Solar Charging

Your watch runs on electrical power generated from light, which is stored by a chargeable battery. To ensure stable operation, make sure that the watch is exposed to light as much as possible.

• Whenever you are not wearing the watch on your wrist, position it so the face (solar cell) is pointed in the direction of a source of bright light.

Solar cell

Leave the watch under fluorescent lighting, near a window, etc.

• When wearing the watch, try to keep your clothing from blocking its face, where the solar cell is located.

Charging efficiency is reduced significantly even if the face of the watch is covered only partially by your sleeve.

If you use the alarm, calibration signal receive, or any other function that puts a large load on the battery, the hands will stop. At this time the following operations are disabled in order to allow battery power to recover.

• Stopwatch elapsed timekeeping

• Alarm beeper

• Time calibration signal reception

Normal operation will return after the battery recovers.

Low Battery Alert

When secondary battery power is low, the second hand of the watch will jump at 2-second intervals to let you know that charging is required.

• Even if the battery level drops to the point that timekeeping stops, you still will be able to recharge the battery and use the watch again.

• When you recharge the battery after it drops to a level where timekeeping stops, the hands will move automatically to the current time setting.

• Try to keep the watch exposed to light as much as possible during normal use.

Charging Precautions

Avoid charging the watch in the following locations, and anywhere else where it may become very hot.

• On the dashboard of an automobile parked in the sun

• Very close to an incandescent light source or other sources

How a Radio-controlled Watch Works

What is a radio-controlled watch?

A radio-controlled watch is designed to receive a time calibration signal that contains standard time data and adjust its current time setting accordingly.

Transmitter

Cesium

atomic clock

After the watch receives the Standard Time signal, it performs internal calculations to determine the current time. Because of this, there may be an error of up to one second in the displayed time.

Long-wave time

Watch

Reception Time

A receive operation can take anywhere from about two to seven minutes.

• Under certain conditions, a receive operation can take as long as 13 minutes.

Positioning the Watch for Best Reception

Remove the watch from your wrist and place it somewhere so its top (12 o’clock side, where the antenna is located) is facing approximately in the direction of the signal transmitter. Keep the watch away from metal objects.

Calibration Signal

• The Japanese calibration signal (Call Sign: JJY) is maintained by the National Institute of Information and Communications Technology (NICT). It is transmitted 24 hours a day from the Mt. Otakadoya transmitter (40 kHz) located in Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane transmitter (60 kHz) located on the border between Saga Prefecture and Fukuoka Prefecture.

• The U.S. calibration signal (Call Sign: WWVB) is transmitted by the National Institute of Standards and technology from Fort Collins, Colorado.

• The U.K. calibration signal (Call Sign: MSF) is transmitted by the National Physical Laboratory (NPL) from Anthorn, which is located near Anthorn, Cumbria.

• The German calibration signal (Call Sign: DCF77) is transmitted by Physikalisch - Technische Bundesanstalt (PTB) in Mainflingen, which is located southeast of Frankfurt.

• Time calibration signal frequencies and transmitter locations are subject to change.

The time data of the Japanese calibration signal (Call Sign: JJY) is maintained by the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT). Note that transmission of the calibration signal may be interrupted occasionally due to maintenance, lightning, etc. For more information, visit the website of the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT) at the following URL.

http://jjy.nict.go.jp

• Note that the above URL is subject to change.

Important!

Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception.

• You should think of your watch as operating like a radio or TV when it is receiving the calibration signal.

Among or near buildings

Near high-voltage lines

Inside an automobile, train, plane, or other vehicle

Reception Ranges

The table below shows the time calibration signal that the watch receives when a particular city code is selected as your Home City.

••

• For information about Home City settings, see “Configuring

••

Home City Settings”. See the “City Code List” for information about city codes.

Home City

(Supports signal reception)

TYO, HKG

HNL, ANC, LAX,

DEN, CHI, NYC

LON, PAR, ATH

• Signal reception is possible in the time zones represented by HKG (Hong Kong), HNL (Honolulu), and ANC (Anchorage) when reception conditions are good.

• Certain conditions can make reception impossible even when the watch is within one of the reception ranges shown above. Signals become weaker outside of the smaller circles indicated by dashed lines in the nearby maps, so the reception environment has a greater effect on signal reception.

• The following also can affect signal reception: geographic contours, structures, weather, climate, time of day (afternoon, evening), noise.

Receivable Transmitter

Japan (JJY)

United States (WWVB)

U.K. (MSF) and Germany (DCF77)

Auto Receive

Getting Ready for Auto Receive

You will need to perform the operations described below in order to use Auto Receive.

• Configure the Home City setting of the Timekeeping Mode so it matches your current location. The Home City must be in a time zone where calibration signal reception is supported. See: “Reception Ranges” and “Configuring Home City Settings”.

• Put the watch into the Timekeeping Mode or World Time Mode. See: “Modes and Indicators”.

• During the Auto Receive times, position the watch correctly for best reception. See: “Auto Receive Start Times” (below) and “Positioning the Watch for Best Reception”.

How Auto Receive Works

Calibration signal reception will start automatically whenever the current time in the Timekeeping Mode reaches one of the Auto Receive Start Times listed below. Auto receive can be performed up to six times a day, but any time a signal receive operation is successful, no more auto receive operations are performed that day. Note that the Auto Receive Start Times differ according to the current Home City setting and the summer time setting.

• Summer time, or Daylight Saving Time (DST) as it is called in some countries, calls for setting clocks ahead one hour from standard time during the summer season.

• Note that the start and end of summer time, and whether summer time is used at all depends on each country.

Resin band

Metal band

• Orienting the watch so it is sideways to the transmitter makes it more difficult for the watch to receive the signal.

• Do not move the watch while it is receiving the calibration signal.

Next to a TV, speaker, fax, computer, cellphone, or other household appliances or office equipment

If you are experiencing problems with reception, move away from the types of locations described above to a location with better reception, and try again.

At a construction site, airport, or other location where there is radio interference

Near mountains

Receiving a Calibration Signal

There are two methods you can use in order to receive the time calibration signal.

• Auto Receive up to six times per day

• Manual Receive where you hold down the A button in the

Timekeeping Mode.
