TROUBLE SHOOTING – HEART RATE
INTERFERENCE
Heart rate monitors are subject to interference from a wide range
of external sources of electromagnetic and microwave radiation.
High tension power lines, home and automotive electronics, exercise
equipment, home security systems, traffic light controls, airport radar
systems and other things are capable under the right conditions of
blocking the heart rate transmission system. When this happens, the
user will usually notice a very heart rate reading (200+ ) or a reading
of zero. Usually sources of interference are localized and the unit will
return to proper operation in a few seconds or at most minutes.
CROSS TALK (USING CHEST STRAP TRANSMITTER)
Exercising in close proximity to other people using heart rate monitors
may cause your watch to pick up signals from chest straps other than
your own. This is known as Cross Talk. To avoid problems associated
with Cross Talk it is recommended that you separate yourself from
others wearing heart rate monitors by a minimum of 3’ or 1m in all
directions.
TRANSMISSION RANGE
(USING CHEST STRAP TRANSMITTER)
The heart rate monitor system has an effective range of 28-30 inches
(.75 meters). If the monitor is separated from the transmitter strap by
a greater distance than this, you may not be able to receive a heart
rate signal. Additionally, the orientation of the watch and transmitter
must be such that the reading direction of watch face is not aligned
perpendicular to the transmitter. Having the system in this orientation
will significantly reduce the units range.
