You can change numerous transceiver settings with the
MC-53DM or MC-45DM microphone without using the
transceiver buttons or controls. DTMF tones are used for
this remote control operation. First switch Microphone
Control ON using Menu Set-up {page 78}.
Note: Audible DTMF tones from other transceivers near you may be
picked up by your MC-53DM or MC-45DM microphone. If so, this could
prevent the functions from working correctly.
The following table shows what function is switched ON
and OFF or which setting is changed by pressing the
DTMF keys.
