Battery Status Indicator
When the startup sequence is complete, the BATTERY STATUS INDICATOR will show current battery life status.
While the unit is on, the status is updated once every second. Battery status indicator is not visible if the DV-41
is connected to external power source (AC adapter).
Battery voltage status is as follows:
When the battery voltage drops below 2.4 volts, the battery outline will flash and the unit will beep once per
minute to alert the low battery condition. When battery voltage falls below 2.1 volts, the shutdown timer is
activated. If voltage stays below 2.1 volts for thirty seconds, the DV-41 will beep once and power off. If power
is restored during this time, shutdown is canceled.
