®
Telemetry Heart Rate Chest Strap
Heart Rate Reading Is Initially Detected then Lost or Abnormally Elevated
Malfunction
Probable Cause
Corrective Action
Heart rate reading is initially
detected and functioning nor-
mally but then is lost.
Use of personal electronic
devces, such as cell phones
and portable MP3 players, caus-
es external noise interference.
Remove the source of noise or
reposition the exercise
equipment.
Equipement is in close proximity
to other sources of noise such
as audio/ video equipment,
fans, two way radios, and high
voltage/highcurrent power lines.
Heart rate readings are
abnormally elevated.
Television sets and/or
antennas generate electromag-
netic interference.
Move the treadmill a few inches
away from the probable cause,
or move the probable cause a
few inches away from the tread-
mill, until the heart rate readings
are accurate.
Cell phones generate electro-
magnetic interference.
Computers generate electro-
magnetic interference.
Cars generate electromagnetic
interference.
High voltage power lines gener-
ate electromagnetic interfer-
ence.
Motor driven exercise equip-
ment generates electromagnetic
interference.
Another heart rate transmitter
within three feet (one meter)
generates electromagnetic inter-
ference.
