NOTES ON USING THE WATCH

TIME/CALENDAR MODE

[TIME/CALENDAR SETTING]

English

● The calendar automatically adjusts for odd and even months including February of leap years from the

year 1998 up to the end of 2047.

● Once the year, month and date have been set, the day of the week is automatically set.

● The flashing digits except the seconds, the standard time/daylight saving time and the 12-/24-hour

indication move quickly if button C or E is kept pressed.

● Setting the seconds:

• With the second digits flashing, press button C or E in accordance with a time signal. The second
digits are reset to “00”.

• When the seconds read any number from “30” to “59” and button C or E is pressed, one minute
is added and the seconds are reset to “00”.

● If “GREENWICH” is selected for the city, the display to set daylight saving time will not be shown.

● By selecting “ON” for daylight saving time, “ ” mark appears, and one hour is advanced.

● If the watch is left untouched in the TIME/CALENDAR SETTING display with the digits flashing, it will

automatically return to the TIME/CALENDAR mode in 2 to 3 minutes.

● When all the segments light up:

If buttons C and D are pressed at the same time in the TIME/CALENDAR
SETTING display, all the segments of the display will light up as shown
at right. This is not a malfunction.
Press any of the buttons to return to the TIME/CALENDAR mode and
then, set the time/calendar again.

[ADJUSTING THE CONTRAST ON THE DISPLAY]

● The contrast level has been initially set at “10” at the factory.

● When the contrast level is set to “0”, the digits on the display will not

be readable.

22

ALARM MODE

[ALARM TIME SETTING]

● The flashing digits move quickly if button C or E is kept pressed.

● When the time function is displayed in the 24-hour indication, the alarm is also displayed in the 24-hour

indication.

● When setting the hour digits in the 12-hour indication, check that AM/PM is properly set.

● If the watch is left untouched in the ALARM SETTING display with the digits flashing, it will

automatically return to the ALARM mode in 2 to 3 minutes.

[ALARM ENGAGEMENT/DISENGAGEMENT]

● When any one of the alarms is engaged, the alarm mark is displayed.

● At the designated time the alarm rings for 20 seconds. To stop it manually, press any of the buttons.

● The alarm can be tested by keeping buttons C and D pressed at the same time in the TIME/CALENDAR

mode.

STOPWATCH MODE

● After 10 hours have been measured, the stopwatch continues measuring from “00”. If it is left

counting for more than 100 hours, it will automatically be stopped.

● The lap number counts up to “199”. After “199”, the number is displayed in two digits such as “00”

for 200, “01” for 201, and so on.

● Even if the STOPWATCH mode is changed to another while the measurement is in progress, it

continues counting properly. After the stopwatch is used, however, be sure to reset it to prevent the
overconsumption of battery energy that would shorten the battery life.

● Even if the digits are reset to “00” in the stopwatch measurement, the stored data is not erased and

can be recalled unless a new measurement is started.

[MEMORY RECALL FUNCTION]

● In the normal display, the lap number is displayed at the bottom row.

● In the enlarged display, the split time is displayed together with the split number.

● If no measurement is made, “NO DATA” will be displayed when button B is pressed to activate the

English

23

memory recall function.

TIMER MODE

● The timer counts down the set time repeatedly up to 10 times unless stopped.

English

[ADJUSTABLE TIMER SETTING]

● The flashing digits move quickly if button C or E is kept pressed.

● If the watch is left untouched in the ADJUSTABLE TIMER SETTING display with the digits flashing,

it will automatically return to the TIMER mode in 2 to 3 minutes.

WORLD TIME MODE

● In the normal display, the daylight saving time (summer time) mark, country code, time and city mark

are shown. In the enlarged display, the daylight saving time mark is not displayed.

● The time difference and use of daylight saving time may change in some areas or countries when they

are so decided by the countries concerned.

ILLUMINATING LIGHT (Electroluminescent panel)

● The electroluminescent panel loses its luminance as the battery voltage decreases. Also, its

luminance level decreases gradually with use. After 120 hours of use, the level decreases by about
half.

● When the illuminating light becomes dim, replace the battery with a new one. If the illuminating light

remains dim after the battery is replaced, have the electroluminescent panel replaced with a new one
by the retailer from whom the watch was purchased, or an AUTHORIZED SEIKO DEALER. It will be
replaced at cost.

● While the illuminating light is used, the watch gives out a slight noise. However, this is not a

malfunction.

[TURNING ON/OFF OF THE BUTTON OPERATION CONFIRMATION LIGHT]

● This function is deactivated automatically in 11 to 12 hours after it is activated.

24

BATTERY CHANGE

2

Years

● Battery life indicator

When all the digits start flashing, replace the battery with a new one as soon as
possible. Otherwise, the watch will stop operating in 2 to 3 days. We suggest that
you have the battery replaced by a SEIKO DEALER.

* Even though the display is flashing, time accuracy is not affected.

● Necessary procedure after battery change

After the battery is replaced with a new one, or an abnormal display (broken digits,
etc.) appears, follow the procedure below to reset the IC.

Press and hold buttons A, B, C and E at the same time for 2 to 3 seconds.

The miniature battery which powers your watch should last approximately
2 years. However, because the battery is inserted at the factory to check
the function and performance of the watch, its actual life once in your
possession may be less than the specified period. When the battery expires,
be sure to replace it as soon as possible to prevent any malfunction. For
battery replacement, we recommend that you contact an AUTHORIZED
SEIKO DEALER and request SEIKO CR2025 battery.

* The battery life may be less than 2 years if:

• the alarm is used more than once a day,

• the illuminating light is used more than 3 times a day,

• the confirmation sound is used more than 50 times a day.

English

25

* The display will become blank, and the MENU display will appear when the buttons are released.

Then, press button A.

* The display at right will appear.

English

* Before using the watch, set the time/calendar and then the

alarm.

WARNING

● Do not remove the battery from the watch.

● If it is necessary to take out the battery, keep it out of the reach of children. If

a child swallows it, consult a doctor immediately.

CAUTION

● Never short-circuit, heat or otherwise tamper with the battery, and never

expose it to fire. The battery may burst, become very hot or catch fire.

● The battery is not rechargeable. Never attempt to recharge it, as this may cause

battery leakage or damage to the battery.
