Laser Information
The unitech PA600 series is certified in the U.S. to conform to the requirements of
DHHS/CDRH 21CFR Subchapter J and to the requirements of IEC 825-1. Class II and
Class 2 products are not considered to be hazardous. The PA600 series contains
internally a Visible Laser Diode (VLD) whose emissions do not exceed the maximum
limits as set forth in the above regulations. The scanner is designed so that there is no
human access to harmful laser light during normal operation, user maintenance or
during prescribed service operations.
The laser safety warning label required by the DHHS/IEC for the PA600 series's
optional laser scanner module is located on the memory compartment cover, on the
back of the unit.
CAUTION!
Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous laser light. Use of
optical instruments with the scanner will increase eye hazard. Optical
instruments include binoculars, microscopes, and magnifying glasses.
This does not include eye glasses worn by the user.
Battery Notices
This unit is equipped with a battery pack and backup battery. Both batteries will dis-
charge 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 PA600:
1. Plug the USB charging cable to the PA600 and plug the 5V/2A AC-DC adapter to
the power jack of the USB charging cable.
2. Place the PA600 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 8, Charging the Battery.
If the main battery is removed, the backup battery ensures the data on SDRAM is safe
for up to 6 hours. To prevent data loss, do not leave the PA600 uncharged with the
main battery removed for an extended period.
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 tempera-
ture or slightly cooler. It is essential that you charge batteries within the
stated range of -5°C to 50°C. Charging batteries outside of the specified range could
damage the batteries and shorten their charging life cycle.
