Garmin SL40 User Settings for System Functions

Piper J3

Well Known Member
I have standard issue Garmin SL40 comm and FlightCom 403 intercom in my RV-12. I?m trying to sort out a static noise problem and have been asking for assistance over in the VAF Avionics Forum - the guys are super helpful.

What I?m asking for here is if anyone has documented their Garmin SL40 user settings for the following System Functions:

? Headphone Level
? Mic Squelch 1 and 2
? Transmit Mic
? Intercom Level
? Sidetone Level

Any help is appreciated?
 
i will be be at my plane tomorrow night. Contact me at seven seven two-148-1417 and i will read them to u.
 
Read THIS thread.
And THIS thread.
If the audio feature of a Gamin 396 or 496 is used, a "ground loop isolator" should be used.
The music input can also cause problems. Some RV-12 owners have disconnected the music wires.

It'll be a couple of days before I can get out to the airplane again. I just finished reading the two threads and will put information into practice and report back soonest.

Thanks...
