While using location scanning, anytime I try to hold a channel it gets stuck on Dept. site hold. Every. Time. Only way to fix it is to turn the whole thing off, let it boot up again. Using the search by area is almost impossible, because if you hold the wrong "dept." you're stuck on it. Followed all the instructions on here already posted, they don't work. You can turn "system" and "chan" on and off put it won't turn off "dept.". Is the thing just glitched out? Why when a press the button to turn it off it just refuses to work? Infuriating.
