Tuning TMC 
Tap the Tuning button to toggle between Automatic tuning, Hold station, and 
Frequency input modes. 
 
In Auto tuning mode, the TMC receiver searches continually for the station that 
offers the best reception. The name and frequency of the station are displayed. 
Use the arrow keys to select a different station. As soon as another station has 
been found, its name and frequency are displayed. 
 
In Hold station mode, the current station is maintained. 
 
In Frequency input mode, you can directly enter a station’s frequency. Use the 
arrow keys to modify the frequency in steps of 0.1 MHz.
