Sharp OZ-730 (deceased

SOURCE: Sharp Wizard OZ-730

Hi, I has this same problem but I found in the user manual this instructions and works ok: 1. Press and hold the Start key.
2. While holding down the Start key, push the RESET button
on the bottom of the Organizer using a pen or some other
pointed object. The following message will appear.
"Do you really want to initialize the organizer's memory (this will delete all data)? Yes:[ENTER/No:[ESC]
3. Press to initialize the Organizer.
The message .Working... Please wait.. appears while the
Organizer proceeds with the initialization procedure.
The Welcome message then appears.

The start key is the same as the power button. I pressed this down while doing the reset. Then I let go the reset while still holding down the power button. Worked like a charm.

This isn't really a solution, but be aware that the password IS case sensitive.

unscrew 3 little screws at the bottom cover using jewelry phillip driver-remove the cover- you will see further instructions inside the cover. This model requires 5 batteries CR2032 (4 for main memory-1 for backup memory)-Hope it helps.

Be sure the batteries are in correctly and are good, be sure the battery switch is back to the "normal position" - also it may have to be reset to work again - here is the instruction manual for doing that , page 7 chapter 1:
