27.1 Battery Charging & Replacement
When the display shows a flashing empty battery icon, the battery
requires recharging. It is recommended to recharge the instrument
upon returning from fieldwork. A fully charged battery runs a
instrument for 16 hours continuously. The charging time is less than 8
hours for a fully discharged battery. The battery may be replaced in
the field (in areas known to be non-hazardous), if required.
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 areas known to be non-hazardous.
