Dual radio operation
The TM9456 can be installed and programmed as two
radios, with one user-interface. This enables you to
switch between the radios, and access different
features and channels on those radios (for example,
channels that operate on different frequency bands).
You can also toggle modes that enable you to receive
and transmit on both radios at the same time.
Each radio in a system may be identified by a unique
name, which appears before all channel and group
labels.
This section covers:

About the foreground and
background radio
The TM9456 can be installed and programmed as two
radios, that can be accessed via the user-interface. In
such a dual-radio system, one radio is always at the
foreground, and one at the background. If monitoring
both radios (dual receive), the speaker volume of the
background radio is quieter than the speaker volume
of the foreground radio.
To access features on the background radio (such as
change the channel), you must first change that radio
to the foreground.
