show your current heartbeat rate in beats per minute (BPM) on the LCD after 6~7 seconds. During the process of pulse measurement, the measurement value may be higher
than the virtual pulse rate during the first 2~3 seconds, then will return to a normal level. The measurement value cannot be regarded as the basis of medical treatment.
The computer has a countdown function for TIME, DISTANCE, and CALORIES. To use the countdown function, press MODE to select TIME, DISTANCE, or CALORIES. Press SET to set the value, and then you can start pedaling. The computer will countdown from the value you set. When the countdown is done, it will automatically start counting from 0.
