Behnke AT6 manual
Use the machine room
telephone or (if not available)
connect an analogue test tele-
phone to the dialling unit to
make a call to the cabin (press
"1"). If the transmission works,
it is necessary to check if the
selected protocol (parameters
*21* to *24*) and the receiver
are suitable for each other.
Change the position of the
antenna for the established
connection until an optimal
antenna position is deter-
mined.
Do not mount the antenna too
close to the dialling unit, other
lines or sources of interfer-
ence.
Check the connection via the
telephone line.
Check the SIM card by insert-
ing it into a normal cell phone.
