If there are problems in pulse measurement:
:: Check how the sensor works while not pedalling.
:: A disturbance may be caused by the physiological properties of the
earlobe. Try measuring on the inside surface of the ear or on
the tip of your finger.
:: Rub the earlobe with your fingers to quicken circulation.
:: If pulse values rise above 150 beats/min., earlobe measurement
may be affected by the faster circulation.
:: Sometimes a strong light source in the immediate vicinity of
the user may cause disturbances.
Please clean the ear sensor after use with a damp cloth. Do not use
solvents.
NOTE! Always detach the ear sensor connector from the user interface
when you use the heart-rate belt. The ear sensor disturbs heart-rate
measurement.
3.2 Measurement with an ear sensor
You can buy the ear sensor needed for pulse measurement from your
Tunturi dealer or importer as an accessory.
Measure your pulse as follows:
1. Open the cover at the back of Alpha 200 and pushing the ear
sensor connector into the interface connector. Lead the ear sensor
wire out through the hole between the cover and the box, and
close the cover.
2. Attach the ear sensor to the earlobe.
3. Attach the sensor wire to your shirt with the clip provided. This
prevents the sensor and wire from moving.
