Testing Your Telephone
You can test the lights and ringer on your telephone if you have
a Test/Program Switch. On some telephones, the Test/Program
switch has a spring. If so, you must hold the switch in the “T”
position to test the lights and ringer; the switch will
automatically return to the midpoint when released.

Slide the switch on the left side of your telephone to “T”.
The red and green lights alternately flash, and the ringer sounds.
NOTE:
If your switch has a spring, hold the switch in the
“T” position.
If your switch has a spring, release the switch. If there is no
spring, slide the switch back to the midpoint between “T”
and “P”.
