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 dialled number to the other
unit’s Subscriber
ID (the phone number at the top of that unit’s transmissions; see
page 1.19). 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 ID s. —
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 autodialler 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
ID s.)
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 2.32) 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. 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.
3. Press PROGRAM , J , 0, 8, ENTER . The display shows the current code:
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.
