To test the telephone line (Telco or Telset) connection:
Press the [ALPHA] key. A string of O’s appears on the
display. (In the default display font, a zero has a slash
mark inside it to distinguish it from the letter O.)
The string of O’s indicates the following:
– The Telco or Telset telephone line connection of the
Omni 3200 terminal has been established, and
– The dual-tone multiple-frequency (DTMF) function
of the terminal modem has been automatically
turned on.

OOOOOOOOOOOOOOOO
To continue, press several numeric keys on the keypad
to duplicate the actual dialing of a phone number.
As you type, the numbers are appended to the string of
O’s. With each key press, you should hear the
corresponding DTMF tone.

OOOOOOOOOOOOO1234...
When you have verified that the DTMF function works
properly, press [FUNC/ENTER].
A zero, preceded by an asterisk and followed by a
comma (
*0,
), appears in the top right corner of the
display and the DTMF function is turned off.

To complete the Telco test, press [BACKSPACE].
The Telco function disconnects from the telephone line
(that is, it “hangs up”) and a string of ten asterisks,
separated by commas, appears on the display.
