Questions & Answers

We've just purchased an E&H Promag P and are having problems setting new parameters. Seems the Esc buttons + & - and the E don't have actual pushbuttons. Holes are there but I don't believe they're pushbuttons. How do I get into this unit to set up? (1 answer)

Hi Don, it is optical touch control button. They does look differently than the pushbuttons but they work perfectly. Otherwise Transmitter 300 has RJ45 Interface and can be configured over Browser as well. Da/Visaya
