■ Power Supply
Your Digital Diary is powered by two AAA-size batteries, and its memory is protected by a single
CR2032 lithium battery.
Low battery Warning
The message, “MAIN BATTERIES WEAK! REPLACE THEM! UNIT WILL NOT TURN ON AGAIN!”
appears when battery power is low. Replace the main batteries immediately after this message appears. After replacement of the main batteries, execute RESEToperation. (refer to 4 page)
Important!
• After the low battery message appears on the display, the unit automatically turns off in about 10
seconds and will not turn back on again until you replace batteries.
• Never replace main batteries while the Digital Diary is turned on (while there are figures on the
display).
• There is not low battery warning for the back-up battery. Be sure to replace the back-up battery
once every 5 years.
• Be sure you keep a separate copy of all important data that you store in the Digital Diary.
Battery Precautions
Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the Digital
Diary. Note the following precautions.
•
•
•
•
•
•
•
Be sure that the positive (+) side of each battery is facing in the correct directions.
Never mix batteries of different types.
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 batteries if you do not play to use the unit for a long time.
Replace batteries at least once every five years, no matter how much you use the unit during that
period.
• Never try to recharge the batteries that come with the unit.
• Should a battery leak, clean out the battery compartment of the 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.

3. DATA COMMUNICATIONS
You can transfer data between two CASIO SF-5580E,SF-5780E, or SF-5980E units, or between your
Digital Diary and a personal computer only. You cannot exchange data with any other CASIO Digital
Diary model. Data communications can be performed while in the Telephone Directory, Memo, Schedule
Keeper, Calender, To Do, Reminder, or Expense Manager Mode.
■ Setting Up for Data Communications
The following describes what you would do to set up for data communications between two Digital
Diary units or between a Digital Diary unit and a personal computer.
To connect to another Digital Diary unit
1. Make sure that the power of both units is turned off.
2. Remove the covers from the data communications jacks on the two Digital Diary units.
3. Connect the two units using the SB-62 cable.
SB-62 cable
Important!
• Be sure to replace the connector covers on the Digital Diary units when you are not perfoming data
communications.
Performing data communications between a Digital Diary unit and a personal computer
You must purchase an optional CASIO Data Communication Package in order to perform data communication between your Digital Diary unit and a personal computer. Please note that there are a
number of different CASIO Data Communication packages to suit various computers and Digital Diary
types. Because of this, you should note the following important points when purchasing a Data Communication Package. If you have any question about which package you need, consult with a expert.
• Make sure the Data Communication Package (FA-127) is designed for you with your particular
model of personal computer.
• For information on how to connect the Digital Diary to a personal computer, see the user’s manual
that comes with the Data Communication Package (FA-127).
■ REMARK: FA-127 is the Personal Computer Link (software and cable unit) for Windows.
