7.5 Battery Charger Status and Indicators
The Battery charger LEDs indicate the current charging state.
The bottom LED illuminates Green when the unit is connected to power.
The top LED is the status LED and conforms to the Table 11.
When the charge status LED flashes RED, a fault condition exists and when it flashes ORANGE you are receiving
an advisement concerning the condition of the PSD’s battery. There are two flash patterns for faults and two flash
patterns for advisements. Each is described in Table 11.
To initiate charging, place the PSD in a charging slot. The Top LED will initially illuminate RED to confirm the
battery is charging normally.
When charging is complete and after removing the PSD, the charge status LED will illuminate ORANGE for a few
seconds. Allow the charge status LED to go off before placing another PSD in the charging pod.
