ZPDA (250-3100)              AC Adapter              Faxback Doc. # 2637

You can use an optional AC adapter with the unit. Use only an adapter with
the same voltage rating as the power supply in your area. Plug the AC
adapter into a household outlet and then plug the adapter cord into the
unit. When you do this, power from the batteries are automatically cut off.

- Use only the AC adapter specified below:

  (Radio Shack 16-2018) or (Casio AD-B60080)

  The AC adapters output plug polarity must be as follows:
       
     Inner Tip = Negative
     Outer Tip = Positive

- The adapter might become warm when it is being used. This is normal and
  does not indicate any problem.
- Be sure to unplug the adapter from the power source when you are not
  using the unit.
- When connecting or disconnecting the adapter, be sure the unit's power
  is off.
- You cannot use the AC adapter when the main batteries are not loaded in
  the unit.
- This adapter is dual polarity. The inner tip is negative, the outer tip
  positive.
