Commercial DCII Receivers

Hey guys, do you know if the Motorola 4800 and Digitrans boxes have a battery that needs to be periodically replaced ... like the consumer models?

I assume they do, but haven't seen anyone mention this ... or what it would take to replace a battery in one of these units.

Thanks!

Yes they all have batteries.

Thanks TVROPRO -- that would make sense. I guess it's buyer beware if you're looking to pick up one of these commercial units off eBay.

I wonder how a repair facility changes the battery without losing the receiver's ID. I'm sure that they do something more sophisticated than paralleling the existing battery with another battery?

There probably is a port on the board that they plug in an external power source that keeps the memory while doing it.

I know the older Ham Radio transceivers had that problem with batteries but basically just jumped the battery terminals with a low voltage supply in a way that you applied voltage to the battery holder to keep power to that circuit while you pulled the battery and changed it out.
