Read this first!
•Be sure to read this part of the User’s Guide before doing anything else! It
includes important information that you need to know in order to use the
PV-S250/PV-S450 (hereinafter referred to as the “PV Unit”) correctly.
• You can find more detailed information about other PV Unit operations in
“Chapter 14 – General Operations” on page 149 and “Chapter 16 – Technical
Reference” on page 172.
Important!
Please keep this User’s Guide and all information handy for future reference.
Note
The screen shots shown in this User’s Guide may differ slightly from the displays
actually produced by your PV Unit.
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.
• Avoid 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.
• Avoid 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.
• Make sure nothing gets between the hard cover and the touch screen.
Besides creating the risk of scratching the touch screen, an object coming
into contact with the screen can cause power to turn on and run down
the batteries.
• 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.
• The contents of this manual are subject to change without notice.
• CASIO COMPUTER CO., LTD. assumes no responsibility for any loss
or claims by third parties that may arise from the use of this product.

Chapter 1 Getting Acquainted
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.

Power Supply
Your PV Unit can be powered by twoAAA-size alkaline batteries.
Important!
• Normally the flash memory of the PV Unit retains its data even when power
is turned off and when batteries go dead. Mis-operation or other problems,
however, can cause data to become corrupted or lost. Always keep separate
copies of important data.
Low Battery Warning
The message shown below appears whenever battery power drops below a
certain level. Replace the batteries immediately after this message appears:
Batteries are getting weak! Replace them as instructed in the User’s
Guide.
Important!
• If you continue using the PV Unit after the low battery warning message
appears, power may suddenly turn off or the contrast adjustment screen
may suddenly appear. Should this happen, replace batteries immediately.
• Be sure to use alkaline batteries. Manganese batteries provide very short
battery life.
Battery Precautions
Incorrectly using batteries can cause them to burst or leak, possibly damaging
the interior of the PV Unit. Note the following precautions.
• Be sure to use alkaline batteries only to power this PV Unit.
• Be sure that the positive (+) side of each battery is
facing in the correct directions.
• Never mix batteries of different types.
18
• Never mix old batteries and new ones.
• Do not expose batteries to direct heat, let them become shorted, or try to
take them apart.
• Never leave dead batteries in the battery
compartment.
• Remove the batteries if you do not plan to use the PV Unit for a long
time.
• Replace batteries at least once every year, no matter how much you use
the PV Unit during that period.
• About once a month, turn on the PV Unit and check its battery level. If
the low battery warning appears or if nothing at all appears on the display,
replace batteries as soon as possible.
• Never try to recharge the batteries that come with
the PV Unit.
• Should a battery leak, clean out the battery compartment of the PV Unit
immediately, taking care to avoid letting battery fluid come into direct
contact with your skin.
Keep batteries out of the reach of small children. If swallowed, consult
with a physician immediately.
• Frequent data synchronization using the PC sync for Windows
application that comes with the PV Unit shortens battery life.
• The batteries that come with this unit discharge slightly during
shipment and storage. Because of this, they may require replacement
sooner than the normal expected battery life.
