Turn the quadcopter to point the orange LEDs North, then rotate the quadcopter 360° as shown by the blue arrowsbelow. Complete all 4 rotations of the Chroma quadcopter as shown in the illustration below within 30 seconds.tAfter the last rotation step, hold the quad level, facing North and check the LEDs.Green = ReadyRed = Repeat Compass CalibrationtPower on the transmitter and Chroma quadcopter.tPlace the quadcopter on a fl at, level surface.tWhile holding the bind switch on the transmitter, cycle the top left switch 4 times as shown at the right.tThe Chroma quadcopter will emit a series of slow tones followed by a series of rapid tones, indicating the calibration has started.tDo not move the quadcopter while it performs the accelerometer calibration procedure.tWhen the procedure has completed, the quadcopter will emit a “happy” tone and the LED will display green indicating thecalibration was successful. If it emits a “sad” tone and the LED displays solid red, repeat the calibration procedure.See the online videos atwww.KnowChroma.comfor complete calibration procedures.4X4XabcdCompass Calibration Procedure*Accelerometer Calibration Procedure*Troubleshooting Quick ReferenceFor a complete description of the function, capabilities and maintenanceof the Chroma quadcopter, refer to the online videos atwww.KnowChroma.com.Problem SolutionMotors won’t startEnsure GPS antenna has clear view of skyand GPS lock has been acquiredCheck for compass error indicationReview start up procedure in manualBlinking yellow led‘compass error’ indicationMove model away from large metalobjects or surfacesCalibrate compass(see calibration reference)Steady beeping,motors won’t startCalibrate the DX4 transmitterCenter throttle trim (BNF version)Won’t hold position in hoverCheck GPS antenna mast is extendedCalibrate compass(see calibration guide)Calibrate accelerometers(see calibration guide)BindingBinding the Chroma Quadcopter To Your Transmitter1. With the transmitter and quadcopter powered OFF, connect the battery tothe quadcopter.2. Place the quadcopter on a fl at level surface.3. Power the quadcopter ON and let it initialize. The status LEDs will remain off.4. Hold the quadcopter upside down until the status LEDs fl ash blue, indicating it has entered bind mode.5. Set the quadcopter back upright.6. On your transmitter, ensure the throttle is in the low position and thethrottle trim is at neutral.7. Power ON your transmitter in bind mode according to the instructionsincluded with your transmitter.8. When the binding process is successful, the quadcopter will emit a quick,3-beep tone and the LEDs will indicate which fl ight mode is selected.If the LEDs are fl ashing red, the quadcopter is in Return Home mode.Switch to Smart or AP Mode before attempting to start the motors.9. Place the quadcopter outdoors in the desired starting positionin preparation for fl ight.For instructions on binding with GPS disabled, refer to the online videoatwww.KnowChroma.com.* For information on calibrating the Chroma quadcopter with the ST-10+ Ground Station transmitter, see the online video atwww.KnowChroma.com.North
