for some odd reason, I most likely hit a button but, mine can do that. It's power save mode, thats what the display says, when you turn it on, it counts down than find out how to enable that and it should work...
"Your scanner features a power save circuit that is automatically activated after about 30 seconds if you have manually select a channel. The power save mode works by allowing the receiver to 'sleep' briefly while waiting for a call on the selected channel and will also turn the backlight off. The power save circuit is disabled when the scanner is tuned to a channel in program mode, scanning, or searching." (Easier to read Pro-97/2055 Scanner Manual.) >
