DETUNE decreases your amulet of communication's sensitivity to
the magical weave, effectively tuning it out. After you DETUNE
your amulet, you will no longer be able to send or receive messages
via the amulet of communication until you increase its sensitivity
again using the TUNE function.
TUNE will return sensitivity to your amulet of communication after it has
been DETUNEd, such that you will once again be able to send and receive
messages sent by amulet.
* You must be wearing your amulet of communication to use this command.
