Note: To measure accurate tire size, please refer to the following ways per
instructions.
Lower Line information
Middle Line information
Display the time in 12-hours or
24-hours clock.
CLOCK
Measure the time on riding from the
reset on measured value since last
time. (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
The indication on the present 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.)
(-999~19999)
ALTITUDE
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
Measure the distance on riding since
the reset on measured value 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)
ODOMETER
Measure the amount of
calories consumption from
the reset on measured
value since last
time.(0~19999)
CALORIES
the unit will scroll and change to next
information page automatically per 5
minutes.
Auto Scroll
To indicate the present degree on
temperature. (0~199)
Temperature
The “up” arrow on the screen displays the present speed is higher
than the average speed. On the other hand, the “down” arrow on the
screen displays the present speed is lower than the average speed.
The up symbol above the RPM indicates the current average rate is
higher than average rate of cadence. On the contrary, when the arrow
is facing down, the current average rate is lower than average rate of
cadence.
LCD contrast can be adjusted when the battery is installed on the unit. In the
meantime, all the icons will show up on the display by 3secs, in the meantine, press
function key(darker) or Backlight/Switch key(lighter) any of it to make adjustment .
If the setting is done, press setting Button to exist.
Press function key for 3 secs can clear the present data back to Zero execpt the
altitude adjustment. For the altitude adjustment, please refer to the operation of
Altitude adjustment Mode.
Data Reset
If the main unit does not receive a signal or when keypads or sensor do not triggered
after about 10 minutes, the main unit enters power saving mode and only displays
the time info.
Power Saving Mode
Under the power saving mode, press function key can wake up the information

The product supports ANT + speed and cadence sensor. If we need to re-pair it,
please enter the setting mode. Set the mode to the system in SC.SCAN to perform
the pairing. Since this product supports two bikes recording in A or B , you can select
one of it, and pair the speed and cadence sensor, the system will record the sensor
ID paired in A or B bike respectively, When you choose A or B mode, the system will
imported the related sensor ID automatically.
Speed/Cadence Sensor Pairing
Under the information browsing page, if any of 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. After the setting is done, press the function key
for 3secs again to return to the informatin page.
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 mountain riding. The height can be acquired
on the positions.
2. Home: Adjust and input the altitude manually according to the default altitude at
home.
3. Default: Calculation on altitude according to the factory default.

★ Please make sure the unit has been well-clicked into the bracket.
Installing on Magnet of Speed Sensor
Please remove any dirty or oily things on the spoke to make sure no slipperiness
before installing magnet.
Release the safety hook on the magnet.
Be sure to clip it on the spoke tightly into the most inner side of gap on the central
of two-sided magnet
．
Lock the safety hook back on magnet in order to avoid it being thrown off in cycling.

Installing Cadence Magnet
Please place the cadence magnet into silicone band.
Please penetrate the wider strap into the the silicone band to prevent the cadence
magnet fallen off.
Please measure and circle the silicone band on the crank to measure the most
proper in length and cut the extra unnecessary pars of band off by a scissor.
Finally, fix the position of silicone band by the strap.

(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.
When there is a low-power icon
appearing on the screen, please
replace it with a new battery as soon
as possible.
The battery type for the sensor is
CR1632.
You can advice the bike store for
purchase of CR1632 battery for the
replacement.
For cleanness of the unit or accessories, moisten a soft clothe in and diluted neutral
detergent and wipe it clean and dry with another towel.
