I don't know if you've figured it out yet but the user set keys are:hold down P0 and turn on the radio, that simple. Also I have the same problem with the PL squelch.I've gotten nowhere fast. If you can help, I'd appreciate it.
rescuecomm, this series is a great little radio. For me, it is exactly the size I was looking for. Easy to carry, and not too obtrusive. I've been carrying a Motorola MT-1000, and I'm looking forward to the smaller package.
