The Nortel Norstar telephone has a testing mode that allows for testing a telephones speaker.

To test a telephone set speaker press the Feature button ( <or> ) followed by pressing 805 then press either the pound sign button or NEXT until the LCD Display reads Speaker Test.

To proceed with testing the speaker, press either the LCD Display button directly below the word TEST or press the Hold button ( <or> ).

Now through the telephone speaker one should hear a page tone at maximum volume level. Otherwise, there is a problem with that telephones speaker.

Pressing any telephone button now will end the speaker test..
