operate totally hands free. All you need to do is talk and the HT900
portable will automatically transmit for you.
Scan/priority scan
The
HT900 Series portables have the facility to scan for an active (or
free) channel. When the channel is found, the radio will automatically
select it channel 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 HT900 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

radio systems use a "repeater" to increase the system's range. However
when you go outside the range of the repeater, communication with
