Your machine has a number of features to enhance the security of your fax commu- nications. These security features can help you let your private fax documents stay private, avoid unwanted outside communication and even protect against unautho- rized use of your machine — as well as control its authorized use.

The key to it all: the passcode

Your machine has a protection passcode system which, as you’ll see, is central to the machine’s security capabilities. Normally, this four-digit passcode is set to 0000 (four zeroes). This turns off passcode operation. But, if you set the passcode to any- thing besides 0000, this passcode provides access to numerous other security capabilities we’ll describe in succeeding pages.

To set your machine’s passcode:

1 Decide upon, and then write down the four-digit passcode (0001–9999)you want to use and put it in a safe place.

Important: Do not use 0000. This turns off passcode protection.

2 Press /PROGRAM, J, 1, 6, ENTER. The LCD will show:

Protect Passcode

3 If you are creating the passcode, use the numeric keypad to enter 0000. If you are modifying an existing passcode, enter the existing passcode.

4 Press ENTER.

5 Enter the desired four-digit passcode. Here, we’ve entered 6296:

Protect Passcode

6 Press ENTER to save the passcode.

Note: Anytime you want to turn off the passcode, change the passcode back to 0000 by repeating steps 1–6 and entering 0000 in step 5.

Beyond the basics

Locking up tight: operation protection

Important: For this feature to work, you must have set the passcode, as described in the left column.

Because this is a powerful machine you have here — and, besides, you’re paying for its phone calls — you may not want just anybody to use it. That’s why we’ve pro- vided operation protection. When this feature is activated, only those who enter the proper passcode (see “The key to it all: the password,” left column) can send faxes from — or even make settings on — the machine.

Activating operation protection

1 Press /PROGRAM, J, 1, 7, ENTER. The LCD shows:

Set Opr. Protect

2 Use the numeric keypad to enter the passcode. Here, we’ve entered 6296:

Set Opr. Protect

3 Press ENTER. The LCD shows:

Opr.Protect: Off

Program/Enter

4 If the setting you see is acceptable, skip to step 6. Otherwise, proceed to step 5.

5 To change the setting, press or /PROGRAM once or twice until your desired setting appears. In this example, we’ve chosen “On.”

Opr.Protect: On

Program/Enter

6 Press ENTER to save the setting.
