Procedure
1. On C846 version 1 units, set the on/off switch in the “on” position. It will be necessary to
start pedaling for the bicycle to “power up”. You must continue pedaling while performing

hold the RESET key to continue.
7. Power bits indicates the amount of power required to pedal the bike. The power bits are
adjustable between 0 and 255 by using the
or keys. The greater the power bits
number the greater the pedaling resistance. Press ENTER to toggle the display between
power bits and speed. Press the RESET key to continue to the heart rate test.
8. The left side of the window displays a “U F P”. the right side displays the heart rate, when a
signal is received from a chest strap or test transmitter. The U indicates unfiltered, the F
indicates filtered and P indicates Polar. The ENTER toggles through the three choices.
When unfiltered is selected the heart rate display will show heart rate as received from the
transmitter. When filtered is selected the heart rate signal will be averaged and displayed.
When Polar is selected, the Polar method of filtering will be used and the results displayed.
The Polar method of filtering is used during normal operation. Press and hold the RESET
