How can I restore my PC88 to its factory defaults?


Caution: Hard resetting will erase all user memory! Need be, save any custom programming via sys-ex dump before proceeding.

There are two methods for performing a hard reset on a PC88:

  • Global Menu Method:
    1. press GLOBAL
    2. press >>> until you see "Reset PC88?" (2nd to last item in menu)
    3. press [Yes] twice
  • -OR-

  • Boot Diagnostic Method: (useful if your screen is blank and cannot perform the Global menu method)
    1. start with the unit off
    2. hold down the 1, 2, & 3 buttons (on the alphanumeric keypad) and power up - release the buttons within two seconds of turning on the unit.
    3. press the <<< button under the display corresponding to Reset.
    4. turn the unit off and back on.

Via either method, the unit will "initialize" itself for about 5 sec. or so and then reboot to factory specs.

If the above methods do not successfully restore your unit's normal operation it will likely be time to take the unit to an authorized Kurzweil service center for repairs.
