Precautions
• Don't pay too much attention to your computer functions while riding. Keep your eyes on the
road and give due consideration to safe riding.
• Securely attach the magnet, sensor and bracket to your bicycle. Periodically check if the screws
and secure bands have loosend.
• Safely dispose of the old battery. Do not place it within children's reach. If swallowed by mistake,
consult a doctor immediately.
• Do not leave the main unit exposed to direct sunlight. Never disassemble the main unit.
• For cleaning, use neutral detergent on soft cloth, and wipe off with dry cloth. Do not apply paint
thinner, benzine or alcohol, to avoid damages on the surface.
• If there is mud, sand or the like clogged between the button and the body, the movement of the
button may be deteriorated. Softly wash away such objects with water.
Spd Current Speed
0.0(3.0) - 65mph ± 1 mph (under 31 mph) [0.0(4.0) - 105 km/h ± 1 km/h]
Aways displayed on the upper display and updated once a second.
Average Pace Arrow
Shows whether the current speed is faster or slower than the average speed
----- Faster than the average speed
----- Slower than the average speed
Odo Total Distance (Odometer) 0.0 - 9999.9 mile[km] ± 0.1 mile[km]
Continuously measured until battery wears down. At 9999.9 km, it returns to zero
and counting begins anew. (With all clear operation, it return to zero; to continue
accumulation of data, input the previous Odo data after all clear operation.)
Dst Trip Distance 0.00 - 999.99 mile[km] ± 0.01 mile[km]
The trip distance from start to current point is displayed. With reset operation, it
returns to zero.
Tm Elapsed Time 0:00'00" - 9:59'59" ± 0.003 %
Elapsed time is measured from start to current point, in units of hours, minutes and
seconds. At 10 hours, it returns to zero and counting begins anew. With reset opera-
tion, it returns to zero.
Av Average Speed 0.0 - 63.0 mph[99.9km/h] ± 0.3 mile[km]
The average speed from start to current point is displayed. If the elapsed time ex-
ceeds 10 hours, (.E) is displayed and calculation ceases.
Clock time 1:00' - 12:59' or 0:00' - 23:59' ± 0.003 %
If "Mile" is selected for scale symbol, the clock time is in 12 -hour. If "Km", the clock
time is 24-hour.
Power Saving Function
When the main unit does not receive a signal, or a button has not been pressed for
1~2 hours, the power supply is shut down and the main unit will only display the
clock . By pressing the Main button, or by receiving signal, this function is re-
leased.
Trouble Shooting
No display.
Has the battery in the main unit worn out?
Replace it with a new one.
Incorrect data appears.
Do "All Clear" operation.(If possible, write down the Odo data before all clear operation, and
input it again after the display returns normal.)
Current speed does not appear. (When current speed does not appear, first short-circuit the
contact on the back with metal; if the speed display appears, the main unit is normal and the
problem must be in the bracket or the sensor.)
Is there anything on the contact of the main unit or of the bracket?
Wipe the contact clean.
Is the distance between the sensor and the magnet too far?
Are the marking line of the sensor and the center of magnet aligned?
Adjust the position of the sensor and magnet again.
Is the wire broken?
Replace it with a new one.
Current speed does not appear in wet condition.
Wipe the contacts with dry cloth. Contacts can also be treated with a water repellent silicon
jell from an automotive parts store or hardware store. Do not use industrial water repellent; it
may damage the bracket.
When "Mile" was chosen for speed scale,
the clock time is in 12-hour
time is 24-hour
How to Replace Battery
In order to continue accumulation of Odo data, write down the stored
Odo data before replacing the battery. Insert a new lithium battery
(CR2032) with the (+) pole upward.
Continuing Accumulation of Odo Data
Although the Odo data returns to zero by all clear operation, you can
continue accumulation of data by inputting the previous Odo data. Be
sure to write down the data before replacing the battery.

clearance between the
magnet and sensor. Tem-
porality attach the sensor to
the fork with the self-adhe-
sive patch.
Test
Slide the main unit onto the bracket
according to “How to Attach Main
Unit to Bracket” (below). Spin the
front wheel and check if the velocity
indicator is spinning. (If not, adjust
the relative positions of the magnet
and sensor again.) After the test, re-
move the main unit.
Fix the sensor with the nylon ties.
Note: Fasten the ties securely.
Secure the wire along the fork
with the nylon ties, and wind it
round the brake cable up to the
handlebar.
Note: Allow enough wire length
in the area marked with
in the illustration, to
insure full movement and
unhindered operation of
the handlebar.
