(00:00~99:99)
MOVE TIME
Measure average speed calculated from
the total distance divided with time on
riding. (0~9999.9)
AVG . SPEED
Measure the fastest speed from the
reset on measured value since last time.
(0~9999.9)
MAX SPEED
Measure the highest altitude from the
latest reset on measured value.
(0~19999)
Max. Altitude
Measure the grand total of ascent
altitude from the latest reset on
measured value. (0~19999)
Total Altitude
Indication on the present value of grade.
Grade is calculated by the variation on
the distance and height because the
calculation based on the barometer will
result in discrepancy and be slightly
inaccurate.
GRADE%
Measure the distance on riding from
the reset on measured value since last
time.(0~9999.99)
DISTANCE
When resetting the odometer, the data
won’t return to zero, you need to
change the value of it in the setting
mode.(0~9999.99)

Spin the wheel and choose one piece of the
spoke or let the valve stem vertically straight
to the ground to be A point marked on the
surface of ground.
Then spin the wheel in one circle and when
the same piece of spoke or the valve stem
reach to the ground again, mark the position
of it as B point on the ground.
Measure the distance between point A and B
(mm) to acquire the wheel size for setting.

Press the button to switch and look through the cycling information on information
page.
In the setting mode, press the button to change numbers or measurement units.

bike in advance; the system will store and input the sensor ID of A or B Bike automatically next
time. (Please swing the magnet over the detection zone on the sensor to activate the sensor
before performing the pairng with computer.)
Pairing the Speed Sensor with Unit
Under the information browsing page, if any of the it contains the altitude related info(like
MAX.ALT, TOT ALT, GRADE), in the meantime, press function key 1 for about 3 secs to enter the
altitude adjustment mode.
There are three selections for altitude adjustment.
1. ADJUST: Adjust and input the altitude manually according to any operating environment like
riding along seacoast or up to the mountain and the height can be acquired on the positions.
2. Home: Adjust and input the altitude manually according to the default altitude on your
home.
3. Default: Calculation on altitude according to the factory default.

Notice !
No Display:
(1) Check the battery capacities and it will be in low efficiency when in the cold season.
(2) If the battery installed upside down?
(3) Make sure the battery case locked on the unit.
No Speed info:
(1) Check if there are some dust inside the contacts on bracket or on the unit.
(2) Make sure the distances between sensors and magnet is within 5mm.
Not Correct Value on Speed and Distance:
(1) Make sure the correct value setting on tire peripheral.
(2) Make sure the distances between sensors and magnet is within 5mm.
(3) Unload the battery and install again.
The screen becomes dark: Check if there is high temperature in environment.
The screen becomes dim: Check if the power of battery is low.
System Delay:
(1) Check if there is over low temperature in environment.
(2) Check if the power of battery is low.
The inaccuracy on the altitude:
The present altitude is calculated based on the barometer, even at the same position, the altitude
may have a little discrepancy due to the different conditions on the weather. Even when in a
stable weather condition, the same position of altitude may differ in 20 meters from daytime to
nighttime The longer you are using the computer may lead to larger discrepancy. We suggest to
manually input the present altitude when inaccuracy.
Do not concentrate on the computer operations while bicycling. Always be sure to
bicycling safety.
Please check the distance between magnet and sensor within 5mm periodically.
Never disassemble the main unit.
Do not leave the main unit directly exposed to sunlight.
Periodical check the positions on the magnet, sensors and bracket.
WBC-302 only supports in ANT+ speed sensors. It doest not support ANT+cadence sensors
or two-in-one sensors, heart rate sensors or other ANT+ accessories.
