c. Be sure you have made a
long press
(i.e., press and hold)
of the Mode button from the appropriate screen.
d. Check the battery in your transmitter.
What if the heart rate reading becomes extremely high
(above 200)?
When exercising with your Axiom HR200 heart rate monitor
you may come within range of electromagnetic signals,
causing the heart rate reading to elevate to abnormal levels.
Common sources of electromagnetic signals are high voltage
power lines and motor driven equipment. Signals from other
users transmitter belts (within 80 cm) can also cause incor-
rect readings. Check your surroundings and move away from
the source.

Replacing Batteries
Transmitter
Unscrew the battery compartment counterclockwise, using a
coin (see Fig. 10). Before you remove the old battery, note
its orientation. Please be sure that the new battery is
inserted with the same orientation (with the positive pole
upwards and the negative pole against the battery compart-
ment spring). To maintain water resistance, make sure the
rubber O-ring is in place.
Watch Receiver
The watch receiver has a replaceable battery. However, to
maintain the water resistance of the watch case we recom-
mend taking the watch receiver to a jeweler or watch repair
shop for battery replacement.
Troubleshooting
What if the heart rate reading is erratic or totally absent?
a. Check to see that the chest band is tight enough. The
band should be adjusted so that the electrodes are flat
against your skin. You may have to move the band one way
or another to find the best position for the transmitter.
b. Check to make sure that the electrode strips are thor-
oughly moistened. The transmitter will not function properly
without enough moisture (water or saliva) to make good
electrical contact.
If you are wearing the transmitter over a shirt, make sure
there is enough moisture to make the needed contact with
the electrodes.
Accumulated sweat and dirt may interfere with clear recep-
tion of the signal from the skin to the transmitter. Check to
see if your transmitter needs cleaning.
