What are these buttons for?

[Lamplighter]

I have a few buttons on my 1974 Robyn CB. A “Tune” switch with a “0” next to it and a “+” or “-“ above and below.
A “Tone” button with a low or high option
and a Loc/Dx button.
Does anyone know what these are for? I haven’t installed it yet but likely will this weekend.

Tune (Delta Tune) is the clarifier ..used for fine tuning, usually used on ssb

Tone, is used to control how the radio sounds to you..does not affect your signal going out, just how people sound to you.

Loc/DX switch is the same as a RF GAIN knob...When flipped to Loc (local) you will only hear stations that are relatively close by...weaker stations are filtered out...flip to DX, and this will let you hear the weaker stations or the ones farther off....however, along with letting you hear the weaker stations, you will also be hearing more noise....

Thank you!
