You are receiving red Xs means there is a short and a call to Dynon.

There has been issues of the EGTs spiking when pressing the PTT and that was resolved with a updated/replaced EMS unit.

Akash -
What aircraft hull material type ?
Where is you Com antenna located in relation to the EMS unit ?
What type of antenna coax cable are you using ?

note - if you are using a recently purchased EMS unit then the 'issue' would normally be elsewhere, answers to the questions may be very helpful.
