WThis watch is a radio wave watch that W receives the standard time radio wave transmitted in Germany.

This radio wave watch is equipped with a regular automatic reception function that sets the time and date by automatically receiving radio waves twice a day at 3:00 AM and 4:00 AM, and a free reception function that allows the time to be set arbitrarily by receiving radio waves. A time difference can also be set in 1 hour units based on German standard time.

·This watch only receives the standard time radio wave transmitted in Germany during radio wave reception. It is unable to receive radio waves of countries other than Germany.

·When using the watch in a location that has a different time difference than that of Germany, set the time difference by referring to the section entitled, “5. Time Difference Correction Function”. If the standard time radio wave transmitted in Germany is received after setting the time difference by another method, the time will return to German standard time.

WPlease use this watch afterW charging sufficiently by placing in light.

If the second hand of the watch is moving at two-second intervals while the watch is in use, this indicates that the watch is insufficiently charged. Use the watch after first recharging by placing the watch under direct sunlight for about 8 hours. To ensure that this Eco-Drive Radio Wave Watch is used comfortably without stopping, it is recommended to try to keep the watch fully charged at all times.

WImportant Points Regarding Radio Wave

ReceptionW

The two ways to receive radio waves that are ordinarily used consist of Regular Automatic Reception and Free Reception. When receiving radio waves, first remove the watch from your wrist, face the 9:00 position on the watch towards the radio wave transmitter station, and place the watch in a stable location that facilitates reception of radio waves such as in front of a window. Since the watch uses a directional antenna, moving the watch while reception is in progress may prevent radio waves from being properly received. When reception

is completed, the second hand returns to one-second interval movement. Do not move the watch until radio wave reception is completed.

[Regular Automatic Reception]

The watch sets the time and date by automatically receiving radio waves at the predetermined times of 3:00 AM and 4:00 AM each day.

Check the reception result to determine whether or not radio waves have been received properly by pressing button (A) located at the 4:00 position once. If the shorter end of the second hand points to H, M or L, this indicates that radio waves have been received properly. The watch can now be used.

If the shorter end of the second hand points to NO at the 5:00 position, this means that radio waves were unable to be received properly. If this happens, perform radio wave reception using the Free Reception function.

[Free Reception]

The Free Reception function lets you receive radio waves at any time. Use this function when the reception environment has changed or in other cases when radio waves are unable to be received by Regular Automatic Reception.

(1)Press button (A) located at the 4:00 position for about 2 seconds, and then release the button after the shorter end of the second hand has moved to the RX (6:00) position.

(2)The shorter end of the second hand then moves to H, M or L indicating that reception is in progress.

(3)When reception is completed, the shorter end of the second hand moves from H, M or L and returns to one-second interval movement.

*Refer to “3. Receiving Radio Waves” for further details on the procedure for receiving radio waves.

WWhen Storing in a Dark Location for a Long Period of TimeW

If the watch is stored in a location out of the light for a period of one week or more, the Power Save Function of the watch is activated and the watch stops. Even though the watch is in the Power Save mode, it still continues to perform Regular Automatic Reception and the watch continues to keep the correct time internally. However, the time may not be able to be corrected as a result of being unable to receive radio waves depending on the manner in which the watch is stored. When resuming use of the watch after storing for an extended period of time, cancel the Power Save function by placing the watch in the light and then perform Free Reception to correctly set the time and date.

* Refer to “7. A. Power Save Function” for information on the Power Save function.

1. Features

This watch is a radio wave watch that automatically corrects the time and date by receiving a standard time radio wave (time information) transmitted in Germany. It is also equipped with a time difference setting function that allows time differences to be set in one hour units based on German standard time when the watch is used in regions where the time difference differs from that of Germany. In addition, this watch is also an Eco-Drive radio wave watch provided with a photoelectric power generation function that converts light energy into electrical energy to drive the watch. It is also equipped with a power save function that reduces power consumption of the watch when the solar cell is not exposed to light.

2. Before Using

A. Radio Wave Receiving Function

<For Good Reception>

This watch incorporates an antenna for receiving radio waves inside the watch case (at the 9:00 position). For good reception, it is ideal to have the 9:00 position of the watch facing in the direction of the radio wave transmitter station when receiving radio waves. The reception level varies depending on the environment in which the watch is used.

Try receiving radio waves while changing the orientation or location of the watch while referring to H, M or L that indicates the reception level of the watch. Find the location and direction where radio waves are received easily as indicated by H or M being indicated for the reception level.

•For stable reception, remove the watch from your wrist and place the watch in a stable location that facilitates reception of radio waves such as in front of a window. Do not move the watch during reception.

•Radio waves may be hard to receive due to blockage by metallic objects or the environment. When inside a building and so on, reception should be performed as close to a window as possible.

<Locations where Reception may be Difficult>

It may not be possible to properly receive radio waves at the following locations susceptible to generation of radio wave noise or under the following environmental conditions that cause difficulty in receiving radio waves.

(1)Locations subject to extremely high or low temperatures

(2)Inside a reinforced concrete building, between tall buildings or in valleys between mountains or underground

(3)In a car, train or airplane

(4)Near high-tension wires (power lines), railroad overhead wires or airports (communication facilities)

(5)Near a cellular telephone in use

(6)Near household electric appliances or OA equipment such as TV sets, refrigerators, personal computers, fax machines, etc.

