When you select the NTUN (continuous tuning using a narrow detection filter)
and BTUN (continuous tuning using a broad detection filter) options the screen displays
a window showing the frequency deviation of the sound carrier, this is variable
between 4.00 MHz and 9.00 MHz. To define it turn the rotary selector [4] to the desired
frequency deviation and press to validate.
When the LV function is selected, the speaker of the PROLINK-4C permits a
tone whose frequency depends on the level of the signal received. This is very useful
when installing antennas, since the user can locate the peak signal without having to
look continually at the monitor of the level meter.
