Tricaster 455 Motherboard CMOS Battery

[Marty01]

Can someone tell me what battery is used on the Tricaster 455 motherboard? System has been upgraded to a 460, but originally a 455 motherboard. I can't read the number on it because it's so reflective and shiny. I figure I need to change it since the system is about 5 years old. I want to have the right one on hand before I pull this one out.

Thanks,
Marty Davis

It should be a CR2032 coin battery.

I wonder how long the BIOS memory remains entact while you change the battery? It doesn't make sence to have the TriCaster powered while the battery is changed. I'm not even sure if one could change the battery while powered.

I think I need to change the battery on my 410. How long can the battery be out? Do you unplug the Tricaster when replacing? Is there any documentation out there on this?

Thanks.

I'm thinking I need to replace the CMOS batteries in both my 3Play and 860. I still never heard the procedure concerning losing CMOS memory or not. I'm guessing I should power them up for a time before shutting down to replace the batteries. Hopefully, that would create some time for changing the battery before losing the CMOS settings. Anyone?
