when heavy clothing is dressed, especially the facial
area is covered, very little heat will be emitted from the body causing the
unit to be less sensitivity.
- Cleaning wipe with dry cloth only. Soap or rough cloth may damage the
detector lens.
