Adjusting Home Positions Manually
Strong magnetism or impact can cause the hands of the watch to be off, even if the watch is able to perform the signal receive operation. When this happens, you can manually adjust the hand home positions to ensure correct timekeeping.
•Hand home position adjustment is not necessary as long as the hands are indicating time correctly.
To adjust home positions manually
1. Enter the Hand Home Position Adjustment Mode (page
• The digital display will show HS, followed by the current Timekeeping Mode time. You can use the digital display to check if the hand positions are correct and to confirm whether the analog time indication matches the digital time.
2. Hold down E until each of the following steps occurs.
• Hold SET appears on the digital display. ➝ SEC 00 flashes.
• The second hand should move to 12 o’clock at this time. If it doesn’t, use A (+) to move the second hand so it aligns with 12 o’clock.
3. After the second hand is aligned correctly, press D.
• The hour and minute hands should move to 12 o’clock. If they don’t, use A (+) and C
• Pressing D here returns to the second hand home position adjustment in step 2.
4.After adjusting the hour hand and minute hand home positions, press E.
•After adjusting the home positions of the hands, leave the watch in a location where time calibration signal reception is good and perform manual receive. Next, check to make sure that the hands are indicating the time correctly. See “To perform manual receive” (page

• You can use the procedure below to select either one second or three seconds as the illumination duration. When you press L, illumination will remain on for about one second or three seconds, depending on the current illumination duration setting.
•The above operation turns on illumination regardless of the current auto light switch setting.
•Illumination cannot be used during time calibration signal reception, in a sensor mode, while a compass operation is in progress, or while hand home position adjustment is being performed.
To change the illumination duration
1. In the Timekeeping Mode, hold down E until each of the following steps occurs.
• Hold SET appears on the digital display. ➝ HT flashes. ➝ Second hand points to the current Home City code.
2. Use D to cycle through the settings on the digital display until the current illumination duration (LT1 or LT3) is shown.
• See step 3 under “To change the current time and date settings manually” (page
3.Press A to toggle the illumination duration between three seconds (LT3 displayed) and one second (LT1 displayed).
4.After all the settings are the way you want, press E to exit the setting screen.

Warning!
•Always make sure you are in a safe place whenever you are reading the display 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.
•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, unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.
Note
•This watch features a “Full Auto LED Light”, so the auto light switch operates only when available light is below a certain level. Illumination does not turn on under bright light.
•The auto light switch is always disabled, regardless of its on/off setting, when any one of the following
conditions exists.
While an alarm is sounding During sensor measurement
While a bearing sensor calibration operation is being performed in the Compass Mode While a receive operation is in progress in the Receive Mode
While a hand home position adjustment operation is in progress
To turn the auto light switch on and off
1. In the Timekeeping Mode, hold down E until each of the following steps occurs.
• Hold SET appears on the digital display. ➝ HT flashes. ➝ Second hand points to the current Home City code.
2. Use D to cycle through the settings on the digital display until the current auto light switch setting (AT OFF or AT On) is flashing on the digital display.
•See step 3 under “To change the current time and date settings manually” (page
3.Press A to toggle the auto light switch setting between on (On) or off (OFF).
4.After the setting is the way you want, press E to exit the setting screen.
Illumination Precautions
•Frequent use of illumination can run down the battery, which will require exposing the watch to light for charging.
The following guidelines give an idea of the charging time required to recover from a single illumination operation.
Approximately five minutes exposure to bright sunlight coming in through a window Approximately 50 minutes exposure to indoor fluorescent lighting
•Illumination may be hard to see when viewed under direct sunlight.
•Illumination turns off automatically whenever an alarm sounds.
•Frequent use of illumination runs down the battery.
Auto light switch precautions
•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. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination.
•Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination and can run down the battery.
•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.
• Illumination turns off after the preset illumination duration (page
• 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.
•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.
