Currently, I get nothing out of it whatsoever. I discovered that one of the surface-mounted fuses had blown so I've replaced that and I'm still getting nothing, though I am now at least getting a low voltage (about .5V) at components on the board when it's powered on. This unit has a rechargable ni-cad battery in it (that I'm pretty sure no longer holds a charge) and I'm curious whether a functioning battery is required for normal operation.
