TROUBLE SHOOTING

BATTERY INSTALLATION

Computer - (Note: Batteries are 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. Similar for sensor battery (Figure

1b).

FUNCTIONS

MOUNTING BRACKET INSTALLATION

Attach the mounting bracket to the left side of the handlebar

with the 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).

SETUP/RESET: In INITIAL SETUP mode you can set WHEEL

SIZE (WS), KM/MILE, 12/24 hour clock and clock time. Press

and hold the LEFT and RIGHT buttons for 4 seconds to

access initial setup mode. The digits on the bottom row will

flash - this is the WHEEL SIZE (WS) setup (note if you have

already programmed wheel size value - the last WS value you

programmed will be displayed).

WHEEL SIZE (WS): Press the RIGHT button to adjust the

value of the first digit of WS. Once you have entered the

correct value press the LEFT button to advance to the next

digit. Repeat for all four digits. Press the LEFT button to

confirm and advance to KM/MILE setup.

KM/MILE SELECTION (12/24): Km/Miles units for distance

and speed will flash. Press the RIGHT button to toggle

between kilometre (KM) and miles (M). Press the LEFT button

to confirm and advance to 12/24 CLOCK setup.

CLOCK (12H/24H): A 12 or 24-hour digital clock is displayed

on the bottom row of the screen. Press the RIGHT key to

toggle between 12 and 24 hour format. Press the LEFT button

to confirm and advance to clock setup.

CLOCK: Press the RIGHT button to advance the hours (hold

RIGHT button for fast advance). Press the LEFT button to

confirm hours. Press the RIGHT button to advance minutes

(hold RIGHT button for fast advance). Press LEFT button to

confirm minutes and exit setup.

ADJUSTING CLK, ODO and WHEEL SIZE (WS) VALUES

AFTER SETUP: CLK, ODO and WS can be changed after

setup. Go to CLK screen. Press and hold LEFT button for 5

seconds. CLK hours will flash. Press the RIGHT button to

advance the hours. Press the LEFT button to confirm hours.

Press the RIGHT button to advance minutes. Press LEFT

button to confirm minutes and enter ODO setup. To adjust

ODO value, press the RIGHT button and then press the LEFT

button to confirm and select the value. Repeat this sequence

to reach the desired odometer value and enter WS setup. To

adjust WS value, press the RIGHT button and then press the

LEFT button to confirm and select the value. Repeat this

sequence to reach the desired WS value and exit setup.

SPEEDOMETER (SPD): Instantaneous Speed is displayed on

the first row. The range of measurement is from 0 to 99KM/hr

(0 to 99M/hr) and accuracy is + /-0.5KM/hr (M/hr).

SPEED TENDENCY : An "up arrow" or "down arrow" icon

appears on the first row to the left of the current speed. An up

arrow indicates you are accelerating. A down arrow indicates

you are decelerating.

AVERAGE SPEED (AVS): AVS is displayed on the second

row. AVS is calculated by dividing TM by DST. To reset AVS,

press and hold the LEFT button for 2 seconds. NOTE: TM,

DST and MXS will also be reset to zero.

MAXIMUM SPEED (MXS): Maximum Speed (MXS) is

displayed on the second row. Maximum speed is stored in

memory and updates only when a higher speed is reached. To

reset MXS to zero, press and hold the LEFT button for 2

seconds.

SPEED COMPARATOR: A "+" or "-" sign appears on the

second line, 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, press and hold the LEFT button

for 2 seconds. NOTE: TM, AVS and MXS 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

7.

TRIP TIMER (TM): Trip Timer (TM) is displayed on the bottom

row. Trip Timer is activated automatically with speedometer

input (when the wheels are turning). It records only the time

spent actually riding. To reset TM to zero, press and hold the

LEFT button for 2 seconds. NOTE: DST, AVS and MXS will

also be reset to zero.

ODOMETER (ODO): Total distance traveled (ODO) is

displayed on the bottom row. To adjust CLK, ODO and WS see

bottom section on page 7

RESET: See top section on page 7.

AUTO START/STOP: The computer will start automatically

(within 1 minute) when your wheels start rotating. In order to

conserve the battery the computer will turn off automatically

after 5 minutes.

WHEEL SIZE (WS): Before you

program your computer you need to

determine your Wheel Size (WS). WS

is the circumference of the front

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. The unit can accommodate WS values

between 100 and 5999 mm.

a) Install the mounting bracket as per page 5.

b) See Figure 2a for position of parts on bicycle.

c) Without using tie wraps - position the sensor on the left

chain stay (or seat stay) and the magnet on a 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 Figures 2c, 2d and 2e. Note the sensor battery cover faces

inwards.

e) Once you have determined the approximate position of the

sensor and magnet - loosely put the cable ties on the sensor

and attach the magnet to the correct spoke. See Figures 2e

and 2f on how to attach the spoke magnet. The magnet

should be maximum 5mm from the sensor.

f) Test out the positioning of the sensor and magnet 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 2d. Once you

have positioned the magnet and sensor properly, tighten up

the sensor cable ties and ensure the magnet is securely

tightened.
