About the EL backlight  
•
This unit is equipped with an EL backlight that allows easy viewing of display  
contents in a theater, or anywhere else where lighting is dim.  
Note, however, that frequent or extended use of the EL backlight shortens  
battery life.  
•
The following shows how backlight use affects battery life under controlled test  
conditions.*

•
“Battery Life” is the number of hours before battery failure when the unit is left  
on with 5 minutes of a processing operation and 55 minutes of continuous  
display only (no processing operation) per hour, plus the backlight operation  
described below.  
•
“Backlight Operation” is the number of minutes the backlight is turned on per  
hour during the display only (no processing operation) period.  
Important!  
The EL backlight may fail to operate when battery power is low, in order to  
conserve remaining battery power and protect data stored in memory.

PART 1  
Getting Started  
Read this first!  
You must be familiar with the following information in order to use the SF Unit  
correctly. It tells you what to do in order to avoid losing important data stored  
in memory. Please be sure to read the following before using the SF Unit!  
Make back up copies of important data!  
Your SF Unit employs electronic memory, which makes it possible to store  
large volumes of data and to recall stored data quickly and easily. Data is  
retained as long as power is supplied by the batteries. This means that should  
batteries go dead, or if you make a mistake while replacing batteries, the data  
stored in memory may be damaged or lost entirely. Data contents can also be  
damaged or lost due to strong electrostatic charge, strong impact, or extremes  
in temperature and humidity.  
All of this means that you should make back up copies of important data in a  
notebook in case any of the above conditions occur.  
About the “ARE YOU USING.....” and “CLEAR  
MEMORY.....” messages…  
Whenever you turn on the power of the SF Unit, it performs a self-check before  
beginningoperation. Ifaproblemisdiscoveredduringtheself-check, theSFUnit  
displays one of the following messages.  
A
B
Note  
•
The above messages always appear in English, regardless of the system  
language setting.  
13  
PART 1 Getting Started  
If this is the first time you ever turned on the SF Unit…  
Perform the RESET procedure under “Before using the unit for the first time” on  
page 1, starting from step 9.  
If this is not the first time you are using the SF Unit...  
There is probably a problem with the data in memory (data error). Note that once  
data is lost it cannot be recovered. Such data errors are generally caused by one  
of the following problems.  
•
•
Interruption of battery power.  
Severe electrostatic charge, impact, change in temperature, or change in  
humidity.  
•
Hardware problem.  
After a data error is discovered, you will not be able to input or edit data. In order  
to return memory to normal (allowing further input and editing of data), you must  
perform the RESET operation to clear the memory of all data. Before doing so,  
you may want to recall important data and write it down (if you don’t already have  
a copy). You can then re-input the data after clearing the memory.  
The RESET procedure you should use depends on the type of message error  
message on the display.  
“ARE YOU USING A NEW UNIT FOR THE FIRST TIME?”  
1. Make sure that NO is highlighted and then press SET. If YES is highlighted,  
press J to move the highlighting to NO and then press SET.  
•
The message “DATA ERROR! CHECK YOUR USER’S GUIDE FOR PRO-  
CEDURE!” appears on the display at this time. After this message appears,  
you can press CLEAR to clear it from the display and recall data in order to  
make a back-up record of it before continuing.  
2. Press the RESET button, which is located inside the battery compartment  
cover on the back of the unit.  
•
This causes the “CLEAR MEMORY AND SET UP THE UNIT FOR OPERA-  
TION?” message to appear on the display.  
3. PressH tomovethehighlightingtoYES andthenpressSET toresettheunit.  
•
HighlightingNO andpressingSET clearstheresetmessageanddisplaysthe

About the Power Supply  
2. Press SET to reset the unit.  
If you still have trouble after trying the RESET operation, you may have a  
hardware problem. If so, consult with your nearest CASIO dealer.  
General Precautions  
•
•
•
Never try to take the SF Unit apart.  
Avoid strong impact and sudden temperature changes.  
At very low temperatures, the display response time may slow down or the  
display may fail completely. This is temporary and correct operation should  
return at normal temperature.  
•
•
•
To avoid serious damage to the SF Unit caused by leaking batteries, replace  
batteries once every two years, regardless of how much you use the SF Unit  
during that time.  
Never use thinner, benzine or other volatile agents to clean the exterior of the  
SF Unit. Instead, wipe it off with a soft cloth dampened in a solution of water  
and a mild, neutral detergent. Wring the cloth out until it is almost dry.  
If the SF Unit is exposed to strong electrostatic charge, the display may dim  
ortheSFUnitmaylockup.Tocorrectthissituation,switchpoweroff,andthen  
remove and then replace the batteries.  
•
•
Do not press the keys with a pen, pencil or other sharp object.  
The SF Unit may cause interference with radio or television reception. Keep  
it away from such appliances when you are using it.  
•
Note that pressing SHIFT and then LIGHT causes the backlight to light and  
staylitaslongasyoucontinuetooperatetheSFUnit,oruntilyoupressLIGHT  
again to turn it off manually.  
Leaving the backlight on for long periods greatly reduces battery life!  
About the Power Supply  
The SF Unit is powered by three CR2032 lithium batteries. Replace batteries as  
soon as possible after low battery power is indicated by any of the following.  
•
•
•
•
Low battery message appears on the display  
Blank display when power is turned on

