## mode: • Powerthe transmitter and

**Chroma'~** quadcopteron and face the aircraft pointing North. • Cycle the top lefttransmitter switch completely 4times 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 ortwo 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 quadcopteras shown in the illustration below within 30 seconds. •Afterthe last rotation step, hold the quad level, facing North and checkthe LEOs.

Accelerometer Calibration Procedure* • Poweron the transmitter and Chroma quadcopter. • Place the quadcopteron 

### aflat, level surface. •While holding the bind switch on the transmitter, cycle the top left switch 

### 4times as shown at the right. •The Chroma quadcopterwill emit aseries of slowtones followed by

### aseries 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.comfor 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. 

### Bindingthe Chroma QuadcopterTo YourTransmitter 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. Powerthe 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 backypright. -··· 

### --- - ··---· 

# - 5. On yourtransmitter, ensure the throttle is in the low position and the

throttle trim is at neutral. 7. Power ON yourtransmitter in bind mode according to the instructions

**~-ed** with yourtransmitter.

**·---------·-~-** 

### a_ When the binding process is successful, the quadcopter will emit aquick,

3-beep tone and the LEOs will indicate which flight mode is selected. Ifthe LEOs are flashing red, the quadcopter is in Return Home mode. Switch to Smart orAP Mode_before attempting to

**sta~**the motors. 9. Place the quadcopter outdoors in the desired starting position

in preparation for flight. 

## Troubleshooting Quick Reference Problem Solution Motors won't start Blinking yellow led 'compass error' indication Steady beeping, motors won't start Won't hold position in hover Ensure GPS antenna has clearview of sky and GPS lock has been acquired Check for compass error indicat!?"---· Review start up procedure in manual Move model away from large metal objects or surfaces Calibrate compass
