...heart symbol flashes irregularly?
1. Check that the wrist receiver is not further than 3 feet/1 meter
from the transmitter.
2. Check that the elastic strap is snug (but it doesn’t need to
be overly tight).
3. Make sure that the electrodes of the transmitter are
moistened.
4. Make sure that there is no other heart rate transmitter within
3 feet/1 meter.
5. Cardiac arrhythmia may cause irregular readings. In this case
consult your physician.
...another student with heart rate monitor
is causing interference?
Your training partner may have exactly the same code as you. In
this case proceed as follows: Keep a distance from your training
partner and continue your training session as before.
Or
1. Take the transmitter off your chest for 30 seconds. Keep a
distance from your training partner.
2. Put the transmitter back and bring the receiver up to your
chest near the transmitter’s Polar logo. The receiver starts
looking for a heart rate signal again. Continue your training
session as before.
...heart rate reading becomes erratic or extremely high?
You may have come within range of strong electromagnetic
signals which cause erratic readings. Check your surroundings and
move further away from the source of disturbance. Interference is
much more likely if the HRM is receiving a non-coded heart rate
signal. In the Measure mode, look at the heart in the lower left
corner. A heart with the frame indicates coded transmission of
heart rate. A heart without a frame indicates a non-coded
transmission. If non-coded, move away from the disturbance and
take the transmitter off your chest for 30 seconds, and start your
exercising again.
