When Tone Identification is in single tone, all accepted metal types produce
the same audio pitch during searching. If the Discrimination is set to reject a
specific target range, that range may not produce a beep of any pitch. Reject-
ed targets often do not produce any tone (silence).

1. Press Options and use up or down arrows to select Tone ID.
2. Press + & - to select the type of Tone Identification desired.
3. Press Options to exit or wait 10–15 seconds for the options mode to
automatically time out.
