FEATURES
Your RadioShack Handsfree Headset Amplifier frees your hands to
do other things while you talk on the telephone. You can also use it
with a computer that is equipped with a sound card. The micro-
phone boom is adjustable, so you can wear the headset over either
ear.
The headset’s control unit connects directly to a standard modular
phone jack, and allows you to switch between the phone line and a
connected computer.
It also has these features:
Built-in Earpiece and Microphone Output Volume Controls —
let you adjust the volume levels you hear through the headset and
send through the microphone.
Built-in Tone Control — lets you adjust the tone level you hear
through the headset.
Microphone Muting — lets you turn the headset’s microphone off
to prevent callers from hearing a private conversation.
Adjustable Microphone Boom — lets you wear the microphone
on the right or left side.
Quick-Disconnect Plug — lets you disconnect the headset from
the phone without disconnecting the call, so you can step away
from the phone without removing the headset, then reconnect the
headset to return to the conversation.
Mono Earpiece with Soft Foam-Filled Cushion — reduces ambi-
ent sound to provide a comfortable listening experience.
Audio Output (AUX) — lets you connect the control unit to an au-
dio recorder.

automatically when it detects a voice.
Adjustable Headband — adjusts to fit almost any head.
Lapel Clip — lets you securely anchor the headset’s cord to your
clothing to prevent the headset cord from pulling the headset.
4-Foot Cable — lets you move freely without disconnecting the
phone. If you need a longer cord, your local RadioShack store has
a wide selection of cords.
The Handsfree Headset Amplifier has been tested and found to
comply with all applicable ETL and FCC standards.
Your headset is ETL listed to UL standards and meets all applica-
ble FCC standards.
READ THIS BEFORE INSTALLATION
We have designed your control unit to conform to federal regula-
tions, and you can connect it to most telephone lines. It has a ring-
er equivalence number, or REN, of 0.5B. If you are using more
than one phone or other device on the line, add up all the RENs. If
the total is more than five, your phones might not ring. In rural ar-
eas, a total REN of three might impair ringer operation. If ringer op-
eration is impaired, remove the device from the line.

FCC STATEMENT
This equipment complies with the limits for a Class B digital device
as specified in Part 15 of
FCC Rules . These limits provide reason-
able protection against radio and TV interference in a residential
area. However, your equipment might cause TV or radio interfer-
ence even when it is operating properly. To determine whether
your phone is causing the interference, turn off your Handsfree
Headset Amplifier. If the interference goes away, your phone is
causing the interference. To eliminate interference, you can try one
or more of the following corrective measures:
• reorient or relocate the receiving antenna
• increase the distance between the equipment and the radio or
TV
• use outlets on different electrical circuits for the equipment and
the radio or TV
• contacting your local RadioShack store for help
Shielded cables must be used with this unit to ensure compliance
with the Class B FCC limits.
If you cannot eliminate the interference, the FCC requires that you
stop using your Handsfree Headset Amplifier.

PREPARATION
INSTALLING/REPLACING BATTERIES
You need two AA batteries (not supplied) to power the Handsfree
Headset Amplifier. For the longest operation and best perfor-
mance, we recommend alkaline batteries, available at your local
RadioShack store.
Cautions:
• Use only fresh batteries of the required size and recommended
type.
• Do not mix old and new batteries or different types of batteries.
•Note: To use battery power, adapter cord should not be con-
nected to the unit even if there is no AC power.
Follow these steps to install batteries.
1. Remove the screw from the bottom of the control unit, then
slide off the battery compartment door in the direction of the
arrow.
2. Put two AA batteries into the compartment as indicated by the
polarity symbols (+ and –) marked inside.

3. Replace the battery compartment door and secure it with the
screw.
When the headset’s sound weakens or distorts, adjust EARPIECE
VOLUME. If the sound does not improve, press MUTE. If the MUTE
indicator does not light (or lights dimly), replace the batteries.
Cautions:
• Always remove old or weak batteries. Batteries can leak chem-
icals that can destroy electronic parts.
• Dispose of old batteries promptly and properly. Do not burn or
bury them.
USING AC POWER
You can power the control unit using a 6-volt, 150-mA AC adapter
and a size B Adaptaplug®(neither supplied). Both are available at
your local RadioShack store.
Cautions:
You must use a Class 2 power source that supplies a
regulated 6 volts DC and delivers at least 150 mA. Its
center tip must be set to positive and its plug must fit
the control unit's DC 6V jack. Using an adapter that does not
meet these specifications could damage the control unit or the
adapter.
• Always connect the AC adapter to the control unit before you
connect it to AC power. When you finish, disconnect the adapt-
er from AC power before you disconnect it from the control
unit.
Follow these steps to connect AC power.
1. Attach the Adaptaplug to the AC adapter with its tip set to posi-
tive.

2. Set the adapter’s voltage switch to 6V.
3. Insert the plug into the DC 6V jack on the back of the control
unit.
4. Plug the adapter into a standard AC outlet.

2. Plug one end of the supplied coiled cord into the TEL jack on
the back of the unit and the other end into the telephone’s
base.
3. To connect a computer, plug one end of the supplied PC con-
necting cable into the PC jack on the back of the control unit,
and the two ends into the computer’s sound card (red micro-
phone pin into microphone jack and black LINE OUT pin into
LINE OUT jack).
Notes:
• If your sound card does not have a LINE OUT jack, use its
SPEAKER jack instead.
• Use another cable (not supplied) to connect the modular
telephone line jack to the computer’s modem. You can use a
duplex adapter to connect the existing line cord and the
modem line to the modular telephone line jack.
• Only sound from the sound card’s LINE OUT (or SPEAKER)
jack is amplified (and can be recorded using a connected
audio recorder).
4. To connect an audio recorder, plug one end of the supplied
audio cord into the AUX jack and the other end into the device’s
input jack.
Note: It is illegal in some states to record a conversation with-
out the consent of all parties to the conversation, including the
phone company. Check the laws in your area before using the
two-way record feature.
5. Plug the headset’s cord into the HEADSET jack on the right side
of the control unit.
ATTACHING THE HEADSET HANGER
The Handsfree Headset Amplifier includes a headset hanger that
gives you a convenient place to store the headset when you are
not using it.

To attach the hanger, make all connections, then push its end into
the hole on the back of the control unit until it clicks.
Note: If you try to attach the hangar before all connections are
made, the hanger might interfere with plug insertion.
ADJUSTING THE HEADSET
1. Place the headset over your head with the earpiece on either
ear.
2. Adjust the headset band until it rests
with almost no pressure on your ear
and the top of your head. If the head-
set is loose, remove it and push the
band in slightly to tighten it. If it is
tight, gently pull the band out to
loosen it.
3. Hold the headset in place and adjust
the microphone boom until it is even
with your chin, with the white dot
toward your mouth. Experiment until
you find the most comfortable posi-
tion.
Note: The microphone boom swivels
on the headset. Do not bend the
microphone boom while you adjust it.

4. Attach the lapel clip to your clothing. Leave enough slack in the
cord so you can move your head without pulling the headset.
Note: To avoid having to repeat these adjustments, when you are
not using the headset, place it on the headset hanger and wind the
cable around the hanger.
Listening Safely
To protect your hearing, follow these guidelines when you use the
headset.
• Set the volume to the lowest setting before you begin listening.
After you begin listening, adjust the volume to a comfortable
level.
• Do not listen at extremely high volume levels. Extended high-
volume listening can lead to permanent hearing loss.
• Once you set the volume, do not increase it. Over time, your
ears adapt to the volume level, so a volume level that does not
cause discomfort might still damage your hearing.
