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.
• The contents of this manual are subject to change without notice.

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.
11
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
“To reset the PV Unit” on page 182.

Power Supply
Your PV Unit can be powered by two AAA-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.
14
Chapter 1 Getting Acquainted
• 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.
• 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.
15
To replace the batteries
Important!
• Always make sure the battery switch is in the NORMAL OPERATION
position at all times, except when replacing batteries.
1. Turn off PV Unit power.
2. Slide the battery switch on the back of the PV Unit to the REPLACE
BATTERIES position.

Chapter 1 Getting Acquainted
To turn power on and off
1. Touch anywhere on the PV Unit screen or press the Action control to
turn on power.
2. To turn power off, tap Off with the stylus.
Auto Power Off
The Auto Power Off function automatically turns off power whenever
you do not perform any operation for a specified period. You can specify
1 minute, 3 minutes, or 6 minutes before Auto Power Off is triggered
(page 166).
Use the procedure described under “To turn power on and off” above to
turn power back on.
Using the Backlight
T apping the Light icon beneath the PV Unit screen illuminates the display screen
for about 15 seconds for easy viewing, even in the dark.
• Tapping the Light icon while the backlight is on turns it off.
• The backlight may fail to turn on when battery power is low and during data
communication.
Action Control and Stylus
Many of the PV Unit’s operations can be performed using either a stylus or the
Action control on the left side of the unit. The following describes the general
operations that can be performed with each.
19
Stylus
The stylus takes the place of a computer mouse. You can perform all PV
Unit operations with the stylus. In this manual, all data input operations are
described using stylus operations.
You can perform the following basic operations with the stylus.
• Tap
Tap the tip of the stylus on the display to press a button, select an item,
select a data input field, etc.
• Double-tap
Tap the display twice in relatively quick succession.
• Drag
Touch the tip of the stylus to the screen, and drag it across the screen to
select a range of text, draw a line, etc.
Action Control
The Action control makes it possible to perform certain PV Unit operations
with one hand. In this manual, many data recall operations are described
using Action control operations.
You can perform the following basic operations with the Action control.
• Rotate
Rotating the Action control up and down causes the selection or data on the
screen to scroll up and down.
• Press
Pressing the Action control is much like a “click” on a computer mouse
button. Pressing the Action control executes the command that is highlighted
on the display, executes the function assigned to the button whose name is
enclosed by a dotted line (such as
screen, etc.
