Before use
Backlight
Pressing and holding the MODE1 or MODE2 button illuminates
the display for about 3 seconds (Except in the Setup mode).
Pressing any button while backlight is still on extends the illu-*
mination for another 3 seconds.
Power-saving mode
Transmission sleep mode
When the wristwatch does not receive any data from the speed
sensor or heart rate sensor for 5 minutes, each sensor will
enter the transmission sleep status to save battery power. No
sensor signal can be received in the transmission sleep status.
To restart measuring, press the MODE1 or MODE2 button to
recover from transmission sleep. The signal transmission
status of each sensor can be checked with the relevant signal
icon and the numerical value “---” display.

Transmission sleep. Displays the symbol “---”.
Transmission sleep is set separately for the speed sensor *
and the heart rate sensor. Accordingly, if the bicycle is
stopped for over 5 minutes with the heart rate sensor worn,
only the speed sensor goes into transmission sleep. When
resuming the ride, speed/cadence sensor must be re-acti-
vated in order to display necessary data.
When either the speed sensor or the heart rate sensor is in *
transmission sleep, the display remains in the Sports mode;
however, when both sensors go into transmission sleep,
the wristwatch switches to the power-saving mode.
Saving the power of the wristwatch
When the wristwatch does not receive any data from both the
speed and heart rate sensors for 5 minutes, it will switch to
Clock mode automatically. Press the MENU button to return
to Sports mode and continue measuring. For details, see
“Switching between modes” on page 21.
Even if the power-saving mode is activated, data not reset *
are saved in the wristwatch.