3. Receiving Radio Waves

In addition to the most commonly used Regular Automatic Reception and Free Reception, radio waves can also be received by using Recovery Automatic Reception by which radio waves are received when the watch is charged until the second hand moves at one-second intervals after having stopped due to being insufficiently charged. The time and date are corrected automatically when radio waves have been properly received. When reception is completed, each hand either moves forward or backward to indicate the received time.

[Data Received from German Standard Time Radio Waves]

·Time information: Hours, minutes, seconds, daylight savings time

·Date information: Month, day, year

A. Reception Modes

1. Regular Automatic Reception

The shorter end of the second hand moves to the RX: Reception Standby position and the watch automatically begins to receive radio waves twice a day at 3:00 AM and 4:00 AM.

·Remove the watch from your wrist and place it in a stable location where radio waves can be received easily such as by a window with the 9:00 position of the watch facing in

the direction of the radio wave transmitter station. The watch automatically receives radio waves twice a day at 3:00 AM and 4:00 AM.

2. Free Reception

Reception begins when button (A) at the 4:00 position is pressed for about 2 seconds. Remove the watch from your wrist and place it in a stable location where radio waves can be received easily such as by a window with the 9:00 position of the watch facing in the direction of the radio wave transmitter station. When reception is completed, the second hand returns to one-second interval movement. Do not move the watch until reception is completed.

(1)Press button (A) located at the 4:00 position for about 2 seconds and then release.

·Confirm that the shorter end of the second hand has moved to the RX: Reception Standby position (6:00 position).

(2)Place the watch in a stable location where radio waves can be received easily such as by a window with the 9:00 position of the watch facing in the direction of the radio wave transmitter station.

(3)After that, the shorter end of the second hand moves from the RX position to H, M or L indicating that reception is in progress.

(4)When reception is completed, the shorter end of the second hand moves from H, M or L and returns to one-second interval movement.

·Do not move the watch until the second hand returns to one-second interval movement.

3. Recovery Automatic Reception

When the watch has stopped as a result of being insufficiently charged, recharge the watch by sufficiently exposing it to light until the second hand moves at one second intervals. Radio waves are then received once automatically when the watch is sufficiently charged.

·Place the watch in a stable location where it is exposed to direct sunlight and where radio waves can be received easily such as by a window with the 9:00 position of the watch facing in the direction of the radio wave transmitter station. Reception of radio waves begins automatically once the watch has been sufficiently charged.

Note: Before using the watch, check the reception result. If radio waves have not been received properly, perform Free Reception to properly receive radio waves.

B. Position of the Shorter End of the Second Hand during Reception (Shorter End of Second Hand)

[Reception Standby]

[Reception in Progress]

[Completion of Reception]

·The shorter end of the second hand moves to the RX position and begins preparation for receiving radio waves.

·The minute hand stops at the position corresponding to the second hand.

·The shorter end of the second hand moves the position corresponding to the reception level and reception begins.

·During the time radio waves are being received (while the shorter end of the second hand is indicating the reception level), the second hand and minute hand may move to correct the time.

·When reception is completed, each of the hands and the date are corrected automatically and the second hand resumes one-second interval movement.

It takes from about 2 to 13 minutes to receive radio waves. If reception has failed, it may take as much as about 50 seconds for the watch to return to the normal display.

Note: The shorter end of the second hand moves from the RX (Reception Standby) position to the Reception Level (H, M or L) position while reception is in progress. When reception is completed, the second hand returns to one-second interval movement. Do not move the watch until the second hand returns to onesecond interval movement.

C. Confirmation of Reception Result

·When button (A) is pressed once following completion of reception, the shorter end of the second hand rapidly moves to H, M, L or NO enabling you to confirm the reception result.

Note: Free reception begins if button (A) is pressed continuously for 2 seconds or more.

·The reception result is indicated for 10 seconds after which the watch automatically returns to the current time. In addition, the watch can also be returned to the current time by pressing button (A) while the reception result is indicated.

·When reception was successful: The time and date are corrected automatically based on the reception result, and the shorter end of the second hand begins one-second interval movement.

·When reception has failed: The watch returns to the time resulting from adding the amount of time required for reception to the time and date display prior to reception, and the second hand begins one-second interval movement.

D. Reception Level and Reception Result

·During the standard time radio waves are being received, the shorter end of the second hand waits at the reception level position corresponding to the reception state to indicate the reception level. Following reception, the reception result can be confirmed by pressing button (A) once.

E. General Reference for Receiving Areas

The following provides a general reference for those areas where the watch is able to receive standard time radio waves. However, these areas may vary depending on the time, seasonal variations and weather (presence of lighting, etc.). Since this map only provides a general reference of the standard receiving areas, it may not apply in some particular locations even within the range shown on the map.

Standard time radio wave	Location of transmitter	General reference for areas where radio

4. Manually Setting the Time and Date

This watch allows the time and date to be set manually when radio waves are unable to be received.

<Screw-Lock Type Crown>

·If the crown of your watch is of the screw-look type, operate the crown after first loosening the screw locking mechanism by turning the crown to the left. When finished operating the crown, turn the crown to the right while pushing in after having returned it to the normal position and tighten securely.

·After having manually corrected the time and date or after having corrected the time difference, make sure to securely tighten the screw locking mechanism of the crown after returning it to the normal position. Since the watch will continue to be in the hour hand and date correction mode or time difference correction mode, etc. if the screw locking crown is tightened immediately after completion of hand movement, the hour hand will advance causing the set time and so forth to be incorrect.
