Introduction
Make sure you carefully read the following information to ensure that your Handheld Terminal
is able to perform at the level for which it is designed.
Handling Precautions
· Do not throw or drop the Handheld Terminal or otherwise subject it to strong impact,
which
can damage the LCD screen, interrupt program execution, corrupt memory contents, or
otherwise interfere with proper operation.
· Use only your finger or a blunt object to operate the stroke keys. Use of a sharp pointed
object can damage stroke keys and cause shorting of internal circuitry.
· Use a soft, dry cloth when cleaning the Handheld Terminal. Do not wipe with a wet cloth.
Do not use benzine, thinner, or other volatile chemicals, which can result in deformation
and deterioration of the materials used in the keys and case.
· Do not lay the Handheld Terminal down with its key panel downwards. Doing so runs the
risk of accidental key operation, which can cause malfunction.
· Never remove the main battery while Handheld Terminal power is turned ON. Doing so
can cause all data in memory to be lost.
· Sudden temperature changes can cause condensation to form on the Handheld Terminal’
s
case. Operating the Handheld Terminal while condensation is present can interfere with
proper operation. Take care to avoid conditions that cause the formation of condensation.
If
condensation does form, wait until it dries completely before using the Handheld Terminal.
