2. OPERATION CHART : QW-1805
About the backlight
In any mode, press
to illuminate the display for about three seconds.
In the Timekeeping Mode, animated figures appear in the animation area whenever
the backlight is turned on.
The backlight of the watch employs an electro-luminescent (EL) light, which loses
illuminating power after very long use.
The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
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.
The backlight automatically turns off whenever an alarm sounds.
About animated figures
The following are the animated figures that appear in each mode.
Rotating Globe
This figure appears after you have been in the Timekeeping Mode
or World Time Mode. Occasionally an airplane or a flying saucer
appears.
Dances of the World
Dancing figures appear whenever you press
or
in the Time-
keeping Mode. There are two dances for each day of the week.
However, the dance for another day of the week may appear.
Ostrich
The ostrich appears whenever you are in the Stopwatch Mode,
and runs while a stopwatch timing operation is being performed.
Alarm Clock
This figure appears whenever an alarm time is reached in any
mode except the Stopwatch Mode.
WORLD TIME MODE
The World Time Mode shows the current time in 40 cities
(27 time zones) around the world.
The time settings of the Timekeeping Mode and the
World Time Mode are independent, so you must make
separate settings for each. Note, however, that the sec-
onds counts for both modes are synchronized with each
other.
Whenever you change the time setting for any city in
the World Time Mode, the settings of all other cities are
changed accordingly.
The 12-hour/24-hour format of the World Time matches
the format you select in the Timekeeping Mode.
The time zone that is displayed when you leave the World
Time Mode will still be displayed when you enter the
World Time Mode again.
To view the time in another zone
While in the World Time Mode, press
to scroll forward through the city codes (time
zones) and
to scroll back.
For full information on city codes, see the "CITY CODE TABLE" at the back of this
manual.
Holding down either button scrolls through the city codes at high speed.

Holding down either button while the hour or minutes digits are selected changes
the setting at high speed.
5. After you set the time, press
to return to the World Time Mode.
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 World Time Mode automatically.
TIMEKEEPING MODE
Use the Timekeeping Mode to set the current time and date. You can view the cur-
rent time in the zone (city) you select in the World Time Mode.

Holding down either button changes the current selection at high speed.
With the 12-hour format, the P (PM) indicator appears to the left of the hour digits
for times in the range of noon to 11:59 pm and the A (AM) indicator appears to the
left of the hour digits for times in the range of midnight to 11:59 am.
With the 24-hour format, times are indicated in the range of 00:00 to 23:59, without
any indicator.
