T200 is really sensitive to the voltage on the nicad.

First, when I plugged in AC power the unit powered up on it's own. Then when I tried to power down, the screen was left with two horizontal lines and the speaker had a low hum. In the end, I cut the leads to the capacitor and I am running without an internal backup battery. This restored everything to normal. > >
