Charging

the solar

battery

The stopped watch was

exposed to an

adequate light for

longer than “the time

required to fully charge

the watch”, however, it

does not resume its

normal one-second

interval movements.

The amount of exposed light is too

weak.

The time for charging the watch is not

sufficient.

The time required for charging the

watch depends entirely on the amount

of exposed light the watch receives.

Refer to “Guide to charging times” to

charge the watch.

P.35

The built-in IC of the watch has fallen

into an unstable condition.

Refer to “In case of an abnormal

movement” to reset the system.

P.76

Misalignment

of the time

and hand

positions

The watch temporarily

gains or loses time.

The watch has been left in an extremely

high or low temperature place for a long

time.

1. When the watch returns to a normal

temperature, it will display the

precise time as before.

2. If the watch still gains or loses the

time, conduct manual reception if

necessary.

3. If the watch cannot resume normal

movement even after conducting

the above mentioned procedures,

consult the retailer from whom the

watch was purchased.

Misalignment

of the time

and hand

positions

The reception results are

successful, but the precise

time is not displayed.

The watch fails to receive a radio signal

correctly as a result of external

influence. (Incorrect reception)

1. Place the watch where it is able to

receive a radio signal more easily.

2. Conduct manual reception if

necessary.

P.23,

P.56

The hand positions were misaligned as

a result of external influence.

The hands are out of the preliminary

position as a result of external

influence.

P.64

1. The automatic hand position

alignment function will operate, and

these will be corrected. Continue to

use the watch normally. The

automatic hand position alignment

function operates every 12 hours (at

12 AM and 12 PM) for the hour and

minute hands, and every minute for

the seconds hand. If urgent, perform

manual time adjustment.

2. If the watch still gains or loses time,

refer to “In case of an abnormal

movement” to perform procedures.

3. If the watch cannot resume normal

movement even after conducting

the above mentioned procedures,

consult the retailer from whom the

watch was purchased.

P.64,

P.76

The seconds hand position

is not correctly aligned in

“the reception results

display” or “the reception

level display.”

The seconds hand is out of the

preliminary position as a result of

external influence.

Reference

Misalignment

of the time

and hand

positions

The watch displays an

incorrect time hour unit,

even though it displays the

precise time of minutes

and seconds.

The time difference settings are

incorrect.

Check the time difference settings, and

set these to the local region.

P.29

Misalignment

of the date

The reception results are

successful and the precise

time is displayed, but the

date is not correctly

displayed.

The date is out of the preliminary

position.

This happens when the date is out of

the preliminary position as a result of

influence of various external sources or

after the built-in IC is reset.

Set the date to the preliminary position

“1” (the 1st).

P.65

Operation The crown or button

cannot be operated.

The stored electric power is running

short.

Sufficiently charge the watch until it

starts moving at one-second intervals.

P.34

Hands and date are moving right after

a setting is carried out by the crown or

button operation.

Wait without doing anything.

After the date stops, the crown and

button can be operated.
