Telephone External Ringer
The loud ringing bell option enables the voice first or ringing signal tone to be amplified without
the use of other manufacturers' equipment. The voice first and signal tone can be amplified on all
electronic and digital telephones equipped with HHEU PCBs and HESB. (See
Apparatus.)
The HESB automatically turns Off once the ringing call or voice first has been manually answered
from the electronic or digital telephone. This turn-off feature prevents audio feedback problems.
