The Q90 can share a telephone wall
jack with a regular phone (or an exter-
nal flashing device). This is especially
useful for household members that do
not use a TTY.
Connect an external telephone to the
jack in the back of the Q90 marked
TO PHONE (as shown above).
Note: The Q90 can also be used with
pay phones that have a data port. Plug
one end of the phone cord into the TO
LINE jack on Q90. Plug the other end of
the phone cord into the data port on the
pay phone.
