In this case run the firmware upgrade again If the firmware upgrade was finished successfully your Altis Micro should run in a USB mode indicated by long flashes Please follow the instruction on the screen during update 2 see the height on the graph increasing to several meters during a test on the ground Is my Altis Micro broken No The barometric pressure depends on the weather Sometimes it can change variations of several meters in the measured height Other cause can be a heated Altis Micro Do not put Altis Micro near hot objects in your fuselage 3 My Altis Micro measures F5J height even if do not start the motor After power on the F5J height is discarded This might be caused by too high zero throttle level In such case Altis Micro considers the signal to correspond to switched on motor Please check the zero throttle level in your radio system It must be set bellow 1200us 4 When fly with Altis Micro and stop the motor it is not stopped and propeller continues spinning slowly When fly without Altis Micro the motor break runs correctly Try to set fixed endpoints on your ESC 10 Correct disposal of this product This product should not be disposed with other household wastes at the end of its working life To prevent possible harm to the environment or human health from uncontrolled waste disposal please separate this from other types of wastes and recycle it responsibly to2.
