RADIO WAVE CONTROLLED WATCH

 About this radio wave controlled watch

 

This watch receives calibration signal and automatically updates the 
time and date.

○ 

Transmitter

 

GERMANY

 

Signal code :  DCF77

 

Location: 

Mainflingen Germany (located 25 Km southeast of 
Frankfurt)

 

U.K

 

Signal code :  MSF

 

Location : 

Rugby city (located near from London)

 

U.S.A

 

Signal code :  WWVB

 

Location : 

FortCollins in Colorado (located 100Km north of 
Denver)

 

JAPAN

 

Signal code :  JJY

 

Location : 

Mt.Haganeyama (located 45Km southwest of 
Fukuoka)

 

The signal usually operates 24 hours of a day, but it may be 
temporarily interrupted for maintenance and lightning 
cuntermeasure.

○ 

Radio wave reception zone

 

This watch can receive radio waves within a radius of about 
1,000km from the standard radio wave station. However, the 
coverage can vary depending on time, season, weather conditions, 
local environmental conditions, etc.

Which way to point the watch during reception

Radio 
wave 
station

Antenna

Flatten the wristband so it doesn't curl 
under the antenna.

*  The indicated reception area is for your reference only. Sometimes you cannot receive radio waves 

even within the zone shown in the figure.

 How to successfully receive radio waves

•  It may be difficult to receive radio waves when metal shielding blocks the watch. 

When inside a ferroconcrete building etc., try to place the watch near a window 
that is as close as possible to facing the radio wave station.

•  Try not to move the watch during radio wave reception.
•  Good reception can be achieved if you aim the reception antenna (on the upper 

side of the watch) toward the radio wave station.

•  You can check signal strength by looking at the reception icon that is displayed 

during radio wave reception. If you find a place and a direction to aim the watch in 
advance that has stable reception, that will help to get a good connection.

* The watch may fail to receive radio waves or may receive them inaccurately near 

(within 10km from) the standard radio wave station. In this case, change the 
direction of the antenna by 45 - 90 degrees or receive radio waves again at a 
place far (10km or farther) from the standard wave station.

* Sometimes when the watch indicates strong radio wave reception, it still may not 

be able to receive a signal due to surrounding environmental interference such as 
electrical noise.

* The maximum time required to receive a complete signal can be up to 13 minutes. 

It may change depending on distance from the standard radio wave station, time, 
season, weather, etc.

○ 

Places where it may be difficult to receive radio waves

•  Places with extremely high or low temperatures.
•  Inside ferroconcrete buildings, underground, inside high-rise buildings, in valleys 

between mountains, etc.

•  Inside vehicles, trains, and airplanes.
•  Places that tend to have electrical noise such as near high voltage cables, electric 

train cables, and near airports.

•  Near home appliances such as televisions, refrigerators, computers, fax machines, 

inverter fluorescent lights, OA machines, and operating cellular phones.

* The watch operates using its built-in quartz accuracy under conditions of poor 

reception. When it returns to a reception area and receives radio waves, the watch 
displays the correct time. The watch operates using its built-in quartz accuracy 
between signal reception cycles.

AUTOMATIC RECEPTION

If you receive radio waves properly, the time and date are adjusted automatically.

• The watch automatically receives radio waves a maximum of two times a day.

• If one of the two reception attempts is successful, automatic reception won't be 

attempted again until the next day.

  During the daylight saving time (hereinafter, referred to as the DST) period, the 

watch receives radio waves at 3:05AM and 4:05AM. If the watch receives the radio 
waves normally, it automatically displays the SUM. If it receives the radio waves 
normally after the DST period, it automatically displays the ordinary time.

• Since the DST is automatically corrected, you do not need to correct it, as long as 

the watch receives radio waves. In a district where the DST is not applied, 
however, you are required to correct the DST manually.

SUMMER TIME : 3:05AM, 4:05AM

WINTER TIME :   2:05AM, 3:05AM
