OPERATION OF ACCESSORIES

3.1 Battery Charging Operation
The charging circuit of the AreaRAE is built into the monitor. It
requires a regular AC to 15 VDC adapter (a wall-mount
transformer) to charge the monitor.
1. Connect the AC adapter (or the optional automotive
charging adapter) to the charger port on the bottom of the
AreaRAE monitor.
2. An LED labeled “Charge” is located on the front of the
instrument. A red light indicates the battery is charging. A
green light indicates the battery is fully charged.
3. A completely drained AreaRAE monitor’s battery is
typically charged to full capacity within 10 hours.
Note:
The rechargeable Lithium-Ion battery pack slowly drains
even when the monitor is off. If the monitor has not been
charged for 5 to 7 days, the battery voltage will be low.
The factory-supplied battery is designed for up to 24 hours of
normal operation, without alarm conditions or backlight usage.
As the battery ages or is subjected to adverse conditions, such
as cold ambient temperatures, the battery capacity may be
significantly reduced.
