Scan/priority scan
The HT500 Series portables have the facility to scan for an active (or free) channel. When the channel is found, the radio will automatically select it for you. Priority scan will allow you to select one channel in the scan list that is treated as a "Priority". It will be checked more frequently than all other channels in the list.
Programmable channel monitor button
If you have channel protection enabled on your HT500 portable, all signals other than your own networks will be filtered out. This can be temporarily disabled allowing you to monitor all signals on your channel.
Talkaround
