E-51  
Warning!  
4. After all of the settings are the way you want, press A to exit the setting mode.  
x Exiting a setting mode will normally cause the hands to return to regular  
timekeeping automatically. However, if you manually move the hands (page  
E-61) and then enter a setting mode, they will not return to regular timekeeping  
automatically when you exit the setting mode. In this case, you will need to  
return the hands to their normal positions manually (page E-62).  
x Always make sure you are in a safe place whenever you are reading the  
face of the watch using the auto light switch. Be especially careful when  
running or engaged in any other activity that can result in accident or  
injury. Also take care that sudden illumination by the auto light switch does  
not startle or distract others around you.  
x When you are wearing the watch, make sure that its auto light switch is  
turned off before riding on a bicycle or operating a motorcycle or any other  
motor vehicle. Sudden and unintended operation of the auto light switch  
can create a distraction, which can result in a traffic accident and serious  
personal injury.  
About the Auto Light Switch  
Turning on the auto light switch causes illumination  
to turn on, whenever you position your wrist as  
More than  
described below in any mode.  
40°  
Moving the watch to a position that is parallel to  
the ground and then tilting it towards you more  
than 40 degrees causes illumination to turn on.  
Note  
Wear the watch on the  
outside of your wrist  
x This watch features a “LED”, so the auto light switch operates only when available  
light is below a certain level. It does not illuminate the face under bright light.  
E-52  
E-53  
Auto light switch precautions  
To turn the auto light switch on and off  
x Wearing the watch on the inside of your wrist, movement of your arm, or vibration  
of your arm can cause frequent activation of the auto light switch and illumination  
of the face. To avoid running down the battery, turn off the auto light switch  
whenever engaging in activities that might cause frequent illumination of the face.  
x Note that wearing the watch under your sleeve while the auto light switch is turned  
on can cause frequent illumination of the face and can run down the battery.  
In the Timekeeping Mode, hold down B for about  
three seconds to toggle the auto light switch on  
(indicator displayed in the right digital dial) and off  
(indicator not displayed).  
x The auto light switch on indicator appears in all  
modes while the auto light switch is turned on.  
x The auto light switch turns off automatically whenever  
battery power drops to Level 4 (page E-15).  
x Illumination may not turn on if the face of the watch is more than  
15 degrees above or below parallel. Make sure that the back of  
your hand is parallel to the ground.  
Auto light switch on indicator  
x Illumination turns off after the preset illumination duration (page  
E-51), even if you keep the watch pointed towards your face.  
x Static electricity or magnetic force can interfere with proper  
operation of the auto light switch. If illumination does not turn on,  
try moving the watch back to the starting position (parallel with the  
ground) and then tilt it back towards your face again. If this does  
not work, drop your arm all the way down so it hangs at your side,  
and then bring it back up again.  
Illumination Precautions  
x LED panel that provides illumination loses power after very long use.  
x Illumination may be hard to see when viewed under direct sunlight.  
x Illumination turns off automatically whenever an alarm sounds.  
x Frequent use of illumination runs down the battery.  
E-54  
E-55  
x You may notice a very faint clicking sound coming from the watch when it is  
shaken back and forth. This sound is caused by mechanical operation of the auto  
light switch, and does not indicate a problem with the watch.  
Hand Home Position Adjustment  
Strong magnetism or impact can cause the hands of the watch to be off.  
x Home position adjustment is not necessary when the analog time and digital time  
are the same time in the Timekeeping Mode.  
To adjust home positions manually  
1. In the Timekeeping Mode, hold down A and keep it depressed for about five  
seconds until H.SET appears in the right digital dial.  
x The hour and minute hands should all move to 12 o’clock, which is their home  
position.  
x Though ADJ will appear in the right digital dial about two seconds after you hold  
down A, do not release the button yet. Keep it depressed until H.SET appears.  
When H.SET appears in the right digital dial, release the A button. This will

any operation for about two or three minutes. Any changes you have made to  
settings up to that point will be saved.  
After performing home position adjustment, enter the Timekeeping Mode and check  
to make sure that the analog hands and the digital dial indicate the same time. If  
they do not, perform home position adjustment again.  
If the hour and minute hands are all at 12 o’clock, which is their home position,  
jump to step 3.  
2. Use D (+) and B (–) to adjust the hour and minute hand positions.  
x Holding down either button will cause the hand to move at high speed. Once  
started, high-speed hand movement will continue even if you release the button.  
To stop high-speed hand movement, press any button.  
x High-speed hand movement started with the D (+) button will stop  
automatically after 12 revolutions of the minute hand. If started with the B (–)  
button, it will stop after one revolution of the minute hand.

Troubleshooting  
Time Setting  
The current time setting is off by hours.  
Your Home City setting may be wrong (page E-26). Check your Home City setting  
and correct it, if necessary.  
The current time setting is off by one hour.  
You may need to change your Home City’s standard time/daylight saving time  
(DST) setting. Use the procedure under “To change the current time and date  
settings” (page E-31) to change the standard time/daylight saving time (DST)  
setting.  
The hands are off.  
This could indicate that the watch has been exposed to magnetism or strong  
impact, which has caused problems with proper hand alignment. Adjust the watch’s  
hand home position alignment (page E-57).

The analog hands are not indicating the correct time.
