Gemini Rabbit VC2000 & VC2100

[Indian Head]

Hi

In order to get some proper programming on our old tv sets, we purchased a Gemini Rabbit transmitter (VC2000) and receiver (VC2100). It came without a manual. It does work as we can send video and audio from the unit to a TV set at a remote location. However, in order to optimize the operation, I'd like to get the manual. There are two little trim pots on the transmitter next to the inputs and I have no idea what they do.

Can anyone let me know where we could find a manual for these units?

Thanks!
