TELEMETRY HEART RATE CHEST STRAP
Malfunction Probable Cause Corrective Action
Heart rate reading is initially
detected and functioning
normally but then is lost.
Use of personal electronic
devices, such as cell phones
and portable MP3 players,
causes external noise
interference.
Remove the source of noise

to other sources of noise such
as audio/ video equipment,
fans, two way radios, and high
voltage/high current power
lines.
Heart rate readings are
abnormally elevated.
Television sets and/or
antennas generate electro-
magnetic interference.
Move the Bike a few inches
away from the probable cause,
or move the probable cause a
few inches away from the Bike,
until the heart rate readings are
accurate.
Cell phones generate
electromagnetic interference.
Computers generate
electromagnetic interference.
Cars generate electromagnetic
interference.
High voltage power lines
generate electromagnetic
interference.
Motor driven exercise
equipment generates electro-
magnetic interference.
Another heart rate transmitter
within 3 feet (1 meter)
