Squelch; Dsl Freq Mode - AALogic TriTone User Manual

Gain increases the sensitivity of the amplifier. This helps when the tone is weak such as
identifying cables. Volume just makes the sound from the speaker louder. This helpful in
noisy areas. If the tone is faint, increase the GAIN rather than the volume. If you can hear
tone but it is not loud enough, increase the VOLUME.
