Beyond the basics

Setting security transmission

Your fax’s security transmission feature provides extra assurance that your documents go where you’re sending them. When this feature is activated and your machine sends a fax, the machine compares the last four digits of the dialed number to the other unit’s Subscriber ID (the phone number at the top of that unit’s transmissions; see page 1.18). If these digits match, your call goes through. If they don’t, your machine disconnects the call and prints an error message telling you to check the condition of the remote unit.

Before you activate this feature, please consider:

∙Not all fax machine owners enter their phone numbers in their Subscriber IDs. — Indeed, some machines don’t even have a Subscriber ID. So, with security transmission activated, your machine would disconnect its calls to such machines.

∙Access codes can cause confusion. — If an autodialer entry ends with a long-distance or other access code, activating this feature prevents calls to that fax. (After all, the other fax’s users won’t put your codes at the end of their Subscriber IDs.)

Note: In the following instructions, your fax’s display abbreviates Transmission as Tx.

1. If the machine is in Fax mode, proceed to step 2.

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

2. Press PROGRAM, J, 1, 0, ENTER. The display shows the current setting:

Security Tx: Off

Program/Enter

If the setting you see is acceptable, skip to step 4.

Otherwise, proceed to step 3.

3. To change the setting, press PROGRAM once or twice until your chosen setting appears. In this example, we’ve chosen On.

Security Tx: On

Program/Enter

4. Press ENTER to save the setting.

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 Muratec fax machines which can “present” the proper passcode.

Important: The passcode you use for closed network operation (and

limiting polling access; see page 2.33) 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 then write down, the four-digit closed network passcode (0000- 9999) you want to use and put it in a safe place.

2.

3.

Set Passcode

Passcode :0000

If the setting you see is acceptable, skip to step 5.

Otherwise, proceed to step 4.

4. Use the numeric keypad to enter the desired four-digit closed network passcode.

Set Passcode

Passcode :5627

5. Press ENTER to save the setting.

Note: To turn off the closed network passcode and return to normal fax reception, change the code to 0000 by repeating steps 1–5 and entering 0000 in step 4.
