7.1 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 UltraRAE monitor upon returning
from fieldwork. A fully charged battery powers an UltraRAE
monitor for 12 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 known to be non-
hazardous.
