Heart Rate Monitor Troubleshooting
If this happens:
No heart rate appears on
the display, or displayed
values are excessive or
vary widely.
Check this:
첸
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.
첸
Are the sensor bar’s 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.
첸
Are the sensor bar’s 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.
첸
Is the sensor bar’s battery dead?
• If so, contact your dealer or CASIO
distributor to have the battery replaced.
첸
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.
