Charging the Lithium-Ion Battery Pack

The optional Docking Station is a convenient accessory for
daily use of the PA970. Charging the battery pack using the
Docking Station takes approximately 3 hours.
Or, when using the included Charging/USB cable or Charging/
RS232 cable, the charging time of the battery pack is also
about 3 hours.

Charging the Main and Backup Battery for the First Time

Note: Before using the PA970 for the first time, charge the unit for 16 hours to fully charge the
empty backup battery. Operating the PA970 for the first time without the AC adapter, and
without fully charging the backup battery may result in loss of data stored in RAM memory.
Note: Backing-up data by backup battery only, without the main battery installed in the battery
compartment, may take as long as 4 hours. Therefore, in order to prevent data protection
failure due to backup battery failure, do not leave the PA970 without the rechargeable
battery pack installed, or without connection to AC power for an extended period of time.
It may take up to 96 hours to backup data when the PA970 is automatically shut down
because of very low battery power while the depleted batteries are still installed in
the battery compartment.
