Operation Guide 3725 3726
Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany. You can select either one of the transmitters, or you can configure the watch to automatically select the transmitter that has the strongest signal.
•The following explains how the watch determines which transmitter it should check first while the watch is configured for auto transmitter search (AvtA).
Module 3725
In this case: | The watch does this: |
The first signal auto search operation | 1. Checks the Mainflingen signal first. |
after factory default settings are in effect, | 2. If the Mainflingen signal cannot be |
or after the city code has been changed | received, checks the Rugby signal. |
Any case other than the above. | 1. Checks the last successfully received |
| signal first. |
| 2. If the last successfully received signal |
| cannot be received, checks the other |
| signal. |

Module 3726 |
|
In this case: | The watch does this: |
The first signal auto search operation | 1. Checks the Rugby signal first. |
after factory default settings are in effect, | 2. If the Rugby signal cannot be received, |
or after the city code has been changed | checks the Mainflingen signal. |
Any case other than the above. | 1. Checks the last successfully received |
| signal first. |
| 2. If the last successfully received signal |
| cannot be received, checks the other |
| signal. |
•Since the watch checks signals from both transmitters when AvtA is selected as the transmitter setting, signal reception can take as long as 14 minutes.

Timekeeping
•Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.
•The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.
•The year can be set in the range of 2000 to 2099.
•The watch’s
•The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting.
•GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.

Illumination Precautions
•Illumination may be hard to see when viewed under direct sunlight.
•Illumination automatically turns off whenever an alarm sounds.
•Frequent use of illumination runs down the batteries.
Auto light switch precautions
•The auto light switch is turned off automatically whenever battery power is at Level 3.
•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 digital display areas. To avoid running down the batteries, 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 of the digital display areas and can run down the batteries.
More than 15 degrees | • Illumination may not turn on if the face of the watch is |
too high | 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 (see “To set the current digital time and date |
| manually”), even if you keep the watch pointed towards |
| your face. |
•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 you 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.
•Under certain conditions, illumination may not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch.
•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.
