Troubleshooting

Hand Movement and Position■I lost track of what mode the watch is in.

Refer to ÒMode Reference GuideÓ (page E-20). To return directly to the Dual Time Mode, hold down C for at least two seconds.

■The x Second Hand is moving at two-second intervals.

■All the watch’s hands are stopped at 12 o’clock and none of the buttons work (x Second Hand stopped at 57, 58, 59, or 00).

Power may be low. Expose the watch to light until the x Second Hand starts moving normally, at one- second intervals (page E-10).

■The hands of the watch suddenly start moving at high speed, even when I do not perform any operation.

This could be due to any one of the following causes. In all cases, the hand movement does not indicate malfunction, and should stop shortly.

ξThe watch is recovering from a sleep state (page E-12).

ξThe time setting is being adjusted following a successful auto time calibration signal receive operation (page E-13).

■Hands suddenly stop moving. Button operation also is disabled.

The watch may be in the power recovery mode (page E-11). Do not perform any operation until the hands return to their normal positions (in about 15 minutes). The hands should return to their correct positions when normal operation returns. To help power recover, leave the watch in a location where it is exposed to light.

■The current time setting is off by hours.

ξYour Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page E-22).

E-40

■The current time setting is off by one hour.

ξIf you are using the watch in an area where time calibration signal reception is possible, see “To configure Home City settings” (page E-22).

ξThe period when summer time is applied in the location where you are using the watch may be different from the period set for your currently selected Home City. Use the procedure under “To switch between standard time and summer time manually” (page E-25) to switch from AUTO to STD (for standard time) or DST (for summer time).

■The hands and/or day indications are off.

This could indicate that the watch has been exposed to magnetism or strong impact, which has caused problems with proper hand and day alignment. Adjust the watchÕs hand and day home position alignment (page E-37).

■Data indication is correct, but it is not in the middle of the day indicator.

The . Day Indicator will change gradually between approximately 10 p.m. and 2 a.m. each day. If the date is misaligned during this period, it is only momentarily and does not indicate malfunction. If you change your Home City setting while the current time in the new Home City is between approximately 10 p.m. and 2 a.m., the date may become misaligned momentarily.

Charging■The watch does not resume operation after I expose it to light.

It can take quite a long time to charge the battery after the power level drops to Level 3 (page E-10). Continue exposing the watch to light until the x Second Hand starts moving normally (at one-second intervals).

■The x Second Hand starts to move at one-second intervals, but then suddenly returns to moving at two-second intervals.

The watch probably is not sufÞ ciently charged yet. Continue keeping it exposed to light.

Time Calibration Signal

The information in this section applies only when LONDON (LON), PARIS (PAR), ATHENS (ATH), HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC), HONG KONG (HKG), or TOKYO (TYO) is selected as the Home City. You need to adjust the current time manually when any other city is selected as the Home City.

■The x Second Hand indicates N (NO) when I check the result of the latest receive operation.

■The current time setting changes after I set it manually.

You may have the watch conÞ gured for Auto Receive of the time calibration signal (page E-16), which will cause the time to be adjusted automatically according to your currently selected Home City. If this results in the wrong time setting, check your Home City setting and correct it, if necessary (page E-22).
