TIMEKEEPING MODE
In addition to normal timekeeping, the Timekeeping
Mode is also used to set the current time and
date. You can also adjust the seconds count to
"00" at any time by pressing two buttons.
To adjust the seconds count to "00"
In the Timekeeping Mode, press B and C
simultaneously to adjust the seconds count to
00.
· If you press B and C at the same time while
the seconds count is in the range of 30 to 59, the
seconds are reset to 00 and 1 is added to the
minutes. If the seconds count is in the range of
00 to 29, the minutes count is unchanged.
To set the time and date
1. Hold down A while in the Timekeeping Mode until the seconds digits start
to flash on the display. The seconds flash because they are
selected.
· While the seconds digits are selected (flashing), press C to reset the
seconds to 00.
2. Press M to change the selection in the following sequence.
3. While any other digits (besides seconds) are selected (flashing), press C
to increase the number or B to decrease it. Holding down either button
changes the current selection at high speed.
· While any digits are selected, press L to switch between the 12-hour and
24-hour formats.
· When the 12-hour format is selected, the 12H indicator appears in place
of the day of the week in the text area of the display. With the 12-hour
format, the P indicator appears on the display to indicate "p.m." times.
There is no indicator for "a.m." times.
Selecting the 24-hour format causes the 24H indicator to appear in place
of the day of the week in the text area, and the 24 indicator to appear on the
display.
4. After you set the time and date, press A to return to the Timekeeping
Mode.
· The day of the week is automatically set in accordance with the date.
· The date can be set within the range of January 1, 1995 to December 31,
2039.
· If you do not operate any button for a few minutes while a selection is
flashing, the flashing stops and the watch goes back to the Timekeeping
Mode automatically.
About the backlight
Press L to illuminate the display for about two seconds. While Morse code
data is on the display in the Morse Code Mode, pressing L does not
illuminate the display.
Notes
· The backlight of the watch employs an electro-luminescent (EL) light, which
loses illuminating power after very long use.
· The backlight remains lit for about two seconds from the point you press
L , even if it already lit when you press L . If you keep L depressed for
one or two minutes, the backlight will automatically turn off.
· The illumination provided by the backlight may be hard to see when viewed
under direct sunlight.

· The backlight automatically stops illuminating whenever an alarm sounds.
· The watch will emit an audible sound whenever the display is illuminated.
This is caused by a transistor that vibrates when the EL panel lights up. It
does not indicate malfunction of the watch.
CONTACT CODE MODE
The Contact Code Mode lets you store up to
100* sets of contact data (such as telephone
numbers). Stored data is sorted automatically
into alphabetic sequence based on the text
area text.
* The Contact Code Mode shares memory with
the Mission Code Mode. This means that the
maximum number of Contact Code Mode
entries you can store is reduced by one each
time you store a Mission Code Mode data
item.
· Whenever you enter the Contact Code Mode,
the text CONTACT CODE scrolls across
the text area of the display once. Next, contact
code data appears on the display. You can
interrupt scrolling of the initial text and
immediately display contact code data at any
time by pressing A , B , or C .
· See the "CHARACTER LIST" at the back of this manual for details on how
the watch sorts data.
· The data item that appears on the display when you enter the Contact Code
Mode is the same one that was displayed the last time you exited the
Contact Code Mode.

the same time to display the new data display.
· If there is no contact code data stored in memory
yet, the new data display appears as soon as
you enter the Contact Code Mode.
· If the message FULL appears in the text area
of the display, it means that memory is full. To
store more data, you will first have to delete
some of the data stored in memory.
2. Hold down A until the flashing cursor appears in the text area of the
display.
3. Input a name in the text area and a contact number in the number area.
· You can input up to eight characters in the text area, and 12 digits in the
number area.
· You can input only hyphens, numbers and spaces in the number area (you
cannot input text).
Use B and C to input characters, and M to move the cursor around the
display. For details, see "INPUTTING TEXT".
4. After inputting your data, press A to store it and return to the Contact
Code Mode.
· When you press A to store data, the message SORT appears on the
display for a few seconds. After the sort operation is complete, the normal
Contact Code Mode display (without the cursor) appears.
