◆ Motion sensor kit PS-MSK2 (optional)
Do not install the motion sensor kit PS-MSK2 (optional) in the following places.
It may cause misdetection, undetectable of motion or the deterioration of the motion sensor.
• Places where ambient temperature changes drastically.
• Places where excessive force or vibration is applied to the motion sensor.
• Places where static electricity or electromagnetic waves may generate.
• Places where is interference for infrared light such as glasses or mist in a detecting area.
• Places where the lens for motion sensor is exposed in high temperature and humidity for a long
time.
• Places where fluid and corrosive gas exist.
• Places where direct lights such as sunlight or headlight affect the motion sensor.
• Places where hot air from a heater, etc. affects directly the motion sensor.
• Places where weather affects directly the surface of the motion sensor.
• Places where the lens surface may smudge or be damaged such as a dusty environment.

Pay attention that the detecting function will be decreased if the lens for motion sensor smudges.
In this case, wipe off smudges by a cotton swab soaked alcohol (Isopropyl alcohol is recommended)
or a soft cloth.
When wiping off smudges on the lens for motion sensor, do not apply excessive force.
If excessive force is applied, the resin lens may be damaged so that may cause malfunctions such
as misdetection or undetectable of the motion.
