Battery Notices
This unit is equipped with a battery pack and backup battery. It is possible that the unitech
PA500 may not power-on due to battery discharge as a result of storage.
In the above situation, plug the PA500 to the USB charging cable which is with DC in port or
put the unit into the unitech PA500 USB Docking Station (with 5V/3A AC-DC adapter), 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 PA500 for 16 hours in order for the main battery to fully charge the backup battery.
Backing-up data by backup battery only withut the main battery installed in battery
compartment may take as long as 1 hour. Therefore, in order to prevent data protection failure
due to backup battery failure, do not leave the PA500 without the rechargeable battery pack
installed, or without connection to AC power for an extended period of time.
Battery Charge Notice
It is important to consider the environment temperature whenever you are charging the
Lithium-Ion battery pack. The process is most efficient at normal room temperature or slightly
cooler. It is essential that you charge batteries within the stated range of 0°C to 50°C.
Charging batteries out of the specified range could damage the batteries and shorten their
charging life cycle.
