Allow Employees to Respond to Paging
Messages, Handsfree!
Features
The
HF-3W
handsfree paging unit allows employ-
ees to respond to a paging message without
reaching for the telephone. It is perfect for use in
city desks, shipping and service applications where
quick answers are needed.
The
HF-3W
generates its own talk battery and will
interface with unused trunk ports on PABX’s and
key systems, and single line phones, as well as
some telephone systems with a two-way paging
port and a contact closure.
Simply page the intended employee with a ques-
tion and they can respond by speaking toward the
paging horn.
Paging and talk-back volume sensitivity controls
are provided.
