OPERATION FEATURES
Two buttons are provided on the top of the main unit and two on the bottom.
These buttons are used as follows:
•Mode Button (top left button)
Whenever this button is pressed, the mode display changes in the order
shown in fig.1, and the data is displayed on the sub-display. Note: If this
button is kept pressed for more than 2 seconds, display appears.
•Start/Stop Button (top right button)
Measurement of trip distance, elapsed time and average speed is started or
stopped when the start/stop button is pressed. Whenever this button is
pressed, start and stop are repeated. During measurement the speed scale
symbol blinks.
Note: This button does not function if the auto mode function is set to ON
[Refer to the explanation of the Auto (Automatic Start/Stop) Function below].
•Set Button (bottom left button)
• To set the wheel circumference:
Stop the measurement in the (O) mode, then press the SET button.

Stop the measurement in ( ) mode, then press the SET button.
• To set auto mode to ON or OFF:
Select the (T),(A) or (D) mode, then press the SET button.
•AC (All Clear) Button (bottom right button)
When this button is pressed, all the data stored in memory is cleared.
After all displays illuminate, the "mile/h" symbol illuminates. This button should
be pressed only after replacing the battery or when irregular display of infor-
mation occurs due to static electricity,etc. Once this button is pressed and all
memory is erased, it will be necessary to set the wheel circumference, time,
etc. again. (refer to Main Unit Preparation)
Reset Operation: (Fig.2)
Press left button to select any mode except total distance (O) and press left
and right buttons together. Stored data of trip distance (D), elapsed time (T),
average speed (A) and maximum speed (M) are all reset to zero. (In the total
distance display mode, the current wheel circumference (A) or (B) is shown.)
MAIN UNIT PREPARATION
User must make the following setting according to instructions before
the cyclocomputer can be used properly.
1. How to measure the exact Wheel Circumference (L)(Fig.3)
First, adjust tire pressure and then put a mark on the tire tread and the ground
simultaneously. Then ride the bike one full wheel revolution. Mark the ground
at the end of one revolution and then measure the distance between the two
marks. This measure is your actual wheel circumference. Or, the "Setting Val-
ues Cross Reference Table" can help you to find out an approximate wheel
circumference according to tire size.
2. Setting the Speed Scale (Fig.4)
When the AC button is pressed and all displays illuminate then the "mile/h"
appears as shown in fig.4. "km/h" and "mile/h" are displayed alternatively each
time the right button is pressed. Select any speed scale as desired and press
SET button to complete the setting.
3. Setting the Wheel Circumference (Fig.5.6)
This cyclocomputer is able to memorize two different wheel circumferences.
One main unit can be used on two bicycles subject to buy another set of
bracket and sensor.
Two wheel circumferences, (A) 2155mm and (B) 2030mm, have been set be-
fore the cyclocomputer left our factory. The (A) wheel circumference 2155mm
(standard for 27 inch tire) will blink as shown in fig.5. If you want to enter
2155mm and 2030mm, simply press the SET button. If you want to change,
press either the right button to increase or left button to decrease the number.
To change the number rapidly keep the button pressed. Once you reach the
setting you want, press the SET button. If you want to set a second circumfer-
ence, press the left and right buttons together before pressing the SET button.
The wheel circumference 2030mm is displayed and blinks(fig.6). Set to a de-
sired wheel circumference in the same manner as the first circumference set-
ting and press SET button to complete the setting.
4. Selecting one of the two Wheel Circumference (Fig.7)
Set the Auto Mode to ON. (Refer to the explanation of Auto Mode function.)
While keeping the right button pressed , press the SET button. The first wheel
circumference measurement will be displayed for a few seconds, then the sec-
ond setting will appear.
5. How to reset the Wheel Circumference
Select the (O) mode and stop the measurement. Press SET button and the
already set wheel circumference will blink on the sub-display. Refer to '3.Set-
ting the wheel circumference' to complete the setting.
