ROLMphone 300/600 User Guide

The faceplate is a paper template that identifies 
features that you access by pressing specific keys on 
your telephone. It shows which system features have 
been assigned to your telephone keys.

Your ROLMphone telephone has a separate line key 
for every extension that appears on your telephone. 
You use the line keys to answer and place calls.

Your telephone may have multiple extensions, each 
of which is assigned a separate line key. These line 
keys can be of different types. You will have at least 
one line key, called the primary line key, which 
corresponds to your extension. The status light that 
turns on when you pick up your handset is next to 
your primary line key.

You may also have another type of line, called a 
secondary line. You can use your primary line or a 
secondary line to make calls.

Your primary and secondary lines may also appear as 
lines (called multiple line appearances) on other 
people’s phones. Each person with an appearance of 
the line on his or her telephone has equal access to the 
line. Also, a call can be placed on hold at one tele-
phone, then retrieved at another telephone on which 
that same line appears. See “Hold” on page 2–17 for 
more information.

If you have a multiple line appearance on your tele-
phone, you will need to know how to tell if that line is 
in use. Your telephone tells you about the status of a 
line through the line key’s status light. See “Status 
Lights” on page 1–18 for more information.
