Does changing the D-100 battery erase the memory?

[pierre smith]

Last weekend, I replaced my defective HS-34 module with a new one from Dynon. I also changed the D-100's battery while I had it out and after I finished, it read DSAB connectivity error...or something similar, and the 430W would not show on the D-100's HSI and had a 'no arinc 429 signal detected'.

Will changing the battery erase the D-100's memory? It also said 'no HS-34 installed' when it was installed. Ray re-programmmed the D-100 and now all is fine but I'm curious.

Thanks,

Nope,

Most likely changing the HS34's serial # caused this..

I have disconnected the battery before and never had an issue. Remember that the battery is also an optional component...

....because Dynon did call back and said exactly what you just did. The new serial # wasn't entered.

Thanks,
