OPERATION OF ACCESSORIES
3-3
Recharging the Lithium-Ion Battery Pack
1. Turn IAQRAE off.
2. The charging circuit of the IAQRAE is built into the monitor.
It requires a regular AC to 15V DC adapter (a wall mount
transformer) to charge the monitor.
3. Connect the AC adapter (or the optional automotive
charging adapter) to the charger connection port on the
IAQRAE monitor.
4. When the Charge LED located on the front of the monitor
is red, the battery is charging. A completely drained
IAQRAE will be fully charged within 10 hours.
5. When the LED turns green, the battery is fully charged.
Note:
The rechargeable Lithium-Ion IAQRAE battery pack will
slowly drain even when the monitor is off. If the monitor has not
been charged for several days, the battery voltage may be low.
The factory-supplied battery is designed for up to 36 hours of
normal operation, without alarm conditions or backlight usage.
As the battery ages or is subjected to adverse conditions, such
as cold ambient temperature, the battery capacity may
significantly reduce.
Removing or Replacing the Alkaline Battery Adapter
1.
Before
removing or replacing the battery pack, please
make sure the IAQRAE monitor is located in a non-
hazardous area and is not connected to the charger.
2. To remove the battery pack, unscrew the four screws that
secure the battery pack to the IAQRAE housing.
3. Remove and replace drained alkaline batteries.
4. Match the battery polarity as indicated by the diagram
inside the battery holder.
5. Reattach the battery pack to monitor.
Note:
The internal charging circuit will automatically detect the
alkaline battery adapter and will not charge the battery adapter.
