Note: To measure accurate tire size, please refer to the following ways per
instructions.
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” arrow on the screen displays the present heart rate
is higher than the average one. On the other hand, the “down” arrow on
the screen displays the present heart rate is lower than the average one.
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.

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.
*Before performing the paring of speed/cadence sensor, please make sure the battery
has been installed and be sure to roll the magnet over the detection zone on the
sensor in advance in order to activate it successfully.
Speed/Cadence Sensor Pairing
To enable the heart rate sensor, please switch to the information page, press the
backlight/heart rate/switch key to enable or disable the heart rate sensor. (When there
is the icon “ ” shown on the screen means the sensor is on, if the icon “ ”
disappeared means the sensor is turned off.
If the unit cannot detect the value of heart rate for 1 min, it will close down the heart
rate function.
Enable the Heart Rate Sensor
The product supports ANT + heart rate sensor.
Please enter the setting mode. Set the mode in HR.SCAN to perform
the pairing process. Please make sure the battery has been installed in the sensor
and wearing on the right position before starting up the pairing progress.
Pairing the Heart Rate Sensor with Unit
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.

*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.
Pair the sensor failed
(1) Check if the sensor is in low power status.
(2) Check if it is connected and paired successfully with the computer.
(3) Check if the speed/cadence sensor is on the correct positon.
(4) Check if the heart rate sensor is on the correct positon.
(5) Check whether the heart rate function is enabled on the computer.
When there is a low-power icon
appearing on the screen, please
replace it with a new battery as soon
as possible.
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.

The heart rate zone is calculated automatically by
the age set on the computer. (We recommend
that the proper status is to keep in zone 2 to 3
when cycling)
EX: If your age is 30.
HR ≧220 - age = 190 BPM
HR ≧190 x 0.9 = 171 BPM
HR ≧190 x 0.8 = 152 BPM
HR ≧190 x 0.7 = 133 BPM
HR ≧190 x 0.6 = 114 BPM
