9. Frequently asked questions and troubleshooting
1. I was updating my Altis Micro and it does not function anymore. It was OK before.
Probably the process of firmware upgrade was not done in the right way. Connect your Altis
Micro to the computer and wait. The new firmware should be upgrading. It is indicated by
flashing with increasing pulse length. Within 30 – 150 seconds it should appear on the PC as
a disk drive. In some cases backup firmware can be activated. The backup firmware is
indicated by combination of short and long flashes ( . - . - . - . - . - . - ). 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. I 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 1200μs.
4. When I fly with Altis Micro and stop the motor, it is not stopped and propeller continues spinning
slowly. When I fly without Altis Micro, the motor break runs correctly.
Try to set fixed endpoints on your ESC.
5. In case AFM can not read the flights from the device or Altis micro does not behave according to
the settings, the file system might be corrupted. The reason might be disconnection in a wrong
time or not ejecting in Windows.
In order to fix this error, format the file system by clicking the Format device button in Device
Window and restarting the device. Or this can be achieved also by renaming Altis micro disk
from AE_DISK to AE_DISK1 in
My Computer
folder and restarting the device.
6. I want to allow Emergency Motor On, but (occasionally) it does not work, though all the settings
are correct.
The motor off throttle in value might not be present during all the initialization time. In such
case default value 1000μs is used. The problem appears if your motor off value is above
1000μs, so the motor off is not detected and motor is considered active.
Extend end the low end point bellow 1000μs. Motor off will be detected correctly also when
the motor off value during initialization is not correct.
