62 LINGO TECHNICIAN’S GUIDE
Using manual mode
To use the manual mode, you need access
to two telephone extensions of the tele-
phone system. You call Lingo from one
extension—the “first telephone”— and the
tests use it and the other extension—the
“second telephone”— to learn each tone.
To use manual mode
1
From the first telephone, access the
technician’s conversation.
2
Select action 7 (learn call progress
tones).
3
Select action 3 to use manual mode.

Lingo tells you if any voice mail ports are
active, and you can either try again later
or tell Lingo to disconnect all calls.
When all voice mail ports are clear,
Lingo begins the test.

When prompted, select action 4 (dial
tone), 5 (ring back tone), 6 (busy tone),

tone), and then follow the appropriate
