N O T E
• 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.
a Places where ambient temperature changes drastically.
b Places where excessive force or vibration is applied to the
motion sensor.
c Places where static electricity or electromagnetic waves may
generate.
d Places where is interference for infrared light such as glasses or
mist in a detecting area.
e Places where the lens for motion sensor is exposed in high
temperature and humidity for a long time.
f Places where fluid and corrosive gas exist.
g Places where direct lights such as sunlight or headlight affect
the motion sensor.
h Places where hot air from a heater, etc. affects directly the
motion sensor.
i Places where weather affects directly the surface of the motion
sensor.
j 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.
