Subject: C-408  Expanded RF Rx/Tx

Procedere:
1. The fan from the black box shows to you
2. Open the 4 screws of the black box and remove the cover
3. Locate the main processor. It is between the microphone and the external speaker connector  

4. Behind the processor there are 7 solder pads  
5. The left 3 are diodes and have nothing to do with this, then there are 2 empty ones and 2 with 0 Ohm resistors.
   
(Check this before you go further)

6. Remove these resistors
7. Make a full reset (pressing 0/func while switching on, then setting Reset-mode to AL with 2/down or 3/up then resetting it with c/sql)

RX/TX then is depending on the US/EU version

You should be aware, that you do every mod on your own risk and I am responsible for nothing.
