bracket is secure. (Fig. A)
2. Slide the main unit onto the bracket from front to rear until it clicks into position.
To remove the main unit, press down on the bracket locking lever then push the
main unit forward and off. (Fig. B)
1. Attach the sensor to the sensor band with the screw .
Mount the band carrier onto sensor band. (Fig. C)
2. Mount the sensor unit on the right front fork with rubber pad. (Fig. D)
3. Mount the magnet on one spoke of the front wheel, The magnet should face the
sensor's mark line . Place the ring around the magnet to enhance the
reliability of the set screw. (Fig. E)
4. Adjust the relative position between the main unit and the sensor, according to the
following key points:
a. Adjust the magnet fixed position until the center of the magnet is aligned with
the line marked on the sensor. (Fig. E)
b. Adjust the sensor to set the gap between the magnet and the line marked on the
sensor at about 5mm (0.2"). (Fig. F)
c. Adjust the angle of the sensor to aim in the direction of the main unit +/- 15 .
The best performance is acheived with the sensor arrow oriented perpendicular
(90 ) to the battery cap of the main unit. (Fig. G)
1. The main unit has a " On/Off Detecting Switch " (patents pending) to turn ON/OFF
the power of the wireless receiver. It can receive the wireless wheel signals only after
the main unit is installed onto the bracket.
2. Spin the front wheel to check if installation is correct. Correct installation is
confirmed if the main unit blinks the " " symbol. The installation is incorrect if " "
is not displayed. Please check the relative position of the main unit, the sensor and
the magnet, or refer to the trouble-shooting table.
1. The sensor transmits the rotating wheel signal to the receiver in the main unit by
wireless transmission. To protect the receiver from interference from other wireless
noises - causing the main unit to display false data, install the transmitter
according to the following key points to improve performance.
a. The receiver is designed to receive a signal from only a certain direction and
angle to reduce the noise interference from other sources. Adjust the installation
angle of transmitter to aim in the direction of the main unit within a +/- 15 , The
best performance is with a vertical orientation.
b. The receiver will receive a stronger wireless signal if the transmitter is closer to
the receiver. A stronger sensing signal not only has better noise immunity, but
also increases the transmitter battery's operating life. For good wireless
performance, please install the transmitter as close to the main unit as possible
and within 45 cm (1.5 feet).
2. Precautions
a. This computer experiences almost no cross-talking interference when 2 bicycles
carrying the same or similar wireless cycle computers are ridden side by side, as
long as the cross-distance is over 40cm (15.8").
b. This computer has excellent noise immunity to some forms of electromagnetic
interference, but it may be effected by strong electromagnetic waves which will
cause the main unit to display erroneous data while it is near the source of strong
interference; such as TV transmission stations, radar stations, and some heavy
industrial machines.
3. This computer has a "On/Off Detecting Switch" to check that the main unit is
installed on the bracket.
a. To reduce the power consumption of the main unit and to increase the battery
operation life, but also to protect against all indoor electromagnetic interference
from electrical equipment (such as PC monitors, mobile-phones, etc.). It will turn
off the power supply of the receiver when the main unit is removed from the
bracket.
b. The main unit can only receive the wheel signals after it is installed onto the
bracket.
a. The symbol " " will appear to indicate the battery is nearly exhausted.
b. Replace the battery with a new battery within a few days after the symbol was
appeared.
c. All data will be cleared when battery is replaced, but this computer allows you to
re-key in ODO which you have ridden after replacing battery, record this data
before you remove the old battery.
d. Replace with a new CR2032 battery (Fig. K) and initiate the main unit.
a. The patent-pending transmitter circuit is designed to reduce power consumption;
a 1.5V battery (typically an LR44) can operate for over 24.000km (15.000miles)
riding distance or 2 years.
b. Replace a new battery when the transmitter's battery power is nearly exhausted,
otherwise the transmission power of the wheel signal will be weak, causing the
main unit to display unstable data.
c. Replace with a new LR44 battery with the positive (+) pole toward the sensor
cap . (Fig. L)
