TROUBLE SHOOTING

The following situations do not indicate malfunction of the cyclocomputer. Check the following before taking to repair. * When current speed does not appear, short-circuit the contact on the back with metal. The unit will function normally if the speed display appears. Display response is slow. ----- Is it at a low temperature under 32F(0C)? ----- It returns to normal state when temperature rises. No display. ----- Has the Lithium Battery in the main unit worn out? ----- Replace the Lithium Battery with a new one. Incorrect data appear. ----- Execute "All Clear" operation. Current speed does not appear. ----- Is there anything on the contact of the main unit or of the bracket? ----- Wipe the contact clean. ----- Is the distance between sensor and magnet too far? ----- Are the marking line of the sensor and the center of magnet matched each other? ----- Refer to "Sensor/Magnet Mounting" and re-adjust correctly. ----- Is the wire broken? ----- Replace the Bracket & Sensor part with a new one. Transmission signal loss in damp or wet conditions. ----- Water or condensation may collect between the bracket sensor and the computer causing an interruption in the data transmission. Wipe the contacts with dry cloth. Contacts can also be treated with a water repellent silicon jell from an automotive parts or hardware store. Do not use industrial water repellent; it may damage the bracket. When the S/S button is pressed, the unit doesn't activate or stop. ----- Is the unit in the Auto function? ----- The S/S button doesn't function in the Auto function.

MAINTENANCE/PRECAUTIONS

Do not leave the main unit exposed to direct sunlight when the unit is not in use. Do not disassemble the main unit, sensor and magnet. Don't pay too much attention to your computer's functions while riding! Keep your eyes on the road and duly consider to traffic safety. Check relative position of sensor and magnet periodically. For cleaning, use neutral detergent on soft cloth, and wipe off later 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 clogs between the button and the body, the movement of the button may be disturbed. Softly wash away such objects with water.

MOUNTING TO BIKE
The spokes must run correctly through the inside the magnet as in fig.8. Attach the sensor with Sensor Bands-A-B to the right fork. Choose a band that fits the fork diameter (S size for up to 24, L for oversize). 1. Insert the band-B into the slit of the band-A, and put the rubber pad inside of the band-A(fig. 9). Adjust the length in order that the screw-fastening part of the bands are parallel when mounted to the fork(fig. 10). *To pull out the band B from band A, tug strongly. 2. Mount the adjusted bands to the fork along with the sensor, by temporarily tightening the screw(fig. 11). 3. Align the magnet's center and the sensor's marking line(fig. 12), and make sure of 2mm clearance between the magnet and sensor (fig. 13). Then tighten the screw securely. Cut the excess of the band-B with a nipper or the like. Secure the wire with tape as fig. 14. Wind the wire round the outer cable and adjust length. Loosen the wire in the area marked with the arrow so that the wire does not hinder handlebar operation. Use either 1mm- or 2 mm-thick pads if necessary, according to handlebar diameter. Attach the bracket close to the handlebar stem (fig. 15). Slide main unit onto the bracket from front until it clicks into position. To remove, pull it off forward while pushing down the lever. (fig. 16)

MAIN UNIT PREPARATION

The following must be completed before operating. (1) How to measure wheel circumference (L) of your bike (Fig.4)
Put a mark on the tire tread and ride the bike one full wheel revolution. Mark the start and the end of the revolution on the ground and then measure the distance between the two marks. This is your actual circumference. Or, the "Selecting Values Cross Reference Table" tells you an approximate circumference according to tire size.

(2) Setting Speed Scale

Preform all clear operation. All displays will illuminate. Then mile/h alone will be displayed as illustrated in fig.5. Km/h and mile/h are alternately displayed with each press of S/S button. Press M button to set desired speed scale. The display will change as fig. 6.

(3) Setting the wheel circumference (Fig.6)
The standard wheel circumference of 216 cm for 27" wheel is displayed. When using 216 cm without revision, press M button. ODO will be displayed and 216 cm is set. For revision, press S/S button to increase the number by one. To increase rapidly, hold down the button. When the desired number appears, press M button. ODO will be displayed, and the desired number is set.

Test (Fig.16)

Mount main unit. If main display does not show any figures, press either M button or S/S button to release from power saving function. Spin the wheel to check if sensor pulse symbol flashes. If not, adjust relative positions of magnet and sensor following the instructions.
sensor band A sporkes sensor band B
(4) Resetting or changing the wheel circumference
Set main unit in ODO with M button, and stop it with S/S button. Press SET button. The stored number will flicker on the sub-display. Revise the number as desired according to the instructions in (3).

Setting the clock time (Fig.7)
Press M button over 2 seconds to select , and stop it with S/S button. Then press SET button, and minutes flash. Press S/S button to advance minutes by one. To advance rapidly, hold down the button. Set the time one or two minutes ahead of the current time. Then press M button, and hours will flash. Use S/S button the same way. Press SET button to complete time setting. *When you press the SET button, the undisplayed seconds will turn to zero. For accuracy, set by the radio time signal.
