How to start a new session
When another session is active:
• When sending the distress alert
, all sessions except the distress alert TX session
automatically close then the distress alert TX session starts.
• When doing an RT session or sending a non-distress DSC message
, the currently
active session is put on hold then the RT session or non-distress DSC message TX
session starts.
• When receiving a DSC message
, its session is put on hold.
When no other session is active:
• When sending the distress alert
, all sessions except the distress alert TX session
automatically close then the distress alert TX session starts.
• When sending a non-distress DSC message
, its session becomes the active ses-
sion.
How to switch sessions
When one session is active and another message arrives, a new session for the re-
ceived message does not start automatically. Only one session can be active. For ex-
ample, when you are transmitting a DSC message and another message arrives, the
option [ACTIVE] appears to indicate the start of a new session.
