BATTERY INSTALLATION
Computer - (Note: Battery is pre-installed) Remove the
battery cover from the bottom of the computer using a small
coin. Install the 3V battery with positive (+) pole facing the
cover (Figure 1a). If the LCD shows irregular figures, take out
the battery and install again. This will clear and restart the
computer's microprocessor.

MOUNTING BRACKET INSTALLATION
5
Attach the mounting bracket to the right side of the handlebar
with the large cable ties (Figure 3a and 3b). Make sure the
mounting bracket is clamped tightly and will not slip on the
handlebar. Slide the computer onto the mounting bracket until
it snaps firmly into position. Press the release button to
remove the computer (Figure 3c).
SENSORS INSTALLATION
Fig. 4a
Fig. 4b
a) See Figure 4a and 4b for routing of sensors wire.
b) Make sure that there is enough wire clearance so the
handlebars can rotate fully in both directions without pulling at
the sensors wire.
c) Route the wire down the frame of your bike and to the left
chain stay. Do NOT install cable ties yet.

e)
Cadence Sensor -
Once you have determined the
approximate position of the cadence sensor and magnet -
loosely put LARGE cable ties on them. The magnet should be
maximum 2mm from the cadence sensor and magnet. Note:
for cranks arms that are hollow, you may need to put a spacer
(not included) behind the cadence magnet to hold it in place. A
small piece of foam or rolled up black electrical tape will work.
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.
i)
Speed Sensor -
Test out the positioning of the speed
magnet and speed sensor by rotating the rear wheel to see if
the computer registers a speed value. If no value is registered
reposition the sensor and magnet again. Make sure the
magnet passes over circle arrow on the speed sensor as
shown in Figure 5d. Once you have positioned the magnet and
sensor properly, tighten up the speed sensor cable ties and
ensure the spoke magnet is attached securely.
j) Secure the rest of the wire securely to the frame of your
bicycle with the remaining cable ties. Make sure that there are
no dangling wires.

WHEEL SIZE (WS):
Before you
program your computer you need to
determine your Wheel Size (WS). WS
is the circumference of the rear wheel
in mm. This value is entered into the
computer in order to calculate speed
and distance.
While charts provide a quick and easy
way to get WS, there are no standard
wheel sizes in the cycling world - i.e.
the circumference (or Wheel Size =
WS) of a 700x23 tire will differ from
one brand of tire to another - so for
accurate speed and distance values
on your computer you need to
measure your wheel circumference.
To obtain WS:
Method 1
: Fast (and not so accurate)
method - use chart provided.
Method 2
: Most accurate method:
a) See Figure 8.
b) Inflate your tires to their proper
pressure.
c) Put a mark on your rear wheel on the outside
circumference.
d) Put a mark on the floor.
e) Put the mark on the wheel on the mark on the floor.
f) Rotate the wheel one full revolution until the mark on the
wheel is on the floor again. Mark this location.
g) Measure the distance between the marks on the floor in
mm. This is the Wheel Size (WS) (i.e. your wheel
circumference in mm).
h) Write this number down. The value should be between
1800 and 2200 mm for standard size tires. The unit can
accommodate WS values between 100 and 5999 mm.

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
AVS will also be reset to zero.
AVERAGE SPEED (AVS):
Average Speed (AVS) is displayed
on the third row. AVS is calculated using the Trip Timer and
Tripometer (AVS = DST/TM). To reset AVS to zero, go to AVS
screen (SCAN OFF), press and hold the LEFT button for 2
seconds. NOTE: TM and DST will also be reset to zero.
CLOCK (CLK):
A 12/24 hour clock is displayed on the third
row. To adjust CLK, ODO and WS see bottom section on page
10.
MAINTENANCE REQUIRED FUNCTION:
The Maintenance
Required Function lets you know when you need to do
scheduled maintenance on your bicycle - for instance re-oil
your chain after a pre-set distance is reached. The
Maintenance Require Icon ( ) will appear when maintenance
is required. During setup you can set the preset maintenance
reminder function to 200, 400, 600 or 800 miles (or Km). If 600
KM is chosen, the wrench will flash every 600, 1200, 1800 KM
(or miles), etc. Press the LEFT button to stop the wrench ( )
from flashing.

TRIP TIMER (TM):
Trip Timer (TM) is displayed on the bottom
row. Trip Timer is activated automatically with speedometer
input (when the rear wheel is turning). It records only the time
spent actually riding. To reset TM to zero, go to TM screen
(SCAN OFF), press and hold the LEFT button for 2 seconds.
NOTE: DST and AVS will also be reset.
MAXIMUM SPEED (MXS):
Maximum Speed (MXS) is
displayed on the bottom row. Maximum speed is stored in
memory and updates only when a higher speed is reached. To
reset MXS to zero, go to MXS screen (SCAN OFF) press and
hold the LEFT button for 2 seconds.
ODOMETER (ODO):
Total distance traveled (ODO) is
displayed on the bottom row. To adjust CLK, ODO and WS see
bottom section on page 10.
SCAN MODE (SCAN):
Scan mode allows you to see all
screens without pressing any buttons, each screen will be
displayed for 4 seconds. Press the RIGHT button until the
SCAN icon is displayed on the left hand side of the 2nd row.
Press the RIGHT button to stop SCAN mode - note SCAN
mode is ON only when SCAN is shown on the screen.
