(0,1), (1,0): Normally, RDS systems are locked out,
but the user can temporarily switch RDS on to allow
RDS operations to take place. RDS will
automatically be locked out again after a certain
time, which is stored in System Switch 03. Note that
if an RDS operation takes place, RDS will not switch
off until this time limit has expired.

1: Each Quick dial number on the list is printed with
the dedicated TX parameters (10 bytes each).
The first 10 bytes of data are the programmed
dedicated TX parameters; 34 bytes of data are
printed (the other 24 bytes have no use for service
technicians).
Do not change the setting.
If the machine is unable to print fax messages due
to a mechanical problem, change this bit to 0 to
transfer all messages in the memory (including
confidential rx messages) to another terminal.
Always reset this bit to 1 after transfer. However,
this bit can be left at 0, if the customer's key-
operators want to transfer the files themselves.
This machine does not support the confidential RX.
