Setting for use of a closed network

For maximum communications security, use a closed network. This limits
your machine to faxing to and from only other Pitney Bowes fax machines,
such as the 4100 or 4200, which can "present" the proper passcode.
Important: The passcode you use for closed network operation (and
limiting polling access; see page 144) is not the same as the
protection passcode.
Once set this way, your machine will disconnect calls coming in from other
machines.

Setting your fax machine's closed network passcode

1. Decide upon, and the write down, the four-digit closed network passcode
(0000-9999) you want to use and put it in a safe place.

If it is in Copy mode, press COPY/FAX to change to Fax mode.
