Automatic radio frequency update (AF)

The function automatically selects the strongest transmitter for the set radio station and can be activated for FM radio.

In order to find a strong transmitter the function may, in exceptional cases, need to search the entire FM wavelength.

If the set radio station is saved as preset then the function does not change transmitter even if automatic radio frequency update is activated.

To activate/deactivate, in the normal view for the FM source, press OK/MENU and select Alternative frequency.
