Power Failure Telephone
Your Bizfon includes a jack (labeled Power Fail Telephone in

a power outage.

connects to CO line number 1, so be sure that one of your tele-
phone lines is connected to the jack marked “1-2.”

jack should be a non-AC powered telephone in order to work 
during a power failure.
