Adjusting Home Positions
Strong magnetism or impact can cause the hands of the watch to be off. If this
happens, perform the applicable home position adjustment procedures in this section.
Hand home position adjustment is not required if the analog time and digital time are
the same in the Timekeeping Mode.
To adjust home positions
1. In the Timekeeping Mode, hold down A for about five seconds. You can release the
button after “H.SET” appears on the display.
Though “ADJ” will appear on the display after about two seconds, do not release
the button yet. Keep it depressed until “H.SET” appears.
E-43
Correct hour and
minute hand positions
The hour and minute hands should move to 12 o’clock
(their home position), and “0:00” will flash on the
display.
If the hour and minute hands are not at 12 o’clock,
use D (+) and B (–) to move them there.
Holding down either button will cause the hands to
move at high speed. Once started, high-speed hand
movement will continue even if you release the button.
To stop high-speed hand movement, press any button.
High-speed hand movement started with the D (+)
button will stop automatically after 12 revolutions of
the minute hand. If started with the B (–) button, it
will stop after one revolution of the minute hand.
2. After everything is the way you want, press A to return to the Timekeeping Mode.
After performing home position adjustment, enter the Timekeeping Mode and check
to make sure that the analog hands and the digital display indicate the same time. If
they do not, perform home position adjustment again.

Timekeeping
Resetting the seconds to 00while 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 after you have the watch’s battery replaced or when battery power drops to
Level 5.
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 automatically dims if it is lit and an alarm or time up alarm sounds.
Frequent use of illumination runs down the battery.
