Important
Carefully read the following points to get the best performance and long life from your
Handheld Terminal.
Handling Precautions
• 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 it with a wet cloth.
Do not use benzine, thinner, or other volatile chemicals, which can result in deformation of
the materials used in the keys and case.
• Do not lay the Handheld Terminal down with its key panel facing down. Doing so runs the
risk of accidental key operation, which may cause malfunction.
• 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 the Handheld Terminal dries completely before using
it.
Service
• If the Handheld Terminal has been damaged in any way, contact the store where you
purchased the Handheld Terminal and report the model, date of purchase, and a
description of the problem.
