Preset Tune
In this section you can tune presets of stations 
that broadcast only periodically, stations which 
were not found during the Autotune process. If 
you return to this preset in the future, and at 
that time is does not broadcast, the display will 
show 
STATION N OT AVAILABLE
.
Software Version
This section allows a visual check of software 
version installed in your TU 970.This might be 
helpful in case servicing of your tuner may be 
necessary.
Dynamic Range Control (DRC) Value
In this section you can set the level of compression of stations to eliminate the differences in 
dynamic range or sound level between radio stations. Popular music would normally be more 
compressed than classical music, resulting in 
possible different audio levels when changing 
from one station to the other. Setting the DRC to
0
means no compression,
1/2
indicates
medium compression and 
1
shows maximum 
compression. No compression is recommended, 
especially for classical music. Note that other 
radio stations may be far louder, and make 
therefore sure that amplifier levels are not set 
too high when changing from one station to 
another.
Manual Tune
In this section you can activate Manual Tuning, 
in case the Autotune function is unable to find 
any stations.You can also use Manual Tuning to 
assist in positioning the antenna for best reception of a specific station.
