2.1 MEASURING YOUR HEART RATE Exercise Time Indicator
1 bullet = 10 minutes of exercise, 6 bullets = 1 hour of exercise.
After one hour, when all the bullets are filled in, the cycle
starts again.
After 9 hour 59 minutes of exercise the wrist unit returns to
the OFF mode/
TIME mode (F3) . To start measuring your
heart rate again, press the side button. This deletes the
previous file.
3. To check your exercise time while exercising bring the
wrist unit up to the Polar logo on the transmitter.
Your elapsed exercise time appears for six seconds.
Before the stopwatch starts, the target heart rate limits,
that will be used while you exercise, are shown once on the
display. The target heart rate alarm symbol
is shown
provided that you have switched it on.
If the wrist unit does not detect your heart rate signal, 00
appears on the display as your heart rate value. If there is
no heart rate signal for more than five minutes, the receiver
automatically returns to the OFF mode/
TIME mode .
1. Press the side button to start.
Keep a minimum of 3 feet/1 meter
away from other heart rate monitor
users until the heart rate symbol
appears and flashes evenly.
2. The stopwatch starts. Your heart rate appears in six
seconds. The heart rate symbol flashes in time with
the beat of your heart.
