Distress Alarm (0 - 31) - Furuno FS-1575 Service Manual

The Submenu-2 "SIG DETECT S-LEVEL" is used to make setting of frequency
detection levels in order to activate this function. "0" represents the minimum detection
level, while "100" represents the maximum level.
For example, setting this Submenu-2 to "0" may activate the "BUSY CHECK function"
due to noise to disable the transmission of DSC message. In this case, cancel the
transmission of the message once, and then retransmit it.
• The BUSY CHECK function is not available to transmit a Distress alert.
• Forced message transmission from the "CH BUSY !" status is not allowed.
Cancel the transmission of the message once and transmit it again.
• Frequency is monitored with the RX board regardless of DSC transmission
frequency.
Reference)
To monitor frequency, temporarily set the DSC transmission frequency to the
reception frequency of the RX board, mode to TLX, and RF GAIN to Max.
