The link to the video is dead. I too would like a picture of how you jumpered the board. This is a way cool mod

Been some years so going from memory. I don't want to pop it open again.


Red lines are where you need to jumper. One or the other. NOT BOTH at the same time.
OR put a three way switch like i did.
So the three settings are...

No jumpers Standard
Top jumper Geo
Bottom jumper Medical

Do you have any idea what those extra LRED contacts on the bottom edge are for? Some sort of unused red LED flash for the screen? Curious if you experimented with those as well when you had it open

No idea. Given there is a + and - , power for something. Extra LEDs? for some display option never realized?

Would be worth monitoring them with a multimeter and see if they are active or become active during certain sounds?

Medical maybe? Heartbeat?
