each series has different models, each model has different LED indicators. You may find
that the photo has a set of LED indicators different from your computer, the photo is for
reference only.
Different series with different needle tachometer or speedometer scales are as bellows:
CA-085-15X: 150Km/H
CA-085-21X: 210Km/H
CA-085-26X: 260Km/H
The last suffix “–XX can be identified material of the upper bezel as bellows:
No. suffix: Plastic material.
-AB: CNC aluminum bezel with anodizing mesh black treatment.

1. Connect either the yellow or white wire to sense the RPM signal.
2. The yellow wire can be wrapped around the spark plug lead.
a. Signal strength from the ignition coil is dependent on coil type.
b. Coil 2-5 turns around spark plug lead, the more turns the stronger the
signal. A weak signal will not show a reading on the screen whereas a
very strong signal will have a reading which is too high or very jittery. If the
reading is incorrect then try putting the 1MΩresistor which is included in the
box inline in the sensor wire.
3. If the signal is still unstable, please try to connect the white wire to either the
ECU rev counter output or to the primary side of the coil or to the pulse wire on
an active spark plug cap.

1. This sensor is universal sensor for motorcycle, find a rotating part to install
magnet (for example disk, sprocket or driveshaft) and a location to install the
sensor where it can be aligned to the magnet.
2. Align the center of the magnet to either of the sensor marking lines or the
side of the sensor. The magnet must not travel down the body of the sensor
3. Installing the sensor parallel to the vibration direction creates optional
anti-vibration effect.
4. Make sure the gap between the magnet and the sensor is within 8mm.
1. ODO accumulates total distance traveled.
2. ODO data is adjustable when it is less than 30km (18.6 Miles), after that it stored
in memory and cannot be reset.

*MAX TEMP: Maximum Temperature
Displays highest temperature achieved since last Reset operation.
: Digital Voltage and Battery Warnings
Specific Hall sensors:
Cable drive adaptors for most bikes originally fitted with cable driven
speedometers or odometers are available. When using these cables it
is necessary to divide the circumference setting by the number of
rotations of the cable per rotation of the wheel.
*Thermo Sensor and Sensor Tube:
1. The unit includes a water temperature sensor; you may have to
purchase a suitable water pipe temperature sensor tube to install
the sensor on some bikes.
2. Cut the water pipe, insert the temperature tube into the pipe and
secure it by attached pipe clamps.
3. Screw the sensor into the tube.
4. If your vehicle is fitted with a thermostat that stops water flowing to
the radiator when the engine is cold, you will not get a reading until
the thermostat opens.
5. Custom sensors are available for carburetted bikes to replace the
original sensor.
1. It checks bike’s battery and charging systems health.
2. Indicates range 8-18VDC.
+TRIP: Maintenance Reminder
1. The maintenance reminder is set by trip meter, and an “Off” mode to switch it off.
2. The trip meter maintenance can be set up to 9999km.
