The DSC interface module is a board providing an addi-
tional interface on the radio backplane to connect an
NMEA con troller. T he DSC module (with co nnected NMEA
controller) may control radio parameters. Icons in the
menu header indicate the current state of the DSC module
(see sect. 3.2 Operating Concept). If the DSC module is
active, it has control over the following radio parameters:
• Communication mode (always FF)
• Preset Page (always 0)
• Modulation mode
•Frequency
•Power
• PTT (see also sect. 3.4.11 Menu Radio MTC 6/7
(3006))
If the DSC module is active, the operator may not change
these parameters until the DSC module is deactivated.
Switching the DSC mode OFF is the only possibility to
deactivate a DSC module once activated.
