Default Condition: All DTMF Decoder Mutes are ON (enabled)
Examples:
DTMF Muting is usually left ON (enabled) to prevent annoying DTMF digits
from being repeated, and to prevent listeners from learning command codes.
If it becomes necessary to signal some device that is monitoring the
transmitter, you may turn OFF the muting associated with the desired
receiver(s).
