Precautions
• Don't pay too much attention to your computer functions while riding. Keep your eyes on
the road and pay attention to traffic conditions.
• Securely attach the magnet, sensor and bracket to your bicycle. Periodically check if the
screws and secure bands have loosened.
• 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, button opera-
tion can become impaired. Softly wash away such objects with water.
• Before each ride, insure the computer is completely and securely mounted to the
bracket.

HOW TO A
All Clear Operation
Press all the three buttons simultaneously.
All displays illuminate, and then "K " symbol flashes.
Speed Scale Selection
Press MODE button and select "K"(=km) or "M"(=mile).
Wheel Circumfer
Input wheel circumference
by S button (– ) or MODE button (+).
For inputting wheel circumference B, hold down SET button;
the display changes to B. Input the figure in the same way.
Press S or SET button to fix it

Spd Current Speed
Wheel A: 0.0(3.0)-65 mph ± 1 mph(under 31 mph)[0.0(4.0)-105km/h ± 1km/h]
Wheel B: 0.0(2.0)-65 mph ± 1 mph(under 31 mph)[0.0(2.5)-105km/h ± 1km/h]
Usually displayed on the upper display and updated once a second. When Av
or Mx data is shifted to the upper display, Spd shifts to the lower display.
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
When the average speed is zero, or when in the stop state, no pacer
symbol appears.
Odo Total Distance (Odometer)
0.0 - 9999.9 /10000 - 99999 mile[km] ± 0.1 mile[km]
Continuously measured until battery wears down. Displayed with 0.1
resolution up to 9999.9 km and with 1.0 resolution up to 99999 km. (With
all clear operation, it returns to zero; to continue accumulation of data,
input the previous Odo data after all clear operation.)
Dst(1, 2) Trip Distance(1, 2)
0.00 - 999.99 mile[km] ± 0.01 mile[km]
The trip distance from start to current point is displayed. Two different
start points can be set (Dst1 and Dst2). Dst2 is best for measuring a sec-
tional distance. With Reset operation, it returns to zero. [Reset of Dst1 is
always done with reset of Tm, Av and Mx all together. Reset of Dst2 is
done independently of the other reset and does not affect the other data.]
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 the press of S button, Tm data shifts to the upper display. In
this case, the lower display shows the hour digits of Tm data (instead of
Spd). With Reset operation, it returns to zero.
Av Average Speed
0.0 - 65 mph [105 km/h] ± 0.3 mph [km/h]
The average speed from start to current point is displayed. If the elapsed
time exceeds 27 hours or Dst1 exceeds 999.99km, (.E) is displayed and
calculation ceases. With the press of S button, Av data shifts to the upper
display. In this case, Spd data is shifted to the lower display. With reset
operation, it returns to zero.
Mx Maximum Speed
0.0(3.0) - 65 mph [105 km/h] ± 1 mph [km/h]
Displays the highest recorded speed. With the press of S button, Mx data
shifts to the upper display. In this case, Spd data is shifted to the lower
display. With reset operation, it returns to zero.
Clock time
1:00' - 12:59' or 0:00' - 23:59' ± 0.003 %
If "M" is selected for speed scale, the clock time is in 12 hour. If "K", the
clock time is 24 hour.
Automatic Start/Stop Function
When the symbol is on, the unit automatically starts and stops measuring while a wheel
pulse is detected. (See the above “ In Measuring Functions” for how to switch on/off .)
Power Saving Function
When the main unit does not receive a signal, or a button has not been pressed for 60-70
minutes, the power supply is shut down and the main unit will only display the clock. By
pressing either MODE or S button, or by receiving signal, this function is released.
Maintenance
When the main unit or the contact gets wet, dry it off with a cloth; rust will cause functional
errors.
Trouble Shooting
No display.
Has the battery in the main unit worn out?
Replace it with a new one.
Incorrect data appears or the screen is frozen.
Do "All Clear" operation. (If possible, write down the Odo data before all clear opera-
tion, 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. DO NOT use abrasives, sandpaper, etc.
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.
When "M" (=Mile) was chosen for speed
scale, the clock time is in 12-hour. If "K"
(=Km), the clock time is 24-hour.
How to Replace Battery
Insert a new lithium battery (CR2032) with the (+) pole upward. Per-
form ALL CLEAR OPERATION after replacing the battery.
In order to continue accumulation of Odo data, write down the stored
Odo before replacing the battery.
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.
