Make backup copies of important data!
Your PV Unit employs flash memory, which makes it possible to store large volumes of data and to recall data quickly and easily . Data is retained when power is turned off and even when batteries go dead, but it can be corrupted or lost entirely due to operational mistakes or malfunction. Data contents can also be corrupted or lost due to strong electrostatic charge, strong impact, or extremes in temperature and humidity. All of this means that you should always keep back-up copies of important data by transferring it to a personal computer or by writing it down somewhere.
Important Precautions
Note the following important precautions whenever using your PV Unit.
Never expose the PV Unit to fire.
A void temperature extremes. Do not locate the PV Unit in direct sunlight, near a window, near a heater, etc.
In very low temperatures display response may slow down or fail entirely . This condition is temporary and operation should resume under normal temperatures.
Avoid areas subject to excessive moisture, dirt, and dust.
A void dropping the PV Unit and otherwise subjecting it to strong impact.
Never bend or twist the PV Unit.
Never try to take the PV Unit apart.
Do not use a pen, pencil, or other sharp object to touch or press the display .
To clean the exterior of the PV Unit, wipe it with a soft cloth dampened in a weak solution of a mild neutral detergent and water. Be sure to wring out any excess moisture from the cloth before wiping off the PV Unit. Never use benzene, thinner, or any other volatile agent to clean the unit. Doing so can remove the figures printed on the case or otherwise damage the case finish.

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.
