2) Loosen the battery cover by turning it counterclockwise
with a cross slot screwdriver with point size 2, and
remove the battery cover.
3) Pull the battery cover upward with fingers.

•
Make sure to use a screwdriver with
point size 2 (see on page 32 for the
shapes). If the screwdriver is too small,
the battery cover can be damaged.
•
Turn the screwdriver slowly. The battery
cover will be damaged if it is turned by
force.
NOTE
•
Make sure to use a new battery.
•
Low temperature may shorten the battery life due to the battery property. If
the remaining battery level is low, it is recommended to replace a battery
before it dies.

•
Replace a battery only in non-hazardous locations.
•
Make sure to use a Panasonic alkaline battery (LR03/AAA).
We cannot guarantee the intrinsically safe performance if an
unspecified battery is used. (Applicable battery model is listed
on a label of battery unit.)
•
Make sure to remove dust from O-ring of battery cover and
sealing between the Multi-gas Detector and battery cover, as
dust may be a cause of water ingress into the Multi-gas
Detector.
•
Always remove water and dust before opening the battery
cover. Entry of water or dust inside the Multi-gas Detector may
cause trouble.
•
If an O-ring of battery cover is damaged, be sure to replace
with a new one, as it may lead to water ingress into the
Multi-gas Detector.
