ACQUIRING HEART RATE WHILE WEARING THE CHEST BELT
The Sportline 560 Duo Heart Rate Monitor is equipped with a 10-hour, 25-lap
Chronograph (stopwatch) which also doubles as an exercise timer. When this timer
is activated, the watch will automatically begin displaying the heart rate reading
from the chest strap. To operate the chronograph and begin acquiring heart rate:
1. Press the Start/Stop (S/S) key while in Heart Rate/Chronograph mode,
and the chronograph will begin timing and trying to acquire the heart rate.
NOTE: The watch will automatically begin trying to acquire the heart rate (a flashing heart
icon will be shown on the screen) from the chest strap once the start/stop key is pressed
and the timer begins running.
2.
To time a lap, PRESS the S/S key. Split time will display for period of
10 seconds and timing will resume (to review Chronograph data,
see Page 20 “Chronograph Memory”).
3. To STOP timing, PRESS & HOLD the S/S key for 2 seconds.
4. To RESET the Chronograph, PRESS & HOLD the RESET (R) key.
NOTE: To view heart rate data in Memory, DO NOT RESET THE CHRONOGRAPH.
NOTE: The chest strap must be worn at all times to display a continuous heart rate reading on
the watch. See p.8 for details on wearing the chest strap.
NOTE: If issues acquiring heart rate, ensure that the chest strap is fitted firmly to the chest and
that the conductive pads touching the skin have been moistened with sweat or water. Dry skin
can prevent accurate readings.
