COMPUTER DISPLAY AND FUNCTIONS

DISPLAY: There are three main screens. Press the RIGHT
button to toggle between the three display screens.
Screen 1 Screen 2 Screen 3
SPEEDOMETER (SPD): Instantaneous Speed is displayed on
the second row. The range of measurement is from 0 to
99KM/hr (0 to 99M/hr) and accuracy is + /-0.5KM/hr (M/hr).
SPEED COMPARATOR: A "+" or "-" sign appears on the
second row, to the right of the SPD icon. A "+" indicates you
are traveling faster than your average speed (AVS). A "-"
indicates you are riding slower than your average speed.
TRIPOMETER (DST): Trip distance (DST) is displayed on the
third row. DST is accumulated automatically with speedometer
input. To reset DST to zero, go to DST screen (SCAN OFF),
press and hold the LEFT button for 2 seconds. NOTE: TM and

d) Cadence Sensor - Locate the cadence sensor (sensor with short wire). Without using
cable ties - position the cadence sensor on the outside face of the left chain stay and the
cadence magnet on the inside of the left crank. Position the sensor and magnet in such a
way so that the magnet passes over the right portion of the sensor as shown in figure 5a
and 5b.

f) Cadence Sensor Test out the positioning of the cadence
magnet and sensor by rotating the cranks backwards to see if
the computer registers a cadence value. If no value is
registered reposition the sensor and magnet again. Make sure
the magnet passes over circle arrow on the cadence sensor as
shown in Figure 5c. Once you have positioned the magnet and
sensor properly - tighten up the cadence sensor and cadence
magnet cable ties securely and clip off the ends.
g) Speed Sensor - Locate the speed sensor (sensor with long
wire). Without using tie wraps - position the speed sensor on
the inside face of the left chain stay and the speed magnet on
a rear wheel spoke. Position the sensor and magnet in such a
way so that the magnet passes over the circle arrow on the
sensor as shown in figure 5a and 5d.
h) Speed Sensor - Once you have determined the
approximate position of the speed sensor and magnet -
loosely put LARGE cable ties on the speed sensor and attach
the speed magnet to the correct spoke. See Figures 6a and
6b on how to attach the speed spoke magnet. The magnet
should be maximum 2mm from the speed sensor.
