• Before each update, check the transmitter battery charge or
charge it as a precaution, and save all model memories so that
they can be restored if necessary.
• Do not disconnect the link to the computer during an update!
Make sure that the link between the transmitter and computer
is operational.
• After each update, check to make sure that the models function
correctly.

unpack it on your computer. Insert the supplied mini SD Card in the
card slot of your PC and copy the required firmware file from the
unpacked software package into the directory “Firmware“ on the

insert it in the card slot of the transmitter. Switch on the transmitter
and the RF module off.
Go to the submenu “FIRMWARE UPDATE” in the menu “Hidden
