NOTICE
This unit is equipped with a battery pack and backup battery.
Please be reminded to
turn on the backup battery underneath the PCMCIA cover before you
start to install main battery into PT930SA for the first time (as shown in
blow photo)
. It is possible that the Unitech PT930SA may not power-on due to battery
discharge as a result of storage.
In the above situation, plug the PT930SA to the RS232-Charging cable or put the unit into the
Unitech PT093 Cradle (with 9V/2A AC-DC adapter), and recharge the unit for 8 hours in order
to fully charge its backup battery. (It is not necessary to power on the PT930SA in order to
charge the 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 PT930SA for 8 hours in order for the main battery to fully charge the backup battery.
Backing-up data by backup battery only without the main battery installed in battery compart-
ment may take as long as 2 hours. Therefore, in order to prevent data protection failure due to
backup battery failure, do not leave the PT930SA without the rechargeable battery pack installed,
or without connection to AC power for an extended period of time.
