DANGER
About explosion-proof

Do not modify or change the circuit or structure, etc.

When measuring the oxygen concentration, do not
measure anything but a mixture of air and
combustible gases or vapors and toxic gases.

When using the gas monitor in a hazardous area,
take the following countermeasures for preventing
dangers resulting from electrostatic charges.
(1) Wear anti-static clothes and conductive shoes
(anti-static work shoes).
(2) For indoor use, use the gas monitor while
standing on a conductive work floor (with a
leakage resistance of 10 M Ω or less).

The gas monitor has a different explosion-proof
class depending on the battery type.
Because it has a different certificate number too,
check the battery number against the certification
plate number before use.

Replace the batteries in a non-hazardous area.

Use only the batteries specified by RIKEN KEIKI on
this gas monitor.
WARNING
Fresh air adjustment in the atmosphere

When the fresh air adjustment is performed in the
atmosphere, check the atmosphere for freshness
before beginning the adjustment. If other gases
exist, the adjustment cannot be performed
properly, thus leading to dangers when the gas
leaks.
Battery level check

Before use, check that there remains sufficient
battery power. When the gas monitor is not used for
a long period, the batteries may be exhausted.
Replace them with new ones before use.

If a low battery voltage alarm is triggered, gas
detection cannot be conducted. If the alarm is
triggered during use, turn off the power and
promptly replace the batteries.
