ACCESSORIES

ATTACHING THE RECEIVER UNIT TO THE HANDLEBAR

Step 1 : Put the Unit onto the Handlebar

Step 2 : Mounting Shoes

Attach the mounting shoes to the handlebar using the bracket screw

provided. If the clamp closes completely, or the bracket slips on the

handlebar, rubber shims are included to provide secure fit.

MAGNET MOUNTING

ATTACH THE MAGNET TO THE LEFT SIDE FRONT WHEEL SPOKE WITH THE

SCREW PROVIDED. OVER TIGHTENING THE SCREW CAN STRIP THE

THREADS. SO USE CAUTION.

POSITION THE TRANSMITTER AND MAGNET AS SHOWN, MAKE SURE

THE ARC OF THE MAGNET INTERSECTS THE TRANSMITTER'S 'SENSOR'

MARKING WITH , 2MM CLEARANCE, ADJUSTING THE DESIRED GAP BY

MOVING BOTH THE MAGNET AND THE TRANSMITTER UP AND DOWN.

Battery Installation

Remove the battery cover with a coin. InstaIl the battery with the positive ( + ) side

facing the cover and replace the cover.

Initial Setting Mode (System Reset)

The cyclocomputer can be reset anytime by depressing both buttons together over 2

seconds or after battery installation. At reset, the screen shows all segments ON for 2

seconds and data in all modes are CLEARED instantly. The initial setting mode is

then entered.

KM/MILE SELECTION

The screen shows flashing "M/H" (mile per hour). Press the left button to change

from "M/H" to "KM/H" (kilometer per hour) or vice versa. Press the right button to

confirm the selection.

AUTO/MANUAL TIMER SELECTION

The screen shows" AUTO" which indicates the timer operating in Auto mode (Auto-

timer). Press the left button to change from " AUTO" to Manual mode (Stopwatch) or

vice versa. Press the right button to confirm the selection. If Auto-timer is operated,

"AT" will be shown on the screen after the initial setting.

WHEEL SIZE INPUT

The screen shows a four-digit wheel size (wheel circumference in mm), with

the last digit flashing. Press the left button to advance the digit or depress it

over 2 seconds for fast advance. Press the right button to confirm the digit

setting and switch to the next digit setting. The input is finished after the first

digit has been confirmed. The wheel sire is ranging from 0000 to 2999mm

with a default value of 2124.

Cyclocomputer Functions

The cyclocomputer has Speedometer shown on the top line and one of six functional

modes shown on the bottom line at a time, which are Odometer, Tripmeter, Timer,

Clock, Average speed and Maximum speed. To change mode, simply press the right

button after exiting the initial setting mode. To check for proper speed function and

sensor alignment, spin the front wheel.

Power saving function

Power saving function is activated whenever there is no further key input and wheel

spinning for around 4 minutes. At this time, the clock is shown on the screen. Press

any button or spin the wheel to return to normal state.

Speedometer

Speedometer is shown on the top line all the time. The current speed updated every

3 seconds is displayed. (Note: The speedometer has a range of 0.0 to 99.9 km/h or

mile/h with a resolution of 0.1 km/h or mile/h.)

Odometer mode

Odometer mode is indicated by "ODO". The accumulated distance travelled in every

trip since the last system reset is displayed. To change the timer operating mode or

wheel size, depress the left button over 2 seconds. (Note: The odometer has a range

of 0.0 to 9999.9 km or mile and a reset value of 0.0. It overflows to 0.0.)

Tripmeter mode

Tripmeter mode is indicated by "DIS". The distance traveled since the last reset is

displayed. It counts the distance only when the timer is running. To reset the

tripmeter, depress the left button over 2 seconds. At the same time, the timer, the

average speed and the maximum speed are also reset. (Note: The tripmeter has a

range of 0.00 to 999.99 km or mile and a reset value of 0.00. It overflows to 0.00 and

resets the timer, the average speed and the maximum speed.)

Timer mode

Timer mode is indicated by "TM". The time kept since the last reset is displayed.

When operated as Auto-timer, it starts/stops automatically by motion of bicycle.

When operated as Stopwatch, it starts/stops by pressing the left button. To reset the

timer, depress the left button over 2 seconds. At the same time, the tripmeter, the

average speed and the maximum speed are also reset. (Note: The timer has a range

from 0:00:00 to 9:59:59 and a reset value of 0:00:00. It overflows to 0:00:00 and

resets the tripmeter, the average speed and the maximum speed.)

Clock mode

Clock mode is indicated by "CLK". The 24-hour clock is displayed. To set the clock,

depress the left button over 2 seconds and then release it. Press the left button again

to advance the flashing minute or depress it over 2 second for fast advance. Press

the right button to confirm the minute set and repeat the procedures to set hour.

Press the right button again to confirm the hour set and the clock setting is finished.

Average Speed mode

Average Speed mode is indicated by " AVS". The average speed since the last reset

is displayed. It is updated every ten-second count of the timer. The average speed is

reset to 0.0 km/h or mile/h once the tripmeter or timer is reset or overflows.

(Note: The average speed has a range of 0.0 to 99.9 km/h or mile/h and a reset

value of 0.0)

When the cycling speed is slow (about 10 km/h or below), the LCD sometimes

displays "00", because the sensor is less sensitive at very low speed. The display

reverts to the correct speed again. *See Important Note at back of manual *

Maximum Speed mode

Maximum Speed mode is indicated by "MXs". The maximum speed since the last

reset is displayed. The maximum speed is reset once the timer or the tripmeter is

reset or overflows.

(Note: The maximum speed has a range of 0.0 to 99.9 krn/h or rnile/h and a

reset value of 0.0.)

Different Speed mode

Different Speed mode is indicated by "DIF". Push mode key (right key) to reach this function.

The lower display will show the different speed between the current speed and Ibe average

speed (+/-).

(Note: The Different speed has a range of -150.0 to 150.0 km/h (or mile/h)

and a rest value of 0.0)

Scan function

Scan function mode is indicated by "SCAN". Push mode key (right key) to reach this function

after Different Speed function. SCAN icon will show and the lower display will show values of

ODO, DIS, TM, CLK, AVS, MXS and DIF in sequence change every 6 seconds.

Trouble Shooting

TROUBLE POSSIBLE CAUSE

Speedometer always reads Improper magnet/sensor alignment, check

zero when cycling. magnet/sensor mounting.

Slow display response. The cyclocomputer has been operating at a

temperature below 0°C, it returns to normal

state when temperature rises.

LCD is black. The cyclocomputer has been exposed to the

sun for a long time, place it in the shade to

return to normal state.

Display readout fades. Poor battery contacts or dead battery, check

battery installation or replace battery.

Important note

Before starting a new trip, the user can clear the values of the previous trip by pushing the

MODE switch until the DIS icon is shown. Push down the Mode switch (left switch) and hold

until the DIS value is reset to zero. The value of AVS at this stage can be ignored. As the

user embark on a new cycling trip, all new values of DIS, DIP, TM, AVS and MXS will be

calculated and displayed.

Safety Precautions

- PIease dispose the BATTERY UNIT in an environmentally friendly manner in accordance

with the relevant legislation.

- Replace only with the same or equivalent type of battery recommended by the

manufacturer.

- Not to be exposed dripping or splashing.
