3. It takes up to 3 hours for a fully discharged External Battery to reach a
full charge level when plugged into the unit and an AC or DC Adapter/
Charger. Press the Battery Check button to check the charging progress.
NOTE:
If both the Internal and External batteries are fully discharged, it
can take up to 7.5 hours to achieve a full charge level in both batteries.
4. When the External Battery is fully charged, the EXT Battery Check LED
will turn off.
In the event the power supply is interrupted to the POC when the AC or DC
Adapter/Charger is connected, a two-second audible alarm will sound and
the compressors will transition from external to internal power. During this
transition, you may hear the compressors momentarily pause. No action
is required as the system will automatically transition to internal power and
resume operation.
NOTE:
During and after charging, the internal fans may continue to operate
for an additional period of time until the temperature inside the unit is
sufficiently cooled.
REPRESSURIZATION
If the unit has not been used for a period of one or more days, it will
automatically re-pressurize itself. During this time, you may hear the
compressors running for a few seconds.