Setting the 24-hour Clock (Fig.8)
Press left button for more than 2 seconds to select the 24-hour clock display.
Stop the measurement by pressing the right button. Press SET button and the
minute display will start to blink. Press right button to select a minute time
ahead of the current time by 1 to 2 minutes. Next press left button and the hour
will blink. Press right button to set to current hour time. Press SET button to
complete the setting.
MOUNTING TO BIKE
If necessary, use either the 1mm or 2mm thick rubber pads according to the
handlebar diameter. Mount the bracket as shown in fig.9.
• Slide the main unit onto the bracket from front until it clicks into position. To
remove the main unit, pull it forward while depressing the lever on bracket
(fig.10).
How to Mount the Sensor on the Right Front Fork Leg.(fig.11)
Mount the sensor in the highest possible position on the right front fork leg.
Adjust the position, clearance and direction as follows:
(1) Insert the band B into the slit of the band A, and put the rubber pad inside
of the band A (fig. 12). Adjust the length of the bands in order that the
screw-fastening part of the bands is parallel when mounted to the fork (fig.
13). * To pull out the band B from band A, tug strongly.
(2) Mount the adjusted bands to fork along with the sensor, by temporarily
tightening the screw (fig. 14).If the space between front fork and spoke of
your bike is big, use the spacer and long screw as in the fig.15, so that the
clearance between sensor and magnet will be approx. 5mm.
(3) Use a coin to install the magnet securely to the spoke so that it face the
sensor zone.(fig.16 & 17)
(4) A 5mm clearance shall be kept between the sensor and magnet(fig.18).
Then align the magnet with sensor zone (fig.16). Meanwhile, the sensor
shall aim at the main unit indicated by the triangle marked on the sensor.
Then tighten the screw to secure the sensor in position. Cut the excess
sensor band B with scissors or the like.

TEST
Mount the main unit on the bracket. If current speed doesn't appear on the
main display, press either left or right button to release the unit from the power
saving mode. Then spin the front wheel to make sure the wheel sensor pulse
symbol flickers. If it does not flicker, adjust the position of sensor until it flickers
normally. The mounting is completed and the cyclocomputer is operational.
THE CORDLESS SYSTEM
The sensor picks up wheel revolution signal and transmits the signal to the
receiver in the main unit. The main unit receives, calculates and displays the
data. The approximate service hour of batteries is as follows:
The main Approx. 2 years (average 1 hour's use per day)
The sensor (transmitter): ------- Total distance of approx. 10,000 miles (16,000 km)
Note: To prevent external signal interference, the sensor signal reception
range is restricted. For best performance, the triangle mark
on the sensor shall
aim at the direction to the main unit. The distance between the sensor and main
unit must be kept within 45 cm. The signal reception range may shorten as a
result of low ambient temperature or lowered battery power. It is advisable to
replace the sensor battery before it fails. The battery service hours quoted
above is the average for a 45cm distance between the sensor and main unit.
• The cordless system may be interfered with in the following situation, so that
main unit may display false data.
1. Riding near railroad crossings and trains.
2. Riding in places where intensive electromagnetic wave or field exist,
such as TV transmission station and radar installations.
3. When two bicycles carrying similar cyclocomputers are ridden side by
side.
REPLACING THE BATTERIES
Batteries are already loaded in the main unit and the sensor.
How to replace battery in Main Unit (Fig.20)
Open the battery cover on the back and insert a new CR2032 (lithium) with the
(+) pole upward, while pressing the side of the battery against the contact.
Press AC button to erase all stored data and then redo the settings.
How to replace battery in Sensor (Fig.21)
Take off the sensor from the bicycle. Open the battery cover on the back and
insert a new CR2032 (lithium) with the (+) pole upward, while pressing the side
of the battery against the contact. Mount the sensor back to the bicycle and
adjust to relative position, clearance and direction.
