MAINTENANCE
6.1 Battery Replacement
When the display shows a flashing message "Bat", the battery
requires recharging. The battery may be replaced in the field
(in area known to be non-hazardous) if required. It is
recommended to recharge the AreaRAE-Gamma monitor upon
returning from fieldwork. A fully charged battery powers an
AreaRAE-Gamma monitor for up to 24-hours continuous
operation. The charging time is less than 10-hours for a fully
discharged battery. The built-in charging circuit is controlled by
two-step constant voltage / constant current charging to
prevent over-charging.
WARNING
To reduce the risk of ignition of hazardous atmospheres,
recharge battery only in area known to be non-hazardous.
Remove and replace battery only in area's known to be non-
hazardous.
