● The battery used in this watch is a rechargeable battery, which is different from
ordinary silver oxide batteries. Unlike other disposable batteries such as drycell batteries or button cells, this rechargeable battery can be used over and
over again by repeating the cycles of discharging and recharging.
● The capacity or recharging efficiency of the rechargeable battery may gradually
deteriorate for various reasons such as long-term use or usage conditions.
Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the efficiency of the rechargeable battery decreases, it will
be necessary to have the watch repaired.
● When the secondar y batter y is fully charged, the overcharge prevention
function is automatically activated to avoid further charging.

HOW TO CORRECT THE PRELIMINARY POSITIONS
When the watch is unable to display the precise time, date or day even if it
successfully receives a radio signal, the preliminary positions may be misaligned.
The preliminary positions may be misaligned due to the following reasons:
• In the case of a strong impact : Misalignment may occur when dropping or hitting the watch.
• In the case of a magnetic influence : Misalignment may occur when bringing the watch close to
an object which generates magnetism.
■■ SETTING THE PRELIMINARY POSITIONS OF THE DATE, DAY HAND, HOUR
AND MINUTE HANDS
■ Automatic Hand Position Adjustment Function (Function to automatically
adjust the preliminary positions of the hour and minute hands)
The hour, minute, and second hands have an "Automatic Hand Position Adjustment Function,"
which automatically corrects an incorrect preliminary position. It activates once a minute for the
second hand and at 12:00 both for the AM and PM for the hour and minute hands.
* This function works when the preliminary positions are misaligned due to external factors
such as strong impact or magnetic influence. It does not work to adjust accuracy of the watch
or slight deviations which may occur during the manufacturing process.
* The preliminary positions of the hour and minute hands can also be manually adjusted. P.43
■ Setting the Preliminary Positions of the Date and the Day
Since the preliminary positions of the date and the day are not automatically adjusted, it must
be adjusted manually. P.43
42
English
PRELIMINARY POSITIONS
The preliminary position of the date is
the “1st.”
The preliminary position of the day hand
is “S.”(Sunday)
The preliminary positions of the hour and
minute hands are “0:00 AM.”
When the preliminary positions are incorrect, the correct date, day of the week or
time cannot be displayed even if the watch receives radio signals.
In such a case, by correcting the preliminar y positions, wrong date or day
indication, loss or gain of the time can be corrected.
When the numerical number of the date is not located at the center of the window,
it can be corrected by the same procedures as mentioned above.
To correct the preliminary positions, perform the operation on the next page.
