Using the Radiophone

The Radiophone display
The display provides you with visual indication of the selected channel numbers, and
the transmit and receive frequencies. In addition, it shows you messages that will
assist you when operating your Radiophone. A detailed description of all the
messages can be found in section 12, Display messages.
The display– and button legends of the control head– are back-lit to give you the
clearest view. If necessary, the brightness can be adjusted to suit your needs, refer to
Dimming the display indicators on page 4-6.
This section explains what the option codes mean and how to reveal the option codes
on the display.
The display contains two rows of information. Each row is split into three groups.
What you see in each group depends on the Radiophone mode selected.
