• Power the transmitter and Chroma'~ quadcopter on and face the aircraft pointing North. 

• Cycle the top left transmitter switch completely 4 times as shown at the right. 

• The quadcopter indicates it has entered compass calibration mode by flast1ing the LEOs orange. 

• The LEOs will indicate which direction to orient the quadcopter for each rotation by lighting either one or two motor pods 

orange. Turn the quadcopter to point the orange LEOs North, then rotate the quadcopter 360° as shown by the blue arrows 

below. Complete au 4 rotations of the Chroma quadcopter as shown in the illustration below within 30 seconds. 

• After the last rotation step, hold the quad level, facing North and check the LEOs.

Accelerometer Calibration Procedure* 

• Power on the transmitter and Chroma quadcopter. 

• Place the quadcopter on a flat, level surface. 

• While holding the bind switch on the transmitter, cycle the top left switch 4 times as shown at the right. 

• The Chroma quadcopter will emit a series of slow tones followed by a series of rapid tones, indicating the calibration has started. 

• Do not move the quadcopter while it performs the accelerometer calibration procedure. 

• When the procedure has completed, the quadcopter Will emit a "happy" tone and the LED will display green indicating tile 

calibration was successful. If it emits a "sad" tone and the LED displays solid rod, repent the calibration procedure. 

See the online videos at www.KnowChroma.com for complete calibration procedures. 

*For information on calibrating the Chroma quadcopter with the ST-1 0+ Ground Statton transmitter, see the online video at www.KnowChroma.com. 

Binding 

For instructions on binding with GPS disabled, refer to the online video 

at www.KnowChroma.com. 

Binding the Chroma Quadcopter To Your Transmitter 

1. With the transmitter and quadcopter powered OFF, connect the battery to 

the quadcopt_er. ~--- -~--

2. Place the quad~?.pter on a !_lat level surface. - - 3. Power the quadcopter ON and .. let it initialize. The _status LED_s wi!_~ remain off. 

4. Hold the quadcopter upside down until the status LEOs flash blue, indicating it has entered bind mod~. -·--

!l· Set the quadcopter back ypright. -··· ---- ··---· - 5. On your transmitter, ensure the throttle is in the low position and the 

throttle trim is at neutral. 

7. Power ON your transmitter in bind mode according to the instructions 

~-ed with your transmitter. ·---------·-~-

a_ When the binding process is successful, the quadcopter will emit a quick, 

3-beep tone and the LEOs will indicate which flight mode is selected. 

If the LEOs are flashing red, the quadcopter is in Return Home mode. 

Switch to Smart or AP Mode_before attempting to sta~ the motors. 

9. Place the quadcopter outdoors in the desired starting position 

in preparation for flight.
