Safety

Use the following safety guidelines to help protect yourself and the PWS-440.



Do not attempt to service the PWS-440 yourself. Always follow installation 
instructions closely.



Be sure that nothing rests on the AC adapter's power cable and that the cable is 
not located where it can be tripped over or stepped on.



Do not cover the AC adapter with papers or other items that will reduce cooling; 
also, do not use the AC adapter while it is inside a carrying case.



Use only the AC adapter, power cord, and batteries that are approved for use 
with this PWS-440. Use of another type of battery or AC adapter may cause risk 
of fire or explosion.



If you use an extension cable with the AC adapter, ensure that the total ampere 
rating of the products plugged in to the extension cable does not exceed the 
ampere rating of the extension cable.



When you move the PWS-440 between environments with very different tem-
perature and/or humidity ranges, condensation may form on or within the PWS-
440. To avoid damaging the PWS-440, allow sufficient time for the moisture to 
evaporate before using the PWS-440.



When you disconnect a cable, pull on its connector or on its strain relief loop, 
not on the cable itself. As you pull out the connector, keep it evenly aligned to 
avoid bending any connector pins. Also, before you connect a cable make sure 
both connectors are correctly oriented and aligned.

Battery Safety



There is a risk of explosion if the battery is replaced by an incorrect type.



Dispose of used batteries according to the instructions.



Do not dispose of batteries in a fire. They may explode. Check with local author-
ities for disposal instructions.

Notices

This unit is equipped with a battery pack and backup battery. It is possible that the
PDA may not power-on due to battery discharge as a result of storage.

In the above situation, insert the PDA into the cradle and connect the AC adapter.
Recharge the unit for 3 hours in order to fully charge its battery. The backup battery
will recharge from external power when the AC adapter is connected.

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 0°C to 50°C. charging batteries outside of the specified range could damage the
batteries and shorten their charging life cycle.

Storage and safety notice

Although charged Lithium-Ion batteries may be left unused for several months, their
capacity may be depleted due to build up of internal resistance. If this happens they
will require recharging prior to use. Lithium-Ion batteries may be stored at tempera-
tures between -20°C to 50°C, however they may be depleted more rapidly at the high
end of this range. It is recommended to store batteries within normal room tempera-
ture ranges.
