SCAN mode), hold SET for 2 seconds to reset the val ue of DST( distanc e), RT M(ridin g time) , AVS( ave rage sp eed ), RES( rel ativ e s peed), MXS(max. speed), and enter SCAN mode.

2.The measurement begins once riding on the bicycle. If the computer receive no signal during riding, the " " in the display will not flash. Stop riding and check if the magnet place well, if the sensor got enough power.

3.Press MODE to select the display mode or SCAN mode. Each display will be changed in order each 4 seconds when in SCAN mode.

4.The computer will turn off automatically if there is no operation or signal over 8 minutes, and all the memory will be kept. You can press any button to turn on the computer to receive the signal again.

HOW TO WEAR THE CHEST BELT (FOR MODEL JS-204A/JS-212A)

In order to get correct heart rate signal, you need to properly wear the chest belt (FIG.O). The chest belt will transfer the data to the bicycle computer .

A. Shorten the distance between the transmitter

and receiver. B. Re-adjust the position of the transmitter. C. Check the batteries. Replace them when necessary.

HEART RATE MEASUREMENT (FOR
