Illumination Precautions
An LED (light-emitting diode) and a light guide panel illuminate the face of the watch
for easy reading in the dark. In any mode, press B to illuminate the face of the watch
for about one second.
• The illumination provided by the light may be difficult to see when viewed under
direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination shortens the battery operating time.

• Based on data as of December 2008.
• UTC offsets and the use of summer time are subject to change in the country where
they are used.
* In December 2007, the UTC offset for Caracas, Venezuela (CCS) was changed from
– 4.0 to – 4.5. However, this watch still uses the old UTC offset of – 4.0 when the
