Time Recorder
The Time Recorder lets you store up to 30 records of the
current time (month, day, hour, minutes, seconds, and
DST on/off setting) with the touch of a button. One way
you can use the Time Recorder is to record the start time
and the end time of a particular event.
To record a Time Recorder time
In the Timekeeping Mode, hold down B to record the
Home City time (month, day, hour, minutes, seconds, and
DST on/off setting).
• The recorded time flashes for about two seconds, and
then it is assigned a record number. After that, the
Timekeeping Mode screen appears.
• Records are assigned numbers sequentially from
#01
through #30.
• Storing a new time record when there are already 30
records stored in memory automatically deletes record
#01, shifts the remaining records upwards by 1, and
stores the new record as
#30.

Backlight
The backlight uses an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch automatically turns on
the backlight when you angle the watch towards your face
in the dark.
• The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
• See “Backlight Precautions” for other important
information about using the backlight.
To turn on the backlight manually
In any mode, press L to illuminate the display for about
one second.
• The above operation turns on the backlight regardless of
the current auto light switch setting.

About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one second,
whenever you position your wrist as described below in any mode. Note that this
watch features a “Full Auto EL Light,” so the auto light switch operates only when
available light is below a certain level. It does not turn on the backlight under bright
light.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to turn on.

Warning!
• Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
surprise or distract others around you.
• When you are wearing the watch, make sure that its auto light switch 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.
