To improve radio wave reception
・ Move the watch to a diff erent place or try rotating the watch to change its orientation.
E ven if the watch is within the radio wave reception range, radio reception may be obstructed depending on conditions such as weather,
surrounding geographic features, buildings or direction. Refer to "Environments in which it is diffi cult to receive a radio signal" on P124.
If the watch is located outside the reception range, it cannot receive radio waves. → Radio signal reception range P118
・ If the home time city is not adequately designated, the watch cannot receive radio waves.
Check the home time city setting.
→ How to check the settings of the watch (Miscellaneous information display) P110
・ Try receiving radio waves at a diff erent time of the day. (Manual reception)
E ven in the same location, the radio wave reception environment changes
depending on the time of the day. Radio wave reception is generally easier at night.
・ When you see an Out Of Service message on the screen during manual reception
Y ou will see this message if the designated home time city is outside the radio wave reception range. Check the
home time city setting.

T he watch can receive radio waves only when the home time city is designated for a city, such as Tokyo, within a radio wave reception range
in which the radio wave reception function works.

How to manually set the time and date (Year, month and date)
When you use the watch continuously
outside the reception range or in a place or
region where the watch cannot receive radio
waves, manually set the time and date.
→ "Radio signal reception range" P118
・ W hen you start using the watch in a radio wave
receivable environment, let the watch receive
radio waves so that it can set the time and date.
→ A utomatic reception and manual
reception P117
※ W hen the watch sets the time and date after it
successfully received radio waves, you do not
have to manually adjust the time and date.
※ E ven if the watch cannot receive radio waves, its

accuracy is kept by the quartz movement with
monthly accuracy within 15 seconds.
※ I f the watch receives radio waves after the time
and date were manually set, it will indicate the
time and date obtained by the reception.

■ Radio wave reception Q & A
Q ： When will my watch receive radio waves?
A ： S tandard radio waves are transmitted almost 24 hours a day. But your radio-controlled watch does
not receive radio waves all day. The watch is designed to conduct automatic reception a few times
at midnight when radio waves are generally stronger. While the watch is not receiving radio waves,
its accuracy is kept by the quartz movement with monthly accuracy within 15 seconds.
Q ： M y watch does not correct time immediately after manual reception. Why does this happen?
A ： It may take 17 minutes at the longest for your watch to complete receiving radio waves.
It takes one minute in each instance for complete time and calendar data to be transmitted. In order
to synchronize, the watch must receive an entire sequence of data. As reception interference often
occurs due to various sources such as radio noise, the watch is designed to repeat receiving radio
waves several times to verify correct data. Therefore, it takes some time for the watch to complete a
reception. Additionally, a poor reception environment may prolong the duration of reception. While the
watch is receiving radio waves, remember not to operate any buttons and keep your watch stationary.
Q ： What should I do for successful reception?
A ： T he strength of standard radio waves is aff ected by various factors such as distance from the
transmitting station, surrounding geographical features including nearby buildings, or weather
conditions. As the watch is designed to conduct automatic reception at midnight, it is a good idea
to place the watch by a window facing the direction of the transmitting station before you go to
bed. When you conduct manual reception, try looking for a place with a good reception environment.
