PA970 User's Manual
NOTICE
This unit is equipped with a battery pack and backup battery. It is possible that the Unitech PA970
may not immediately power-on due to battery discharge as a result of storage.
In the above situation, plug the PA970 to the RS232 or USB cable, or place the unit into the Unitech
PA970 Cradle (with 12V/2A AC-DC adapter, part number 1010-601478), and recharge the unit for 16
hours in order to fully charge its backup battery.
The backup battery will charge from external power or the main battery if the main battery still has
enough power to turn on. In the event the main battery is fully charged, refrain from using the PA970
for 16 hours in order for the main battery to fully charge the backup battery.
Backing-up data via backup battery only (without the main battery installed) may take as long as 4
hours. Therefore, in order to prevent data loss 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.
