WARNING
To reduce the risk of ignition of hazardous atmospheres,
recharge battery only in an area known to be non-hazardous.
Remove and replace battery only in area’s known to be non-
hazardous.
When the display shows a flashing message “Bat”, the battery
requires recharging. The battery may be replaced in the field if
required. It is recommended to recharge the IAQRAE monitor
upon returning from fieldwork.
A fully charged battery powers an IAQRAE monitor for up to
36-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.
An alkaline battery adapter is supplied with each IAQRAE kit. It
may be used in place of the rechargeable Lithium-Ion battery
pack. The alkaline pack holds 6 C-size alkaline batteries. Use
only DURACELL Mn1400 or ENERGIZER E93 C-size batteries
with the IAQRAE alkaline battery pack.
