Heart Rate Monitor Troubleshooting
If this happens:
No heart rate appears on
the display, or displayed
values are excessive or
vary widely.
Check this:
Is the strap attached to your chest correctly?
Your heart rate cannot be detected
correctly if the strap is not attached to your
chest correctly.
See page E-24.
Are the sensor bars sensor pads (diamond
pattern areas) wet?
Your heart rate cannot be detected if your
skin is dry.
Warm up until you start sweating or
moisten the sensor pads with water.
Are the sensor bars sensor pads dirty?
Dirty sensor pads interfere with stable
heart rate pickup.
Clean the sensor pads as required. To clean
the sensor pads, wipe them with a soft, dry
cloth, or with a cloth that has been moistened
in weak solution of water and a mild neutral
detergent. Wring out all excess liquid from
the cloth before wiping. Never use thinner,
benzene, alcohol, or any other volatile agent
to clean the sensor pads.
Is the sensor bars battery dead?
If so, contact your dealer or CASIO
distributor to have the battery replaced.
Is there some source of electromagnetic
waves (high-tension power lines, TV, cell
phone, etc.) nearby?
Electromagnetic waves can make normal
heart rate detection and communication
impossible.
Possible sources of electromagnetic
waves are: signal equipment, overhead
railway cables, electric bus cables,
streetcars, automobiles, motorcycles,
computers, motorized fitness equipment,
medical devices, electronic security gates,
radios, railway crossings, TV transmitters,
radar sites, etc.
