REFERENCE
This section contains more detailed and technical information about watch operation. It
also contains important precautions and notes about the various features and functions
of this watch.
Auto Return Operations
If you leave the watch in BPM or Beat Mode for about one hour without performing any
operation, it automatically changes to the Timekeeping Mode.
If you leave a screen with flashing digits on the display for two or three minutes without
performing any operation, the watch automatically saves anything you have set up to
that point and exits the setting screen.
Scrolling
The B and D buttons are used in various modes and screens to scroll through available
settings on the display. In most cases, holding down these buttons scrolls at high speed.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in the Alarm Mode.
Backlight Precautions
The backlight use an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode (except when making settings), press B
to illuminate the display.
The backlight remains lit for about eight seconds in the BPM and Beat Modes, and for
about two seconds in other modes.
The electro-luminescent panel 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.
Frequent use of the backlight shortens the battery life.
BPM Mode Notes
The watch cannot calculate a BPM value in either of the two following cases.
When you press
E
fewer than five times.
When you allow more than two seconds to pass between presses of
E
.
The watch will calculate a BPM value even if you press E more than five times. In this
case, it uses the average timing of the last five presses of the E button.
The BPM value is set within a range of 60 to 200 beats per minute. A beat below 60 is
indicated by
Lo on the display, while a beat above 200 is indicated by H .
You can enter the BPM Mode from the Timekeeping Mode by pressing E.
Countdown Start Time
The Countdown Alarm Mode has five built-in start times (60, 74, 90, 120, 180) that
match the lengths of today’s cassette tapes and mini disks (MD). You also get one
user memory area in which you can store a starting time of your own.
You can set a user start time in the range of 1 to 180 minutes, in 1-minute steps. When
you do, it is automatically inserted into its proper location among the built-in start times.
If you set a user start time of 86, for example, it will be inserted between 74 and 90.
This means when you scroll through the available start times on the watch display to
select one, they will cycle in the sequence: 60 74 86 90 120 180.
You can have only one user start time. If you set a new user start time while there is
already one in memory, the new time replaces the old one, which is deleted.
