External and extension 
telephones 8
An external telephone is available only for 
MFC-1810 and MFC-1811.
 
Connecting an external or 
extension telephone 8
You can connect a separate telephone 
directly to your machine as shown in the 
diagram below.
 
1 Extension telephone
2 External telephone
3 Protective Cap
Before you connect an external telephone, 
remove the protective cap (3) from the EXT. 
jack on the machine.
When you are using an external telephone, 
the LCD shows Telephone.
For Fax/Tel mode only 8
When the machine is in Fax/Tel mode, it will 
use the F/T Ring Time (fast double-ringing) to 
alert you to pick up a voice call.
Lift the external telephone’s handset 
(MFC-1810 and MFC-1811 only) or the 
machine (MFC-1815 only), and then press 
Hook or Hook/Hold to answer.
Using a non-Brother cordless 
external handset 8
If your non-Brother cordless telephone is 
connected to the telephone line cord (see 
Connecting an external or extension 
telephone on page 48) and you typically carry 
the cordless handset elsewhere, it is easier to 
answer calls during the Ring Delay.
If you let the machine answer first, lift the 
cordless handset and then go to the machine 
so you can press Hook or Hook/Hold to 
transfer the call to the cordless handset.
Not all brands of cordless telephones are 
compatible for use with your machine.