PART 1 Getting Started  
Caution  
•
All data stored in memory is lost if you remove more than one battery  
at the same time.  
•
Be sure that you keep a separate copy of all important data that you  
store in the SF Unit.  
Low Battery Message  
A message appears on the display to warn you when the batteries power drops  
below a certain level. Should battery power drop too low, data in memory may be  
corrupted or lost. Whenever a low battery power message appears on the  
display, be sure to stop operation of the SF Unit and replace batteries as soon  
as possible.  
Important!  
Whenever the message “WEAK BATTERIES! CONSULT YOUR USER’S  
GUIDE IMMEDIATELY!” appears, be sure to replace all batteries.  
Battery Precautions  
Incorrectly using batteries can cause them to burst or leak, possibly damaging  
the interior of the SF Unit. Note the following precautions.  
•
Be sure that the positive (+) side of each  
battery is facing up (so you can see it).  
•
Never mix batteries of different types.  
Never mix old batteries and new ones.  
•
16  
About the Power Supply  
•
•
•
Never leave dead batteries in the battery compartment.  
Remove the batteries if you do not plan to use the SF Unit for a long period.  
Replace batteries at least once every year, no matter how much you use the  
SF Unit during that period.  
•
Never try to recharge the batteries supplied  
with the SF Unit.  
•
Do not expose batteries to direct heat, let them  
become shorted, or try to take them apart.  
•
Should a battery leak, clean out the battery compartment of the SF Unit  
immediately, taking care to avoid letting the 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.  
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.

Data Communications  
Data communications capabilities let you transfer data between two CASIO SF  
Units, betweenanSFUnitandaCASIOCSFUnitorNXUnit, orbetweenthisunit  
and a personal computer. You can perform such operations in the Telephone  
Directory, Memo, Schedule Keeper, Calendar, To Do, Expense or Reminder  
modes.  
About data compatibility  
Whenever you exchange data with a CASIO SF Unit, there are certain restric-  
tions concerning data compatibility.  
Send data  
•
You cannot send data to the CASIO SF-A Series Units (SF-A10, etc.).  
Some SF Units, CSF Units, NX Units do not have modes that are included  
with this Unit. For example, some Units do not have a Reminder Mode or an  
Expense Mode. Data from a mode cannot be received by an SF Unit, CSF  
Unit, NXUnitunlessthatSFUnit, CSFUnit, NXUnitalsohasthesamemode.  
Data cannot be sent from this SF unit to a CASIO SF-5580, 5580E, 5590SY,  
5590SYE,5780,5780E,5790SY,5790SYE,5980,5980E,5990SY,5990SYE,  
6500SY, 6700SY, 6900SY, 7100SY or 7200SY unit.  
When data is sent from this SF Unit to a CASIO CSF or NX Unit, data stored  
in Telephone Directory items FREE1 through FREE6 is stored in the  
Telephone Directory MEMO item of the unit to which you are sending data,  
with newline symbols between the FREE items.

When data is sent from this SF Unit to a CASIO CSF or NX Unit, all calendar  
highlighting is blue.  
•
The euro mark can be transferred between two SF-4900ER/SF-4980ER/  
SF-4985ER units. Euro marks are replaced by blank spaces when data is  
transferred from a SF-4900ER/SF-4980ER/SF-4985ER unit to an older  
model.  
Receive data  
•
You cannot receive data from the CASIO SF-A Series Units (SF-A10, etc.).  
•
Some SF Units, CSF Units, NX Units have modes that are not included with  
this unit. Data from such modes cannot be received by this unit.  
The Schedule Keeper of some SF Units is capable of storing multiple-date  
data items. Whenever you transfer such a data item to the your SF Unit, it is  
automatically converted to a single-date data item. The date used is the one  
that starts the original multiple-date data item.  
•
95  
PART 6 Data Communications  
•
•
•
Some SF Unit models have a mark protection feature to protect against  
accidental erasure of data. This unit does not feature mark protection, and so  
such data is received by this unit disregarding the mark protection.  
Data cannot be sent to this SF Unit from a CASIO SF-5580, 5580E, 5590SY,  
5590SYE,5780,5780E,5790SY,5790SYE,5980,5980E,5990SY,5990SYE,  
6500SY, 6700SY, 6900SY, 7100SY or 7200SY unit.  
When data is sent to this SF Unit from a CASIO CSF or NX Unit, CSF/NX  
Telephone Directory MEMO item data is stored in the Telephone Directory  
FREE1 item of this SF Unit.  
•
•
When data is sent to this SF Unit from a CASIO CSF or NX Unit, all text  
becomes monochrome.  
When data is sent to this SF Unit from a CASIO CSF or NX Unit, all calendar  
highlighting becomes monochrome. All CSF/NX calendar dates that are  
orange or green are converted to highlighted dates.  
•
This unit cannot receive PERSONAL, FAMILY, TIMETABLE, or GOLF  
memo data from a CASIO NX Unit.  
Setting Up for Data Communications  
The following describes what you should do to set up for data communications  
between two SF Units, between an SF Unit and a CASIO CSF Unit or NX Unit,  
or between this unit and a personal computer.
