Chapter 16 Technical Reference
100 alarms are already set!
Cause: The maximum allowable
limit of 100 alarms are already set. Action: Wait until some of the existing alarms are used, or delete
alarms you do not need to make
room for new ones.
Cause: You are trying to highlight
dates for a period that spans multiple
years.
Action: The range of dates when
specifying highlights must be within
one single year. Change your date
range specification so it is within the
same year.
All dates you select must be within the same year.
Cause: Battery power is getting
weak. Action: Replace batteries as explained on page 19 of this User’s Guide.
Batteries are getting weak! Replace them as instructed in the User’s Guide.
Cause: An alarm time has been
reached for secret memory area data. Action: Enter the secret memory area to view details about the alarm.
Check the secret memory area!
Cause: This message appears after
an operation that can affect your
time settings.
Action: Since all alarms and other
timekeeping related operations are
based on your time setting, be sure
to check it and make corrections as
necessary whenever this message
appears.
Check your home time setting and correct it if necessary!
Message Table
Cause: Some of the cells in a range
you are deleting in the Pocket Sheet
Mode contain data.
Action: Press Yes to delete the cells
and the data they contain, or press
No to close the dialog box without
deleting anything.
Cells in the range you are deleting contain data.
Delete them anyway?

184
Data error! Consult your User’s Guide for correct procedure.
Cause: An internal data error has
corrupted memory data. Action: See page 15 of this User’s Guide for the correct procedure.
Cause: A data error requires that
you perform the RESET operation,
which deletes all data stored in
memory and returns all settings to
their initial defaults.
Action: Tap Yes to close the dialog
box. You can then recall data stored
in memory to make written copies
before it is cleared by the RESET
operation. Tap No to go immediately
into to the RESET operation, which
will delete all data stored in memory.
Data error! Do you want to view data before resetting?
Cause: None of the data in memory
matches the characters you specified
for a search operation.
Action: Check the characters you
specified to make sure you did not
make a mistake, or try searching for
different characters.
Data item not found!
Cause: You did not input all of the
minimum data required to store the
data item.
Action: Input the minimum required
entries for the mode where you are
inputting new data. Check the
minimum requirements and input the
required data.
Input all required data.
Cause: An error occurred during
data communication. Action: Correct the cause of the error and try again.
Communication error!

185
Chapter 16 Technical Reference
Memory is full!
Cause: You are trying to input data
or receive data while memory is
already full.
Action: First try performing the
memory management operation to
see if more memory can be made
available. If this message still
appears, it means that memory is
really full. Delete data you no longer
need to make room for more data.
Cause: The time you are trying to
set for an alarm is already passed. Action: This is merely a warning message that appears for about one
second. After that, the dialog box
closes and the data is stored without
the alarm.
That alarm time is already passed!
Cause: The time you are setting for
an alarm is already used. Action: Change the alarm time to one that is not yet used.
That alarm time is already used!
Cause: You are trying to use invalid
values for a date. Action: Input the date correctly.
Make sure you are inputting the date correctly.
Cause: You are inputting invalid
values for a time setting. Action: Input proper values for the time.
Make sure you are inputting the time correctly.
Cause: The sheet you are working
with in the Pocket Sheet Mode is
larger than the allowable maximum.
Action: Reduce the amount of data
contained in the sheet or divide the
data between two or more sheets.
Sheet is too big!

186
The reset operation deletes all data in memory!
Do you want to continue?
Cause: You are about to perform the
RESET operation, which deletes all
data stored in memory and returns
all settings to their initial defaults.
Action: Tap Yes to perform the
RESET operation and delete all data,
or No to close the dialog box
without deleting anything.
Cause: You are specifying a
Reminder date that is outside the
period specified by the start date and
end date.
Action: Check the specified period
and set the date correctly.
That date is outside of the specified period.
That name is already used!
Cause: You are trying to assign a
name that is already used when
naming a payment type or expense
type.
Action: Use a different name.
The next step starts data deletion and unit reset!
Do you want to continue?
Cause: This is the final warning
before execution of the RESET
operation, which deletes all data
stored in memory and returns all
settings to their initial defaults.
Action: Tap Yes to execute the
RESET operation and delete all data,
or No to close the dialog box
without deleting anything.
This operation will push some data outside the sheet.
Continue?
Cause: The Pocket Sheet Mode
operation you are performing will
cause some of the cells of the sheet
to be pushed outside the range of the
sheet. This causes the data in the
