Data Errors
The PV Unit performs a self-check routine whenever you turn it on. The message
shown below appears if the PV Unit detects a problem with data stored in its
memory.
Once data is lost due to a data error it cannot be recovered. Data errors are generally
caused by one of the following problems.
• Interruption of battery power
• Severe electrostatic charge, strong impact, changes in temperature, or
changes in humidity
• Hardware problems
Once the data error message appears, the PV Unit will not accept any input or
editing of data. In order to return memory to normal (and permit further data
editing and input), you have to perform the RESET operation to clear all data.
Before doing so, you may want to recall important data and write it down (if you
don’t yet have a copy). You can then re-input the data after clearing PV Unit
memory.
Continued problems after performing the RESET operation can indicate a serious
hardware problem. Consult with your nearest CASIO dealer if problems persist.
To reset after viewing data
1. After the Data error message appears, tap Yes .
2. In response to the message that appears (Data error! Consult your
User’s Guide for correct procedure.), tap OK.
• This displays the pop up tool screen.
3. Now you can enter other modes to recall data and make handwritten
copies if you want.
4. After recalling the data you want, perform the RESET operation under
“Resetting the PV Unit” on page 176.
