COMMUNICATION & SECURITY SOLUTIONS
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.

IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from
both the AC outlet and the telephone line. It is recommended that a surge protector be installed to pro-
tect against such surges.

* Note: For loud background noise, an optional “Push-to-Talk” button may be added, using a N/O or
N/C switch or the Viking SW-2 panel mount switch (DOD# 844). Important: JP2 must be removed.
** Note: An optional second 25AE Paging Horn may be added in parallel to the existing horn to increase
the paging area.

Programming
A. Normal Background Noise Environment
1. Under normal background noise levels, set the Paging Volume control so that the page may be heard as
required. Then set the Talk Back Volume control in the middle (12 o’clock) position.
2. Test talk-back to be sure that the HF-3W will switch between paging and talk-back for your desired operating
distance and noise level.
3. Adjust the Talk Back Volume control as necessary for your environment. The louder the background noise
level, the more you have to decrease the Talk Back Volume and the shorter your talk-back distance will be.
B. Loud Background Noise Environment
If the background noise is too loud for the HF-3W’s VOX circuit to operate properly, you will need to add a “push-
to-talk” button across screw terminals 9and 10, and remove shunt JP2. The “push-to-talk” button may be installed
at either the telco end or the speaker end. Use a normally open switch for the telco side or use a normally closed
switch for the speaker side.

Operation
When sitting idle, the HF-3W allows audio from a background music source or an existing paging system’s speaker
output to pass through to the paging horn.
Handsfree talk back paging is achieved by either accessing the two-way paging port, accessing the unused trunk
port, or coming off-hook on the single/multi-line phone. At this time, the background music is muted, a page alert tone
is given and paging with talk back is enabled.
C. Two-Way Paging Port Interface
If the Paging Input is to be connected to a paging port, the paging port must allow two-way talk path and provide
a contact closure during paging. Disable the Talk Battery by removing the Talk Battery Shunt (JP1) before con-
necting to the paging port.
D. Page Alert Tone
If a page alert tone is not required, set the Alert Tone Volume to minimum (see diagram on page 2).

If the equipment is causing harm to the telephone network, the telephone company may request
that you disconnect the equipment until the problem is resolved.
Connection to Party Line Service is subject to State Tariffs. Contact the state public utility com-
mission, public service commission or corporation commission for information.
WHEN PROGRAMMING EMERGENCY NUMBERS AND (OR) MAKING TEST CALLS TO
EMERGENCY NUMBERS:
Remain on the line and briefly explain to the dispatcher the reason for the call. Perform such
activities in the off-peak hours, such as early morning or late evenings.
It is recommended that the customer install an AC surge arrester in the AC outlet to which this
device is connected. This is to avoid damaging the equipment caused by local lightning strikes
and other electrical surges.
PART 15 LIMITATIONS
This equipment has been tested and found to comply with the limits for a Class Adigital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio fre-
quency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which case the user will
be required to correct the interference at his own expense.
FCC REQUIREMENTS
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA.
On the side of this equipment is a label that contains, among other information, a product identifier in
the format US:AAAEQ##TXXXX. If requested, this number must be provided to the telephone com-
pany.
The REN is used to determine the number of devices that may be connected to a telephone line. Ex-
cessive REN's on a telephone line may result in the devices not ringing in response to an incoming
call. In most but not all areas, the sum of the REN's should not exceed five (5.0) To be certain of the
number of devices that may be connected to a line, as determined by the total REN's, contact the
local telephone company. For products approved after July 23, 2001, the REN for this product is part
of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are
the REN without a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately
shown on the label.
The plug used to connect this equipment to the premises wiring and telephone network must comply
with the applicable FCC Part 68 rules and requirements adopted by the ACTA. If your home has spe-
cially wired alarm equipment connected to the telephone line, ensure the installation of this HF-3W
does not disable your alarm equipment. If you have questions about what will disable alarm equipment,
consult your telephone company or a qualified installer.
If the HF-3W causes harm to the telephone network, the telephone company will notify you in advance
that temporary discontinuance of service may be required. But if advance notice isn't practical, the
telephone company will notify the customer as soon as possible. Also, you will be advised of your right
to file a complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that
could affect the operation of the equipment. If this happens, the telephone company will provide ad-
vance notice in order for you to make the necessary modifications to maintain uninterrupted service.
