Transmitters
The time calibration signal received by this watch depends on the currently selected
Home City.
When a U.S. time zone is selected, the watch receives the time calibration signal •
transmitted from the United States (Fort Collins).
When a Japanese time zone is selected, the watch receives the time calibration •
signals transmitted from Japan (Fukushima and Fukuoka/Saga).
When a European time zone is selected, the watch receives the time calibration •
signals transmitted from Germany (Mainflingen) and England (Anthorn).
When a China time zone is selected, the watch receives the time calibration signal •
transmitted from China (Shangqiu City).
When your Home City is • LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW
(which can receive both the Anthorn and Mainflingen signals), the watch first tries
to pick up the signal it last received successfully. If that fails, it tries the other signal.
For the first receive after you select your Home City, the watch tries the nearest
signal first (Anthorn for LIS, LON, Mainflingen for MAD, PAR, ROM, BER, STO,
ATH, and MOW).
Auto Return Features
If you leave the watch with a flashing setting on the display for two or three minutes •
without performing any operation, the watch will exit the setting mode automatically.
The watch will return to the Timekeeping Mode automatically if you do not perform •
any operation for two or three minutes in the Alarm Mode.
High-Speed Movement
The • D and B buttons are used to change the hand setting in various setting
modes. In most cases, holding down these buttons will start high-speed movement
of the applicable hand(s).
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing
when you last exited the screen will appear first.
Timekeeping
Resetting the seconds to • 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
The year can be set in the range of 2000 to 2099. •
The watch’s built-in full automatic calendar makes allowances for different month •
lengths and leap years. Once you set the date, there should be no reason to
change it except when battery power drops to Level 5 (C: Charge).
The current time for all city codes in the Timekeeping Mode and World Time Mode •
is calculated in accordance with the Coordinated Universal Time (UTC) for each
city, based on your Home City time setting.
Illumination Precautions
Illumination may be hard to see when viewed under direct sunlight. •
Illumination turns off automatically whenever an alarm sounds. •
Frequent use of illumination runs down the battery. •
Auto light switch precautions
Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light •
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
Illumination may not turn on if the face of the watch is more •
than 15 degrees above or below parallel. Make sure that the
back of your hand is parallel to the ground.
Illumination turns off in about one second, even if you keep •
the watch pointed towards your face.
Static electricity or magnetic force can interfere with proper •
operation of the auto light switch. If illumination does not
turn on, try moving the watch back to the starting position
(parallel with the ground) and then tilt it back toward you
again. If this does not work, drop your arm all the way down
so it hangs at your side, and then bring it back up again.
Under certain conditions, illumination may not turn on until about one second after •
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the auto light switch.
You may notice a very faint clicking sound coming from the watch when it is shaken •
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.

Approximate battery operating time: 6 months (from full charge to Level 5 (C:
Charge)) under the following conditions:
– Watch not exposed to light
– Internal timekeeping
– Display on 18 hours per day, sleep state 6 hours per day
– 1 illumination operation (1.5 seconds) per day
– 10 seconds of alarm operation per day
– 4 minutes of signal reception per day
Frequent use of illumination runs down the battery. Particular care is required when
using the auto light switch.
