Thought I had a real good handle on this but apparently not. Currently have (example) 0.0.10 as a dept I'd like to toggle on/off. If I hit Channel, enter the sequence and press channel, it will go directly to that channel. However, while scanning and want to turn that channel off, I press the same sequence then ENTER, I get beeped at without anything happening. What am I doing wrong? I've tried writing to the scanner 3 time to no avail.
