Hi all, coming back after almost 10 yrs. Recently I took out my RC cars for kids. I have two 3PM 2.4 transmitters and 3 receivers (2 x r603ff and 1 x r603fs)

Problem arose when I linked one of the transmitters to a receiver which was already linked to the second transmitter.

Now if I am running two cars at the same time, as soon as one of the transmitters is turned off, the second one takes over and starts controlling both the cars..

Also noticed that once linked, it does not link back to the first transmitter when it's turned on.

I have googled and searched but only found instructions to link receivers and transmitters but not to unlink them..

There is mention of resetting model memory on the TX, however manuals are showing that transmitter ID is stored in the receiver. Is there any way to clear receiver memory?
