Do not use the instrument near a source of
strong electromagnetic radiation, or near a
highly electrically charged object.
These may cause a malfunction.
Operation and Installation environment.
This instrument should be installed and operated
indoors only, between 0 and 50°C (32 to 122°F)
and 80% RH or less.
This instrument is not designed to be entirely
water- or dust-proof.
Do not use it in an especially dusty environment,
nor where it might be splashed with liquid. This
may cause damage.
When the module is used in a dusty environment,
place it in a dustproof case and take measures to
ensure heat dissipation.
Do not store or use the instrument where it
could be exposed to direct sunlight, high tem-
perature or humidity, or condensation.
Under such conditions, the instrument may be
damaged and insulation may deteriorate so that it
no longer meets specifications.
To avoid damage to the instrument, protect it
from physical shock when transporting and
handling.
Be especially careful to avoid physical shock from
dropping.
Do not obstruct the ventilation holes.
Ventilation holes for heat radiation are provided on
the top and rear panels of the instrument. Leave
sufficient space around the ventilation holes and
install the instrument with the holes unobstructed.
Installation of the instrument with the ventilation
holes obstructed may cause a malfunction or fire.
