TIMEKEEPING MODE  
Pressing C in the Timekeeping Mode illuminates the display for about two sec-  
onds. The backlight is disabled while a setting screen is on the display.  
When using 12-hour timekeeping, a P appears on the display for “pm” times (noon  
to 11:59 pm). An “am” time (midnight to 11:59 am) is indicated when there is no P  
indicator on the display. 24-hour timekeeping is being used when the 24 indicator is  
on the display.  
About the Auto Light Switch Function  
When the auto light switch function is turned on, the backlight automatically turns on  
for two seconds under the conditions described below. Avoid wearing the watch on  
the inside of your wrist. Doing so causes the auto light switch to operate when not  
needed, which shortens battery life.  
Moving the watch to a position that is parallel to the ground and then tilting it  
towards you approximately 40 degrees causes the backlight to illuminate.

To set the time and date  
1. While in the Timekeeping Mode, hold down Auntil the  
seconds digits appear and flash on the display. This  
indicates the setting screen.  
Static electricity or magnetic force can interfere with proper operation of the auto  
light switch function. If the backlight does not illuminate, try moving the watch back  
to the starting position (parallel with the ground) and then tilt it back toward 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 the backlight may not light until about one second or less  
after turn the face of the watch towards you. This does not necessarily indicate  
malfunction of the backlight.

Caution  
The backlight of this watch employs an electro-luminescent (EL) light, which loses  
its illuminating power after very long term use.  
Frequent use of the backligfht shortens the battery life.  
The watch emits an audible sound whenever the display is illuminated. This is be-  
cause the EL light vibrates slightly when lit. It does not indicate malfunction of the  
watch.  
Daylight Saving Time (DST), which is also sometimes called “summer time” ad-  
vances the time for one hour, as is the custom in some areas during the summer.  
Remember that not all countries or even local areas use Daylight Saving Time.  
DST indicator 1 flashes while the DST setting is selected. It also appears in the  
Timekeeping Mode and Alarm Mode to indicate that DST is turned on. DST indica-  
tor 1 does not appear in the Timekeeping Mode when DST is turned off.  
DST indicator 2 appears (flashing) only while the DST setting is selected on the  
setting screen. 0 indicates that DST is turned off, while 1 indicates that DST is  
turned on.  
Warning!  
Never try to read your watch when mountain climbing or hiking in areas that  
are dark or in areas with poor footing. Doing so is dangerous and can result  
in serious personal injury.  
Never try to read your watch when running where there is the danger of acci-  
dents, especially in locations where there might be vehicular or pedestrian  
traffic. Doing so is dangerous and can result in serious personal injury.  
Never try to read your watch when riding on a bicycle or when operating a  
motorcycle or any other motor vehicle. Doing so is dangerous and can result  
in a traffic accident and serious personal injury.  
When you are wearing the watch, make sure that its auto light switch function  
is turned off before riding on a bicycle or operating a motorcycle or any other  
motor vehicle. Sudden and unintended operation of the auto light switch can  
create a distraction, which can result in a traffic accident and serious personal  
injury.

hour timekeeping.
