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.

This unit is equipped with a battery pack and backup battery. Both batteries will discharge after an extended period

of not being used.

When both batteries are discharged, recharge the unit for 16 hours in order to fully charge the main battery and

backup battery. There are two ways to recharge PA500:

1. Plug the USB charging cable to the PA500 and plug the 5V/2A AC-DC adapter to the power jack of the USB

charging cable.

2. Place the PA500 into the docking station and plug the 5V/2A AC-DC adapter to the power jack of the docking

station.

For more details, refer to page 6, Charging the PA500.

If the main battery is removed, the backup battery ensures the data on SDRAM is safe for up to 1 hour. To prevent

data loss, do not leave the PA500 uncharged with the main battery removed for an extended period.
