■ Make sure to keep the watch sufficiently charged
The watch operates while charging electricity by converting light
received on the dial to electrical energy. It cannot properly operate
unless the remaining energy is sufficient. Place or store in a location
receiving light, etc., to sufficiently charge electricity.
■ T he amount of energy stored in the watch can be checked by the
movement of the second hand.

Features
1
This solar-drive and radio-controlled watch is equipped with a radio signal adjustment function.
・ T he watch is operated by using electric energy which is converted from the light
received by the solar panel.
・ T his watch displays the precise time by receiving radio signals conveying time information.
It can receive official standard frequencies from Japan (from either of two transmitting
stations), the People's Republic of China, the United States of America and Germany.
■ Radio Signal Receiving Function ・・・・・・・・・
T his watch adjusts the time and the date precisely by automatically
→ P.98
receiving radio signals daily.
I n addition, radio signals can be forcibly received with manual operation.
T his watch can receive official standard radio signals from Japan (from
2 transmitting stations), China, U.S.A. and Germany (the transmitting
station for receiving radio signals can be selected using the time
difference adjustment function).
■ Display Function of Radio Signal Reception Level ・・・
The movement of the second hand indicates the radio signal reception
→ P.138
level during radio signal reception attempts. (only manual reception)
■ Display Function of Radio Signal Reception Results ・・・
The movement of the second hand indicates radio signal reception
→ P.108
results (Yes/No).

■ To receive radio signals
The watch automatically receives radio signals to adjust the time
every day.
Automatic radio signal reception is carried out before two and four
o'clock during the night.
During this period of time, place the watch in a location that easily
receives radio signals without wearing it and do not move it.
→ To improve Radio Signal Reception P.105
■ Time Difference Adjustment Function ・・・
This watch can display local time around the world by
(Selecting Transmitting Station)
setting the appropriate time difference. In addition,
→ P.114
setting the time difference enables the watch to
receive official standard radio signals to set the time
if the watch is worn in a radio signal reception range.
■ Solar Charging Function ・・・・・・・・・・・・・
A solar cell underneath the dial converts any form of
→ P.110
light into electrical energy to charge it. Once fully
charged, the watch continues to run for approximately
six months.
■ Energy Depletion Forewarning Function ・・・
The movement of the second hand indicates that the
→ P.112
battery should be charged.
■ Power Save Function ・・・・・・・・・・・・・・・・・・
This watch is equipped with a function which can
→ P.113
suppress energy consumption when it is left without
receiving an adequate light source for a certain
length of time.
■ Automatic Hand Position Alignment Function ・・・
When the hand positions display an incorrect time as
→ P.144
a result of external influences such as magnetism, the
watch automatically corrects the hand misalignment.
