Low voltage shutdown
When the battery charge (for the battery providing power to the
SmartReader) drops to below one bar the low battery beep sounds (four
beeps) to indicate the battery has low voltage. This will continue regularly
until the battery level becomes critical or until you charge the battery.
This applies for both the internal and external (if connected) batteries.
When the battery charge (for the battery providing power to the
SmartReader) drops to a critical level, the SmartReader shuts down. During
the shut down process the low battery beep sounds (four beeps) and the
display shows BATT. The critical level occurs when the battery voltage drops
below 11.5 volts.
Replace the external battery or recharge the internal batteries.
For further information on connecting an external 12 volt battery, see
Connecting to an external 12 volt battery (p 10).
Note: This warning sounds regardless of the volume level setting.
