1. Your Watch

World Time Eco-Drive Radio Controlled Watch

This watch is a radio controlled watch, which receives the standard time radio waves that are broadcast from radio wave transmitters in three regions, Japan, the USA and Europe (Germany), and uses these waves to automatically correct the time and date. (p. 18)

i Automatic reception: The watch will automatically receive the radio wave up to three

times a day, at 2 a.m., 3 a.m. and 4 a.m., and adjust the time and date accordingly. However, note that if the watch successfully receives the radio wave at 2 a.m., it will not perform automatic reception again at the later times. The 4 a.m. automatic reception can be changed to any time of the day.

i On demand reception: The radio wave can be received at any time of the day to adjust

the time and date. In the event that a radio signal cannot be received, the watch can be manually set and will operate keeping time within +/- 15 seconds per month.

Important Points Regarding Radio Wave Reception

There are two methods to receive radio signals during normal operation, Automatic and On Demand. The internal unidirectional antenna may be weakened by geography or building structures, which may require the user to place the watch near a window. When receiving radio waves: * Remove the watch from your wrist * Face the 9:00 position of the watch towards a window * Place the watch on a stable surface * Do not move the watch during this process. Movement of the watch may cause

incomplete reception. During radio reception, the second hand of the watch moves in reception level.

* When reception is complete, the watch will return to movement at one-second

intervals. Reception can take from about 2 minutes to a maximum of 15 minutes.

i UTC (Coordinated Universal Time), the time and date of 43 cities (or regions) from around

the world and one city (any can be set) can be displayed and easily called up. It is convenient when traveling overseas on business or vacation. Daylight saving time can also be set. (p. 44)

This is a multi-functional Eco-Drive watch, which is equipped with a solar power function for powering the watch by converting light energy into electric energy.

i Charge level display function: This function displays the charge level in four grades, to

give an approximate indication of how much the secondary battery is charged. (p. 38)

i Power saving function: The watch is equipped with two power saving functions.

If the watch face is not exposed to light for 30 minutes or longer, all the LCD display sections turn off (Power saving 1). If the watch face is then not exposed to light for one week or longer, the hands are stopped in order to minimize the watch’s power consumption (Power saving 2). (p. 92)

Automatic reception

• It is not necessary to operate buttons during automatic reception.

• The watch will automatically receive the radio wave every day at 2 a.m., 3 a.m. and 4 a.m.

• The 4 a.m. reception can be changed to any time of the day. (p. 66oo69)

• Reception can be set to OFF. (p. 66oo69)

1. Remove the watch from your wrist and place on

a stable surface in a location, such as near a window, from which radio waves can be easily received, pointing the 9:00 side (reception antenna position) in the direction of the radio wave transmitter.

2. The watch will automatically receive the radio

wave every day at 2 a.m. If it successfully receives the wave, reception is not performed at 3 a.m. and 4 a.m.

4. Radio Signal Reception

Three types of radio signal reception are possible: automatic reception, on demand reception and recovery automatic reception. There are three modes where reception is possible: time (TME), calendar (CAL) and receive set (RX-S). The watch cannot receive signals in any other mode. Display the home city in digital display 2 when receiving the radio wave.

• Reception is not possible unless the crown is in the normal position.

• If the home city is “UTC”, reception is not possible.

• Reception is not possible during chronograph or timer measurement.

• The reception level may change depending on the surrounding environment. While referring to reception level (H, M or L), change the watch location, direction and angle to try to receive the radio wave.

• When the watch is receiving the radio wave signal, all of the hands will stop. To check the time, hold the lower right button (A) for 2 seconds to cancel the radio wave reception. The hands will then return to the current time.

An antenna for receiving the radio signals is located inside the watch (on the 9:00 position).

20 21

Recovery Automatic Reception (Automatic Reception)

• If the watch stops due to insufficient charging, expose the watch to sunlight to recharge it. When the watch is recharged sufficiently, it will automatically receive the radio wave once.

* Regularly charge your radio controlled watch so it does not become insufficiently

charged. The radio wave reception can be checked with “Confirming Reception Status”. (p. 26)

On Demand Reception (Manual Reception)

• Signals can be received at any time.

1. Pull the crown out to position 1 and turn to align the mode hand with the CAL, TME or RX-S position.

2. Return the crown to the normal position.

3. Remove the watch from your wrist and place on a stable surface near a window where the radio signal can be easily received.

4. Point the 9:00 side of the watch in the direction of the radio wave transmitter, and hold down the lower right button (A) for more than 2 seconds. Release when the confirmation tone sounds and the second hand stops at RX. The second hand will then move to H, M or L. * Do not move the watch during reception.

5. When the radio wave has been properly received, the second hand will automatically move from H, M or L to the time that was received, all the hands will be corrected, and the second hand will return to 1-second interval movement.

5. Poor Reception Areas

It may not be possible to receive radio waves under environmental conditions where reception is difficult or in areas susceptible to radio noise, such as those shown in the illustrations below. While referring to the reception level display, try to find a location with better reception.

j Extremely hot or cold locationsj Near cellular

phones that are in use

j Inside vehicles, including

cars, trains and aero planes

j Near TVs, refrigerators,

computers, fax machines and other home electronics or appliances

j Inside reinforced concrete

buildings or underground

j Near high-tension electrical

lines, railway overhead wires or communication facilities

If the watch has received insufficient light for charging or has been kept in a dark location for an extended period of time (one week or more), the Power Save Feature of the watch is activated and the hands of the watch stop. Even though the watch will not show movement, the correct time is kept in memory. When the watch is in the Power Save mode, it will continue to keep the correct time internally. In some instances, “Automatic Reception” may not be successful due to a weak signal reception. When resuming use of the watch after the power save mode has been activated for an extended period of time, you can cancel the Power Save function by placing the watch in light sufficient for charging and performing the “On Demand” reception process to correctly set the time and date. (Refer to page 92 for information on the Power Save Function.)

24 25

Reception can take from about 2 minutes to a maximum of 15 minutes, depending on factors such as the weather or noise. If the radio wave reception fails, the watch may return immediately to the normal display.

[Caution] During reception, the second hand may

rotate once and show the reception level again. Do not move the watch until the second hand has returned to 1-second interval movement.
