DSC SETUP menu

The [DSC SETUP] menu sets up the system's DSC features.
MMSI: Ship's MMSI (display only).
SIG DETECT S-LEVEL: Adjust the carrier sense threshold for DSC and PSTN. DSC transmission
is delayed if the carrier level is lower than the level set here. Also, determine whether a DSC fre-
quency is in use or not. A DSC message is not transmitted when the signal strength of the DSC
frequency is lower than that set here. When the DSC frequency becomes clear, the DSC message
is sent.
The carrier is checked at a specified interval during PSTN communications, and if the carrier level
is lower than set here the line is disconnected.
Procedure
1) Select [SIG DETECT S-LEVEL].
2) Push the Rotary knob to show the [SIG DETECT S-LEVEL] adjustment window.
3) Rotate the Rotary knob to set the level.

sage is received.
