• The alarm on indicator (
) and alarm name indicator are displayed for each
alarm (1 through 4, snooze) for which alarm on is selected. The alert on indicator
(
) and alarm name indicator are displayed for each alarm (1 through 4,
snooze) for which alert on is selected.
• In other modes besides the Alarm Mode, the alarm name indicator is displayed for
each alarm for which alarm on is selected.
• In all modes, the alarm on indicator or alert on indicator is shown for any alarm
(ALARM1 through ALARM4, or SNOOZE) that is currently turned on.
To turn the Hourly Time Signal on and off
1. In the Alarm Mode, use D to select the Hourly Time
Signal (SIGNAL).
2. Press A to toggle it on (SIG displayed) and off (SIG
not displayed).
• The Hourly Time Signal on indicator (SIG) is shown on
the display in all modes while this function is turned on.
Data Memory
You can use the watch's data memory to store e-mail
addresses, Web page URLs, and other text data.
Remaining memory
• All of the operations in this section are performed in the
Data Memory Mode, which you enter by pressing C.
Data Memory Records
Each data memory record can contain up to 63
characters. Records are stored in memory in the
sequence they are created.
• The number of records you can store in data memory
depends on the number of characters that make up
each record. See "Data Memory Management" for more
information.
To create a new data memory record
1. In the Data Memory Mode, press A and D at the
same time to display the remaining memory screen.
• You do not have to perform the above step if the
remaining memory screen is already on the display.
• If REST 0% is shown for remaining memory, it means
that memory is full. To store another record, you will
first have to delete some of the records stored in
memory.
2. Press B and the flashing cursor appears on the
Cursor
display, which indicates the setting screen.
3. Use A and D to cycle through characters at the
current cursor location, and C to move the cursor to
the right. See "Inputting Text" for more information.
• If memory becomes full while you are inputting text,
the cursor will jump to the first (leftmost) character of
the text when you press C, instead of advancing to
the right.
4. Press B to store your data and return to the data
memory record screen (without the cursor).
Text
• The message SAVE! appears for about two seconds,
followed by a data memory record screen, which shows
the text you just input in the upper part of the display,
and a record number automatically assigned by the
watch in the lower part of the display.
• While the record number is in the lower part of the
display, you can see only six characters of the text in the
record. You can scroll through the text on the screen by
pressing D. See "To recall data memory records" for
more information.
Record number
To recall data memory records
1. In the Data Memory Mode, press A to scroll forward through data memory records.
• Each press of A advances to the next record and shows its record number and
first six characters of its text.
• Pressing A while the last record in memory is on the display changes to the
remaining memory screen. Pressing A again displays the first record.
2. Press D to scroll through the text on the screen.
First six characters
Pressing D scrolls through the text.
• An end mark indicates the end of the text.
To edit a data memory record
1. In the Data Memory Mode, display the record you want to edit.
2. Press B and the flashing cursor appears on the display.
3. Press C to move the flashing to the character you want to change.
4. Use D and A to change the character.
5. After making the changes you want, press B to store them and return to the data
memory record screen.
To delete a data memory record
1. In the Data Memory Mode, display the record you want to delete.
2. Press B and the flashing cursor appears on the display.
3. Press A and D at the same time to delete the record.
• The message CLEAR! appears to indicate that the record is being deleted. After
the record is deleted, the cursor appears on the display, ready for input.
4. Input data or press B to return to the remaining memory screen.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Features
• If you leave the watch in the Alarm or Data Memory Mode for two or three minutes
without performing any operation, it automatically changes to the Timekeeping
Mode.
• If you leave a screen with flashing digits or a cursor on the display for two or three
minutes without performing any operation, the watch automatically saves anything
you have input up to that point and exits the setting screen.
Data and Setting Scrolling
The A and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Initial Screens
When you enter the Alarm or World Time Mode, the data you were viewing when you
last exited the mode appears first.
Time Calibration Signal Reception
• This watch is able to receive the time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt). Signal reception is
possible within the area represented by a circle with a
radius of about 1000 kilometers.
At distances further than about 500 kilometers, the
signal may become weak and reception may be
impossible under certain conditions.
• Signal reception may be poor in the shaded area on the
map, even though it is within 1,000 kilometers of the
signal transmitter.
Frankfurt
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• This watch is designed to receive the signal transmitted from Mainflingen. This
means that reception is best when the antenna built into the 12 o'clock edge of the
watch is facing towards Mainflingen. Note, however, that moving the watch while the
time calibration signal receive operation is taking place will make stable reception
impossible.
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2039. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2040.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Think of the watch as acting like a TV or radio when it is receiving the calibration
signal. When receiving indoors, move to a location as near as possible to a window.
• Proper signal reception can be difficult or even impossible under the conditions listed
below.
Near TVs, refrigerators, computers, or other household appliances
Far away from broadcasting stations among ferro-concrete structures or near
mountains
Underground, in tunnels or in ferro-concrete buildings
Near high-tension wires, neon signs, or radio stations with interfering frequencies
Near railroads, highways or airports
In trains or cars
• Radio interference can make signal reception impossible.
• Strong electrostatic charge can result in the wrong time being set.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time with the precision noted in "Specifications."
