Automatic CW ID (*5 34)
When Automatic CW ID is turned on, the interconnect will automatically
send the ID Message at programmed intervals only when the interconnect
sees activity. If the ID interval has elapsed, the SDI-50 will
automaticly send the ID message the next time it sees activity on the
channel. If this function is turned on, you must also program the
Station ID in the ID Message area (*9 4), and the ID Interval (*1 6).

Auto Answer (*5 35)
Auto Answer allows the interconnect to automatically answer an
incomming call from the phone. The Auto-Answer provides three
separate functions:
a. Land line to mobile selective signaling
b. Dial up remote control
c. Remote programming capability.
When auto answer is turned on, remote control and remote programming
are always active while selective signaling and Ring Out may be turned
on or off. If auto answer is off, then the interconnect will signal
the mobile and wait for the mobile to send the connect code before the
call is answered.
