SECURING THE SENSOR CABLE (Fig. G)
INSTALLING THE MAIN UNIT (Fig. F)
PRECAUTIONS
1. Mount the SENSOR with 2 cable ties on the front fork with the
RUBBER PAD , and let the sensor face the spoke, do not tighten the
cable ties before the sensor is placed in the right position. (Fig. A)
2. Mount the MAGNET on one spoke of the front wheel and let the magnet
face the sensing zones . Place the RING around the nut to enhance
the reliability of the fixed screw. (Fig. B)
(New magnet with cross gap fit to all wheel spokes both aero and round).
3. Adjust the relative position between the sensor and the magnet. (Fig. C)
a. Align the center of the MAGNET to either of the sensing zones .
b. Make sure the GAP between the magnet and the sensor is within
4mm (1/6 inch). Adjust the desired gap by moving both the magnet
and the sensor up or down.
IMPORTANT: If either a) or b) is incorrect, poor signal input will result.
4. Be sure all relative positions are correct, tightening the cable ties so they
will not move.
5. Cut the excess strapping on the cable ties when the installation is finished.
(Fig. D)
1. Two rubber shims are included to attach the mounting bracket to your
handlebar securely. The thinner shim is to be used with large diameter
handlebars up to 31.8 mm . The thicker shim is to be used with 25.4 mm
or greater diameter bars. Both shims can be used for bars less than
25.4 mm .
2. To secure the bracket to the handlebar, place the mounting bracket in the
correct position, run cable ties through the passages in the bracket, wrap
around the bar and fit pad(s), insert into the cable tie closure, and pull tight.
Do not tighten cable ties before the bracket is in the proper position.
3. CAUTION! When trimming the cable ties, be sure not to leave any sharp
rough ends which could result in injury.
1. Select suitable positions to secure the sensor cable to the fork with CABLE
TIES.
2. Make sure the sensor cable is loose enough for the handlebar to turn
freely before tightening the cable ties.
3. Secure excess wire near the fork crown by wrapping it around the front
brake cable or by bending it back and forth and securing it with cable ties.
1. Mount the main unit onto the bracket by sliding it from front to rear until it
clicks into position.
2. This bracket is designed with a locking lever to secure the main unit and
prevent it from coming loose during use.
3. To remove the main unit, press down on the lock lever, then pull the main
unit forward and off.
1. When the brightness of the LCD display begins to dim, this
indicates that the battery is nearly exhausted.
2. Replace with a new LR44 (Cross reference type A76, AG13 or
V13GA) battery in the compartment on the back of the computer
with the positive (+) pole toward the battery cap. (Fig. H)
1. This computer can be used in the rain but should not be used under water.
2. Don't leave the main unit exposed to direct sunlight when not riding the
bike.
3. Don't disassemble the main unit or it's accessories.
4. Check relative position and gap of sensor and magnet periodically.
5. Clean the contacts of the bracket and the bottom of the main unit
periodically.
6. Don't use thinner, alcohol or benzine to clean the main unit or its
accessories when they become dirty.
7. Remember to pay attention to the road while riding.
Check the following before taking unit in for repairs.
