Telephone operation

Basic phone operation

This phone comes programmed to use line 1 
(default prime line) for calls if you do not press a  
line button. (To change the prime line, see

LINE on page 39 of the installation guide.) When 
you answer a call, the phone automatically selects 
the ringing line.

The four indicators above the 

[LINE] keys will 

indicate the state of the corresponding phone line.
The four 

LINE lights have two colors:

Green is for outside calls.

  a. On when the line is in use on this phone. 
  b. Flashes slowly when the line is on hold.

c. Flashes rapidly when there is a transferred 

call on the line.

d. Flashes quickly when there is an incoming 

auto attendant transferred call on the line.

e. Flashes rapidly when there is an incoming 

call on that line.

Red is for the state of the phone system.

a. On when another phone is using the line.
b. Flashes slowly when the line is held by 

another phone on the same system.

This phone will automatically make and answer 
calls in the mode (speakerphone or headset) you 
programmed (see 

AUTOMATIC MODE on page 

39 of the installation guide). Follow the direction 
below to choose a mode manually. If the phone 
is in use on one line, any other calls made or 
answered will use the same mode already in use.
