AFTER A POWER FAILURE:
When power is restored the display will flash alternately between “SELECT LANGUAGE” and “1.ENG 2.ESP” for about 10
seconds then return to the normal “TOTAL:XX NEW:XX” (XX being the number of calls in the caller ID list). Your date and
time will not show back up until the next call comes in and is captured by the caller ID. From then on it will be set and
remain on the display.
CALLER ID INFORMATION:
Caller ID information comes in between the first and second rings. If you answer your phone before the caller ID info gets
there you may hear a “screech” similar to a fax or modem tone. That’s the caller ID data.
The red light labeled “NEW CALL” lets you know someone called - even if they didn’t leave a message. Press the
“CALLER LIST” button on the right and then the “REVIEW” up or down buttons to scroll through the list of incoming calls.
Once the entire list has been reviewed, the “NEW CALL” light will go out. New calls will reactivate the red light, and will
need to be reviewed before it will turn off again.
If you want to return a call to a number on the list:
ON CAMPUS (4 digit) numbers: Pick up the handset (or press “SPEAKERPHONE”), scroll to the number and press
“DIAL”.
OFF CAMPUS NUMBERS: You will have to inset the 9 and whatever other numbers (1, 731, etc.) you would normally dial
that are not displayed when you scroll to the number in the Caller ID list. After entering the proper extra
digits, you can scroll to the number you want to return and press “DIAL”.
If you want to delete a number on the list, press the “DELETE” button twice and the number will be erased. If you want to
delete all listings, press and hold the “DELETE” button until you see “DELETE ALL?” in the display, release the “DELETE”
button and press it again.
