Setting up your area code (USA only)
5
When returning calls from the Caller ID 
history your machine will automatically dial 
“1” plus the area code for all calls. If your local 
dialing plan requires that the “1” not be used 
for calls within your area code enter your area 
code in this setting. With the area code 
setting, calls returned from the Caller ID 
history to your area code will be dialed using 
10 digits (area code + 7-digit number). If your 
dialing plan does not follow the standard 1 + 
area code 
+ 7-digit number dialing system for calling 
outside your area code, you may experience 
problems returning calls automatically from 
the Caller ID history. If this is not the 
procedure followed by your dialing plan, you 
will not be able to return calls automatically.

Special line considerations

Roll-over telephone lines
5
A roll-over telephone system is a group of two 
or more separate telephone lines that pass 
incoming calls to each other if they are busy. 
The calls are usually passed down or “rolled 
over” to the next available telephone line in a 
preset order.
Your machine can work in a roll-over system 
as long as it is the last number in the 
sequence, so the call cannot roll away. Do not 
put the machine on any of the other numbers; 
when the other lines are busy and a second 
fax call is received, the fax call will be sent to 
a line that does not have a fax machine. Your 
machine will work best on a dedicated 
line.
Two-line telephone system
5
A two-line telephone system is nothing more 
than two separate telephone numbers on the 
same wall outlet. The two telephone numbers 
can be on separate jacks (RJ11) or mixed into 
one jack (RJ14). Your machine must be 
plugged into an RJ11 jack. RJ11 and RJ14 
jacks may be equal in size and appearance 
and both may contain four wires (black, red, 
green, yellow). To test the type of jack, plug in 
a two-line telephone and see if it can access 
both lines. If it can, you must separate the line 
for your machine. (See Easy receive in 
chapter 5 of the Basic User’s Guide.)
