FEATURES
Your Radio Shack ET-152 Headset Telephone is a telephone head-
set and dialer that connects to your telephone line in place of a tele-
phone. The ET-152’s long headset cable lets you move freely while
you talk on the phone, and the adjustable microphone boom swings
back and forth so you can wear the headset over either ear.
Its features include:
Quick-Disconnect Plug — lets you disconnect the headset from
the dialer without disconnecting the call, so you can step away from
the phone without removing the headset. You can return to the con-
versation by simply reconnecting the headset.
Lapel Clip — lets you securely anchor the headset’s modular cord
to your clothing to prevent the headset from slipping.
Studio-Quality Electret Condenser Microphone — provides
clear transmission of your voice.
Adjustable Volume — gives you full control of the volume.
Touch Tone or Pulse (Rotary) Dialing— lets you use your ET-152
with either type of telephone service.
Hold Button — lets you put a call on hold.

with specialized telephone services, such as call waiting.
Ringer OFF/ON Switch — lets you turn the ringer on or off.
Last Number Redial — lets you automatically redial the last num-
ber dialed with the touch of a button.
Hearing-Aid Compatible — lets you use the ET-152 with hearing
aids that have a T (telephone) switch.
The ET-152 Headset Telephone has been tested and certified to

READ THIS BEFORE INSTALLATION
We have designed your ET-152 Headset Telephone to conform to
federal regulations and you can connect it to most telephone lines.
However, each device you connect to the phone line draws power
from it. This power draw is the device’s RingerEquivalence Number,
or REN. The REN is shown on the bottom of the ET-152.
If you use more than one phone or other device on the line, add up
all the RENs. If the total is more than five (or three in rural areas),
your phone(s) might not ring. If ringer operation is impaired, remove
one of the devices from the line.
FCC STATEMENT
Your ET-152 Headset Telephone complies with Part 68 of FCC
Rules
. You must, upon request, provide the FCC registration num-
ber and the REN to your telephone company. Both numbers are
marked on the bottom of the ET-152.
Note: You must not connect the headset telephone to:
• Coin-operated systems
• Party-line systems
• Most electronic key telephone systems

ADJUSTING THE HEADSET
1. Place the headset on your head as shown.
2. Adjust the headset band until it rests with almost no pressure
on your ear and the top of your head.
If the headset is loose, remove it and flex it inward slightly to
tighten it. If the headset is tight, gently pull the headset band
out to loosen it.

3. Hold the headset in place, and turn the microphone boom until
it is about even with your chin. Experiment until you find the
most comfortable position.
4. Route the headset’s modular cord through the lapel clip’s
channel and attach the lapel clip to your clothing. Leave
enough slack in the cord so you can move your head without
pulling the headset.
