automatic tuning.

 

  If the automatic tuning does not stop on the exact frequency of the station, for example, 

it stops on 100.9MHz instead of 100.8MHz, use the manual tuning method to "fine tune" 

to the exact frequency of the desired station. 

  You can also direct enter the frequency by using the remote control. 

 

For  example,  88.1MHz  (enter  881  with  remote  control),  100.8MHz  (enter  1008  with 

remote control).
