2. Before Using A. Radio Wave Receiving Function 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.
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.
(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.

Solar-Powered Watch Handring Notes This watch uses a secondary battery (rechargeable battery) to store electrical energy.
When the watch becomes insufficiently charged due to not exposing the dial (solar cell) to light 7. Unique Functions of Solar-Powered Watches When the watch becomes insufficiently charged, the display changes as shown below.
A. Power Save Function When the solar cell is not exposed to light and power is not generated continuously for one week, each hand stops at the 12:00 position and the watch enters the Power Save mode (to reduce power consumption). · The date stops at a location between the previous day and the current day. After that, the date is automatically corrected at 12:00 AM once a day. · Regular automatic reception is still performed twice a day in the same manner as that during normal display.
B. Insufficient Charge Warning Function (Second hand moves at twosecond intervals) When the capacity of the secondary battery becomes low as a result of not exposing the solar cell to light, the second hand changes from one-second interval movement to twosecond interval movement (insufficient charge warning function) to indicate that the watch is insufficiently charged.
8. General Reference for Charging Times of Solar-Powered Watches The time required for recharging varies according to the model of the watch (color of the dial, etc.). The following times are shown below only to serve as a reference. · Recharging time refers to the amount of time the watch is continuously exposed to light.
9. Solar Powered Watch Handling Precautions CAUTION : Handling of Secondary Battery CAUTION : Charging Precautions • Never attempt to remove the secondary battery from the watch. If the secondary battery must unavoidably be removed, store it out of the reach of small children to prevent accidental swallowing. • If the secondary battery should happen to be swallowed, consult a physician immediately and seek medical attention.
10. Setting the Reference Position Check the reference position if the watch does not indicate the correct time even after having received radio waves. In the case the reference position (0 position/12:00 position), which serves as the reference for all watch functions, has shifted, check the reference position of each hand using the procedure described below.
· Turning the crown continuously (by two clicks or more) causes the hour hand to move continuously. When the hour hand makes two revolutions, the date changes by one day. Continuously advance the hour hand until the date is displayed between 31 and 1. Turn the crown to the left or right to interrupt continuous movement of the hour hand. · After the date displays between 31 and 1, slowly turn the crown until the hour hand indicates 12:00.
B. Setting the Reference Position after All-Reset 11. All-Reset The watch display may become abnormal due to the effects of static electricity or a strong shock. If this happens, perform the all-reset procedure and then set the reference position. A. All-Reset Procedure (1) Pull out the crown to the second position. · The second hand rapidly moves to the reference position stored in memory and stops. (2) Press buttons (A) and (B) simultaneously.
Note: If the crown is accidentally pushed in too far to the normal position when the crown is pushed in from the second position to the first position, since this will end setting of the reference position causing the hands to move normally, it will not be possible to set the reference position for the hour hand and date. If the crown has returned to the normal position, set the reference position by referring to “10. B. Setting the Reference Position”. Alternatively, repeat the all-reset procedure again.
12. Troubleshooting Radio Wave Reception Function: Try checking the following when you think a problem has occurred. Problem Check Items Corrective Actions Watch does not begin reception · Does the shorter end of the second hand move to “RX: Reception standby”? Continuously depress button (A) and release when the shorter end of the second hand points to the RX position.
