Download the actual software package from the Internet, and
unpack it on your computer. Connect your switched off transmitter
with your PC, by using the included USB cable, which is supplied with
the package content, plug USB cable directly to the micro USB port
of the transmitter and the other end to a free port in your computer.
All other information can be found in the instructions that come in
the software package.
POWER switch without function
If a firmware update for the transmitter is unsuccessful or the trans-
mitter program freezes and the transmitter cannot be turned off
using the "POWER" switch, then remove the transmitter's battery
after setting the switch to "POWER = OFF" position, or pull the plug
from the transmitter battery, reconnect it after few seconds and
leave the transmitter switched OFF.
Download the most recent update file from the Internet and save
the file in the "RECOVERY" folder in your SD card.
Then change the file name in "R280.bin".
Insert the SD card in the transmitter.
Push and hold the Ctl 5 and Ctl 6 buttons at the same time to the top
and push the Power button.
Now pull the Ctl 5 and Ctl 6 buttons within 2 - 3 sec. to you and keep
them in that position for about 10 sec.
Wait at least 30 sec. On the display there will be no image. During
the update the transmitter cannot be switched on.
After 30 sec. switch the transmitter on.
