Battery
Fully charge the POLI batteries upon receiving the mSquad and before each day’s use. The Li-
ion batteries are charged using a Micro-USB cable.
WARNING
To reduce the risk of ignition of hazardous atmospheres, recharge, remove or replace the battery
only in an area known to be non-hazardous!
2.1 Battery Charging
Up to four POLI monitors can be charged simultaneously using the cables inside the mSquad
carry case. Plug the mini ends of the Micro-USB cables into the charging port of each POLI, and
the power adapter into a wall socket (100-240 VAC). The POLIs can also be charged
individually on a personal computer using the USB power/communications cables provided.
NOTE
: Any locally-obtained USB A to Micro B USB cable works for charging, but does not
work for communication with mPower Suite configuration and data transfer software. The
mPower USB cable P/N M-011-3003-000 is required for a PC to recognize the instrument and
communicate with mPower Suite.
The screen will display a battery icon from empty to full and one alarm LED will remain yellow.
When the battery is fully charged, the icon displays full grid status (see Section 3.1), and the
alarm LED turns green.
2.2 Battery Status
The battery icon on the display shows the battery level, and alerts of any charging problem.

Battery Alarm
When the battery’s charge falls below a preset voltage, the instrument warns by beeping once
and flashing once every minute. The instrument automatically powers down within 10 minutes,
after which the battery must be recharged. When a low-battery alarm occurs, we recommended
promptly switching instruments to a fully charged POLI, and/or charging the battery in a non-
hazardous location.
