In the detection mode, put the gas sampling probe close to the detection area and take the reading on the
display.

DANGER
• While conducting measurement in a manhole or confined space, do not lean over or look into the
manhole or closed space. It may lead to dangers because oxygen-deficient air or other gases
may blow out.
• Oxygen-deficient air or other gases may blow out from the gas exhausting outlet. Never inhale
the air or gases.
• High-concentration (more than LEL) gases may blow out. Never use fire near the gas monitor.
WARNING
• The gas monitor is designed to draw gases around it under the atmospheric pressure. If
excessive pressure is applied to the gas inlet and outlet (GAS IN, GAS OUT) of the gas monitor,
detected gases may be leaked from its inside, thus leading to dangers. Be sure that excessive
pressure is not applied to the gas monitor while used.
• Do not connect the sampling hose directly to a location with a pressure higher than the
atmospheric pressure. The internal piping system may be damaged.
• 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.
• Issuance of a gas alarm indicates that there are extreme dangers. Take proper actions based on
your judgment.
• Before use, check that there remains sufficient battery power. When the gas monitor is used for
the first time or is not used for a long period, the batteries may be exhausted. Either fully
recharge the batteries or replace them with new ones before use.
• If a low battery alarm occurs, gas detection cannot be conducted. If the alarm occurs during use,
turn off the power and promptly recharge the batteries in a non-hazardous area.
• Do not block the buzzer sound opening. No alarm sound can be heard.
