If you change setting for function switches, the equipment cannot perform as it is supposed to, for example,
alarm does not go off even when there is gas leakage. Do not change setting unless you completely
understand features of Function switches.
CAUTION
When gas leaks indoors, open windows and doors for better ventilation.
Use our Gas Leak Detector XP-702S / XP-703D to efficiently find where the gas is leaking from.
MEMO
In case of an alarm, carry out your predetermined measures for gas leakage.
WARNING
Replace two batteries at the same time.
Do not catch the harness when attaching the battery cover.
