Tuner Setup Menu
Each tuner has a separate menu and can be controlled independently. The menu structure for all tuners
are identical thus the following descriptions are relevant for all three tuners. A description of each of
the setup features is detailed below:

Band:
The user can select the broadcast band to receive. Each tuner is capable of receiving AM,
FM, NOAA Weather band, Dual NOAA Weather band and Public Service band. The dual NOAA
weather band feature allows the user to receive two NOAA weather band channels on one tuner.
In the dual band receiver mode, frequency #1 audio is output to the left channel and frequency
#2 audio is output to the right channel. Dual NOAA weather band mode requires a software key
to enable the feature.
Frequency:
This menu allows the user to program the received frequency for each band.
The channel spacing and band limits are determined based on the band and region settings.
Frequency dual:
This menu is only used in the dual NOAA weather band mode. This menu allows
tuning of the second frequency for this tuner. Recall that the audio output of frequency #2 will only
be available on the right channel while the audio for frequency #1 will be available on the left
channel, and this feature requires a software key to enable the option.
Auto Squelch:
This menu item will allow the audio levels to be squelched when the RSSI level is
below a particular threshold. For Tuner #1, the MPX composite level will also be squelched. During
Dual NOAA Weather band operation, the squelch will only trigger on the first frequency selected,
and not on frequency #2.
Squelch Level:
This control allows the user to determine the RSSI level where the audio squelch
will occur. This control has units of dBµV in 1dB steps. If the received RSSI level drops below the
