ZPDA  (250-3100)                Hints                  Faxback Doc. # 2642

To help prevent possible information loss, follow these precautions at all
times:

- Never take apart the unit.
- Do not drop the unit.
- Avoid sudden temperature changes.
- Promptly replace the batteries when the low-battery warning appears.
- Even if you do not plan to use the unit for a long time, replace the
  batteries periodically to prevent damage from leakage. Replace the main
  batteries at least once a year and the backup batteries at least once
  every five years.
- Never use thinner, benzene, or other solvents or strong detergents to
  clean the case.  Use only a soft cloth moistened with water and a mild
  soap. Wring out the cloth until it is barely damp to prevent drops of
  water from contacting internal parts.
- Use a soft cloth to clean the screen.
- If you try to use the unit when it is very cold, the display might not
  operate.  This is temporary. Gradually return the unit to a normal room-
  temperature environment before you use it.
- If the unit is exposed to a strong electrostatic charge, the screen might
  dim or the unit might lock up. To correct this situation, perform a soft
  reset.
