AiPhone AT-305 Modification

Hello everyone.

I am working on a project to add a LED indicator light to an AiPhone At-305 to illuminate when the call button is press.

I understand the unit is 6v-DC. My intention is to start with a 6v 6mm LED and located the pins which receive the voltage once the call button is pressed.

I am wondering if anyone has tried this project to previously and could give me any insight.

I will post my results once I have finished.
