Note:
Backing-up data by backup battery only without the main battery installed
in the battery compartment may take as long as 6 hours. Therefore, in order to
prevent data protection failure due to backup battery failure, do not leave the
PA962 without the rechargeable battery pack installed, or without connection to
AC power for an extended period of time.
It may take up to 72 hours to backup data when the PA962 is automatically shut
down because of very low battery power while the depleted batteries are still
installed in the battery compartment.
Note:
Before using the PA962 for the first time, charge the unit for 16 hours to
fully charge the empty backup battery. Operating the PA962 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.
