• Ensure the monitor is switched on and the sensor and
audible port are unobstructed prior to use.
• This detector is a personal safety device. It is your
responsibility to respond properly to any alarm
conditions.
• Do not use the device if it appears to be damaged.
Always inspect it before use and look for blocked filters
and physical damage.
• Periodically test the response of the sensors by
exposing the detector to a target gas concentration
that exceeds the alarm set point. Manually verify that
the audible, vibration, and visual alarms are activated.
• For safety reasons, this equipment must be operated
and serviced by qualified personnel only.
• Do not attempt to replace the internal components.
This will void the intrinsic safety rating and will void
the warranty of the product. (Unless replaced by a
WatchGas-approved service technician using original
WatchGas parts.)
• Deactivating the detector by removing the battery
pack may cause improper operation and harm to the
detector.

fire, explosion, and chemical burn if misused. Do not
disassemble, incinerate, or heat above 212°F (100°C).
Batteries exposed to heat at 266°F (130°C) for 10
minutes can cause fire and explosion.
• Batteries must only be charged in a safe area free of
hazardous gas.
• Only use WatchGas chargers. Using other Non-
Approved chargers can lead to fire and/or explosion.
(The Wireless charger used in conjunction with the
equipment must be a suitably approved SELV / PELV
supply with a maximum voltage not exceeding 5 V.)
• This instrument contains a lithium polymer battery.
Do not disassemble and do not dispose of in fire. Do
not mix with the solid waste stream.
• Used batteries must be disposed of by a qualified
recycler or hazardous materials handler.
CAUTIONS/SPECIAL CONDITIONS
• All inspections should be performed in a clean and
hazardous-free environment.
• The detector should be cleaned with a soft damp
cloth using a neutral cleaner (i.e. ACL Staticide). NOTE:
Do not use solvents, soaps, or polishes.
• This product is a gas detector, not a measuring device.
• For optimal performance, periodically zero the
sensor in a normal atmosphere (20.9% v/v O2) that is
free of hazardous gas.
• This equipment is intended for use in hazardous
