Stabling Pads
Cadence Sensor
Mount the sensor on top of the left chain stay with
long nylon ties, make sure the cadence side face the
front and speed side face the back. The distance
between the sensor and the cycle computer would
approximately be 150 cm.

2.4 How to mount the magnet
Secure the Cadence Magnet on the inner side of crank and
make sure the magnet side faces the cadence sensor zone.
The maximum distance between the cadence sensor and
the magnet on the crank is 5 mm. Once above items are in
the right position, the user may go for a ride.
Note: Initial ashing green light indicates the sensor
detected magnet signals normally. Please make sure
everything has been setup correctly before riding
the bicycle.
Secure the Speed Magnet on the spoke of the back wheel with screw. Make
sure the magnet side faces the speed sensor zone. The maximum distance
between the speed sensor and the magnet on the spoke is 5 mm.

2.5 Find out the wheel size
Wheel Circumference
To get the accurate result, the wheel size should be correct. Mark the
symbol on the tire and ride one circle. Then measure the length between
two points to get the circumference. Or the user can also get wheel
circumference by the following equation:
Circumference (mm) = 2 x 3.14 x R (inch) x 2.54 (1 inch = 2.54 cm)
R=Radius in centimeter
The user can refer the “wheel size chart”
on page 21 for the wheel size

5.1 ID SCAN MODE (Pair up)
5.2 CLK MODE (Clock Mode)
How to pair up the cycle computer with speed/cadence sensor
How to set the Time
Under any mode, press and hold “Set & Mode” keys for 3 seconds to go
ID scan. Kindly place the sensor at maximum allowable distance within 150
cm to the cycle computer. It will pair up the cycle computer to the speed/
cadence sensor automatically. When the percentage shows 100% means scan
completed. ID scan is failed if “Err” sign shows after scan completed. The user
can press “Set” key again to scan again, or hold “Mode” key to exit ID Scan
mode. ID scan will automatically exit after 30 seconds.
Press and hold “SET” key for 3 seconds to set
clock.
Press “SET” key once to adjust 12/24 hours.
The timer will be in COUNT UP if setting is 0:00:00, otherwise it will be
in COUNT DOWN. The TM+ will repeat with ashing digits if it reaches
up to 9:59:59. The TM- will also repeat with ashing digits when the
time set has run out.
Press “MODE” key to
adjust time (hour, minute
and second).
Press “SET” key to adjust timer count down or count up (hour and minute).
Hold “MODE” key for 3 seconds to go back to Clock Mode once the setting is
nished.

5.3 TM - or TM + MODE (Timer Count Down or Up)
5.4 T. TM MODE (Trip Time Mode)
Timer Count Down and Count Up will depend on users’ prior setting in Clock
Mode.
Trip Timer would operate automatically when the bike is in motion.
The timer will be in COUNT UP if setting is 0:00:00, or it will be in COUNT DOWN.
The TM+ will repeat with ashing digits if it reaches up to 9:59:59. The TM- will also
repeat with ashing digits when the time set has run out.
How to reset all data
Press and hold “SET” key for 3 seconds, all exercises results in displayer will return
to zero, except odometer.

The trip distance accumulated from the beginning onwards.
Note. If the time or distance is over the max value (29 hr: 59 min: 59 sec or Distance:
999.99km), It will not be able to measure correct average speed by showing “Err” on the
displayer. Once the time & distance value has been reset, the average speed will show
normally.

5.8 ODO (Total Odometer Mode)
How to change speed scale and wheel settings
• Under ODO Mode, press “SET” key for 3 seconds to go to
setting.
• Press “SET” key again to select Km/H or Mile/H, press
“MODE” key to go to Wheel Settings.
• Input the correct wheel size by pressing “SET” key, the range
of wheel size from 100mm to 2,999mm.
• Hold “MODE” key for 3 seconds to go back to ODO Mode.
(Refer to Wheel Size Chart)
Note: CY-517C will keep the value of ODO (Total Odometer)
in the memory even after the user changes new battery. The
ODO value cannot be erased by the clear function unless
apply default setting.

5.11 DEFAULT SETTINGS
Under the SCAN MODE, the display will automatically show all modes in
circulating loop every 4 seconds, once the speed has been detected. Press any
key to stop SCAN feature.
The Default Settings will clear all the measured value except ID CODES. Under
any “Setting modes” (Clock setting, Odo setting or Calorie setting), press and
hold all “MODE” & “SET” keys at the same time for 6 sec until all the values
return to default values.
The default setting will keep the ID Code after all the default values.

Maintenance
Chapter 6
CY-517C cycle computer
If the display contrast changes and gures become faint, it’s time to replace the
battery. Consider changing the computer sensor and transmitter batteries at the
same time.
Note:
Do not expose CY-517C computer to extremely cold or hot temperatures i.e. don’t leave the
unit in direct sunlight for extended periods of time.
Sensor
Check the position of sensor and magnet periodically. For current measurement,
the sensor, magnet should not get wet/ rust, otherwise it may cause function
error.
Bracket / Magnet / Sensor band
These items can be rinsed in surface fresh water or washed with a mild soap.

Troubleshooting
Chapter 8
Q1. Display is black or very light:
The battery power may be low. Try a new battery to make sure the battery is
installed correctly.
Q2. Display becomes dark or black:
The unit is too hot. Place the unit in a shaded area, and it will return to normal.
Q3. The unit operates slowly or struggled:
The unit is too cold. Warm the unit, and it will return to normal.
Q4. Date in display varies enormously:
Check your surroundings for electro magnetic or high energy interference and
move away from the source of interference.
Q5. Data in display shows slowly:
The unit may be affected by low temperature factor but it didn’t inuence the
function reading. When the temperature rises, the data reading/ witch will back
to the normal.
Q6. Current speed does not appear
It may be caused by the following situation: the distance & position between
magnet and sensor to adjust or low battery power.
