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.

Approximate Battery Operating Time
9 months (from full charge to Level 4 when the watch is not exposed to light)
under the following conditions:
• Display on 18 hours per day, sleep state 6 hours per day
• 1 illumination operation (1.5 seconds) per day
• 10 seconds of alarm operation per day
• 10 minutes of signal reception per day
Frequent use of illumination can shorten battery operating time.

• 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.
