When I received my TT030 last month, I discovered it does not have a clock battery installed. The velcro strip to mount it to is still stuck to the inside of the case. I want install a battery, but I am not certain which jumper the battery wire will plug into.

Could someone point me in the right direction? Is it J400?

Thank you.

Yes, it's J400. I've forgotten whether the key is on the ground or positive side though. I think it's the same as old PC motherboards.

1 = +
2 = not connected
3 = ground
4 = ground

I thought it was J400. I appreciate you guys confirming it.

Thank you !
