1.1 BATTERY CHARGING

Always fully charge the battery before using the instrument. The screen will display a
battery icon from empty (no bars) to fully charged (3 bars).
Follow this procedure to charge the instrument:
1. Plug the Micro-USB into the charging port at the bottom of the instrument.
2. Plug the USB connector* into either a) a personal computer, or b) into the AC/DC
adapter and plug the AC/DC adapter into the wall outlet.
The instrument begins charging automatically. The charging LED turns red
to indicate charging. During charging, the 3 bars in the battery icon on the
instrument's display are animated. When the battery is fully charged, the
LED turns green, the icon is no longer animated and shows a full battery,
and the message 'Fully Charged' is displayed.
*NOTE: Any locally-obtained USB A to Micro B USB cable will work for charging, but
will not work for communication with WatchGas Suite configuration and data transfer
software. The WatchGas USB cable P/N M-011-3003-000 is required for a PC to
recognize the instrument and communicate with WatchGas Suite.
WARNING
To reduce the risk of ignition of hazardous atmospheres, recharge
and replace batteries only in areas known to be non-hazardous.
Use only WatchGas's rechargeable lithium battery part number:
M011-3002-000.

1.2 LOW VOLTAGE WARNING

When the battery's charge falls below a preset voltage, the instrument
warns you by beeping once and flashing once every minute, and the
"empty battery" icon blinks on and off once per second. Turn off the
instrument within 10 minutes and either recharge the battery, or replace
the battery with a fresh one with a full charge.

1.3 CLOCK BATTERY

An internal clock battery is mounted on one of the instrument's printed circuit boards.
This long-life battery keeps settings in memory from being lost whenever the Li-ion
battery or alkaline batteries are removed. This backup battery should last approximately
five years, and must be replaced by an authorized WatchGas service technician. It is not
user-replaceable.
