OPERATION OF ACCESSORIES

3.1 Battery Charging Operation
The charging circuit of the AreaRAE-Gamma is built into the
monitor. It requires a regular AC to 15 V DC 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-Gamma 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-Gamma monitor will be
charged to full capacity within 10 hours.
NOTE:
The rechargeable Lithium-Ion AreaRAE-Gamma
battery pack will slowly drain even when the monitor is off. If
the monitor has not been charged for 5-7 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 temperature, the battery capacity may
significantly reduce.
