ROUBLESHOOTING
Dry skin or very hairy arms
Use a conductive paste or wet your fingers and wrist.
Your finger does not have proper contact with the sensor
Your finger (not only the finger tips!) has to lie flat and firmly on the
metal casing and the monitor has to be strapped skin-tightly to your
wrist.
Irregular heartbeat
A correct heart rate measurement is very difficult in this case, irregu-
lar measurement periods can be expected. The result will not be
reliable in all cases!
Movement during the pulse measurement
Avoid moving intensively during the pulse measurement to get a
reliable result.
