CP860 doesn't boot

[complex1]

Hi,

Please try this:
- Remove power from the CP860
- Press and hold the “OK” button on the keypad
- Power on the CP860, wait 20 sec. and release the “OK” button.
- The LCD promote “Reset to factory setting?” Choose “OK” to reset the phone.
The CP860 should now be in the factory default settings.

Hope this helps.
