From a voice terminal, touch the fifth button down in the leftmost row
of buttons (Intercom-Ring) without lifting the handset.
The red light next to the button goes on.
Lift the handset.
The green light next to the button goes on.
Dial your partner’s intercom number.
You hear intermittent ringing.
Wait for your partner to answer before speaking into your handset.
When the call comes through on the called voice terminal, three short
rings sound, the red light glows steadily next to the fourth button down
in the leftmost row of buttons
(Intercom-Voice),
and the corresponding
green light flashes until the handset is lifted.
When your partner lifts the handset at the called voice terminal, verify
two-way communication, and then hang up the handsets at both voice
terminals.
The lights on both voice terminals go out, and the red light goes on next
to the third button down in the leftmost row of buttons.
Repeat this procedure for every voice terminal you want to test.
