BACKLIGHT FUNCTION
A backlight that uses an EL (electro-luminescent) panel
causes the entire display to glow for easy reading in the
dark. An EL alarm feature can be turned on so the backlight
flashes whenever an alarm or hourly time signal sounds.
• The FLASH indicator is shown on the display in all modes
while the EL alarm is on.
Note
• The backlight of the watch employs an electro-liminescent
(EL) light, which loses illuminating power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch will emit an audible sound whenever the display is illuminated. This is caused
by a transformer that vibrates when the EL panel lights up. It does not indicate
malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.
To manually turn on the backlight
Pressing L in the Timekeeping, Stopwatch or Alarm Mode causes the backlight to turn
on for about two seconds. Pressing C in the Beat Counter Mode also causes the backlight
to turn on for a fixed amount of time.
• The backlight normally stays on for about two seconds and then turns off automatically.
When the EL alarm is turned on, however, the backlight stays on for about five seconds
instead of two seconds.
• The above operations turn on the backlight, regardless of the current EL alarm settings.

In the Timekeeping Mode, hold down B for about two seconds to toggle the EL alarm
on (FLASH indicator displayed) and off (FLASH indicator not displayed).
• When the EL alarm is on, the backlight flashes while the daily alarm and hourly time
signal tones are sounding. Also, the backlight stays on for about five seconds instead
of the normal two seconds.
BEAT COUNTER MODE
The Beat Counter Mode can be used to produce an audible
signal in accordance with BPM (beats per minute) value,
which is like a digital metronome that can be used for a
variety of different musical applications.
• The letters “BPM” stand for “beats per minute” in this
manual.
• Any time you enter the Beat Counter Mode, the last BPM
value you set appears on the display.
• If you do not operate any button for one hour while in the
Beat Counter Mode, the watch automatically goes back
to the Timekeeping Mode.
To play the beat signal
In the Beat Counter Mode, press B to start a digital beat signal that sounds at the
speed indicated by the BPM value. The higher the BPM value, the faster the beat.
• The digital beat signal sounds for one minute or until you press any button to stop it.

BPM value
Setting the BPM value
There are two ways you can set the BPM value: by counting beats of some music or
rhythm, or by manually inputting a value.
To count beats
1.In the Beat Counter Mode, press L six times in
accordance with the beat of the music or rhythm.
• Each time you press L, the number on the display
changes in the following sequence:
1 → 2 → 3 → 4 → 0
2. After you press L the sixth time, the watch calculates an
average number of beats per minute and sets the
applicable BPM value.
• Note that you must press L all six times for this procedure to work correctly.
• If you do not press L within about three seconds after you last pressed it, the watch
automatically cancels the beat count procedure.
• The above procedure sets a value in the range of 60 to 200 beats, in 5-beat steps.
To manually input a value
1. In the Beat Counter Mode, hold down A until the BPM values starts to flash.
2. Press C to increase the BPM value in units of 5 or B to decrease it. Holding down
either button changes the setting at high speed.
• You can set the BPM value within a range of 60 to 200.
• Pressing B and C at the same time changes the BPM value to its standard setting of
120.
3. After you input the BPM value, press A to return to the normal Beat Counter Mode
screen.
