Installing the Cadence Magnet
Put the Cadence Magnet on the Crank and
must face Cadence Sensor
Note: The max distance between the Cadence
sensor and Magnet should be within 5mm.
Installing the Cadence & Speed Sensor
Check the right side of the Chain Stay to
nd the suitable point to attach the Cadence
& speed sensor. The distance between
cycle computer & the sensor would be
within 150 cm.
Installing the Speed Magnet
Put the Speed Magnet on the left spokes
of the back wheel and must face the speed
sensor.
Note: Turn the speed handle to adjust speed sensor. The Max distance between speed sensor and
Magnet should be within 1mm~5mm.

Please check green light on the Cadence
& Speed sensor to make Bitmap sure 2
functions operated normally when riding your
bicycle at rst time.
Note: Please turn around the wheel to check
the green light on the sensor, Initial ashing

5.2.1 ACTUAL ALTITUDE
Because air pressure will inuenced by temperature or
weather changes while goes out for a ride. In order to
correct the inuence of the weather change or temperature
changes, the user can also adjust the actual altitude on CY533AC. If the user sees a road sign indicating actual altitude
that is differ from the actual attitude value on the device, the
user may adjust actual altitude according to the sign.
Under ACT. ALTI
• Press A key or C key to adjust actual alatitude.
• Press M to transfer next setting.
5.2.2 HOME ALTITUDE
The “home altitude” is the altitude of the starting location
(home or starting point). This value can be found by maps,
internet or newspaper. Once the number is entered into
CY-533AC. It will calculate automatically. The accurate
calculation of altitude requires the precise information for
home altitude. To make CY-533AC indicating altitude and
climbing more precisely, home altitude must be set up in
advance.
• Press A key or C key to home altitude.
• Press M to transfer next setting.

5.2.3 RE-CALIBRATING THE ALTIMETER
Due to change in local barometric pressure inuenced by temperature and wind,
the user may notice the ending altitude is different from the home altitude as day
goes by. It is normal because of pressure inuences over time. So before goes
out for a ride, we suggest to call back the home altitude value in CY-533AC.
Any Mode
A & C > 2 sec
• Under any mode, press and hold A key and C key at same time for 3 sec until
“SET HOME” display.
• The user can call back the value for home altitude you have entered before at any
time.

The advange of 2.4Ghz wireless transmitting technology is stablized signals
from the chest belt or speed sensor to the cycle computer. CY533AC can avoid
noise interference from other devices while it is working with speed sensor.
Each device and sensor has been ID SCAN after manufacturing.
So the user can start to use the product immediately without doing ID SCAN.
The main purpose of ID SCAN is to pair up the cycle computer to its speed/
cadence sensor as well as to prevent signals and cross talk from other cycle
computers. Each cycle computer set has been pre-ID Scan right after it’s
produced, so the users do not necessarily need to run ID-SCAN after their
purchase. The users would need to run ID-SCAN as if additional speed/cadence
sensor are being replaced or for purpose of second bike uses.
NOTE
The BIKE1&BIKE2 can coordinate with one individual code from one speed sensor or two
individual codes with additional speed sensor, chest belt respectively.
Under any mode, press A key and C key at same time for 6 sceonds.
When the percentage of shows 100% means scan completed.
(Please note that speed sensor have to be in wake up mode)

TroubleshootingSpecications
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 inuence 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.
