Operation Guide 3107

12-hour/24-hour Timekeeping Formats

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also applied in all other modes.

•With the 12-hour format, the PM indicator (P) appears on the display for times in the range of noon to 11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m.

•With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.

Illumination Precautions

•The electro-luminescent panel that provides illumination loses power after very long use.

•Illumination may be hard to see when viewed under direct sunlight.

•The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.

•Illumination turns off automatically whenever an alarm sounds.

•Frequent use of illumination runs down the battery.

•Based on data as of June 2008.

•The rules governing global times (UTC offset and GMT differential) and summer

time are determined by each individual country.

*In December 2007, Venezuela changed its offset from –4 to –4.5. Note, however, that this watch displays an offset of –4 (the old offset) for the CCS (Caracas, Venezuela) city code.
