FEATURES
Your RadioShack ET-153 Super Lightweight Headset Telephone is
a complete telephone with a headset and a dialer that connects to
your telephone line. The ET-153’s headset lets you keep your hands
free to do other things while you talk on the phone. The long headset
cable lets you move freely, and the adjustable microphone boom
swings up and down so you can wear the headset over either ear.
Its features include:
Quick-Disconnect Plug — lets you disconnect the headset from
the dialer when you put a call on hold, 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 cord from pulling on the
headset.
Studio-Quality Electret Condenser Microphone — for clear voice
transmission.
Adjustable Volume — gives you full control of the volume level.
Touch-Tone or Pulse (Rotary) Dialing — letsyou use your ET-153
with either type of service.

specialized telephone services, such as Call Waiting.

button.
Belt Clip — lets you hook the phone’s remote keypad on your belt
for easy portability.

aids that have a T (telephone) switch.

Read This Before Installation
We have designed your ET-153 to conform to federal regulations
and you can connect it to most telephone lines. However, each de-
vice you connect to the phone line draws power from it. We refer to
this power draw as the device’s
ringer equivalence number
, or REN.
The REN is on the bottom of the ET-153.
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
a device from the line.
FCC Statement
Your ET-153 complies with Part 68 of
FCC Rules
. You must, upon
request, provide the FCC registration number and the REN to your
phone company. These numbers are marked on the bottom of the
ET-153.
Note: You must not connect the headset telephone to:
• coin-operated systems
• party-line systems
• most electronic key phone systems

Using Tone Services with a Pulse Line
Some special services, such as bank-by-phone, require tone sig-
nals. If you have pulse service, you can still use these special tone
services.
With TONE/PULSE set to PULSE,press at the point where tone sig-
nals are required. Any additional numbers you dial are sent as tone
signals. The phone automatically resets to PULSE dialing when you
hang up.

Troubleshooting
If the headset’s volume level drops or if the phone begins to make
unusual sounds, determine if other phones on the same line have
been picked up. In areas with low telephone voltage, the ET-153
might not operate when other phones are active on the same line.
Hanging up the other phones should correct the problem.
If you still have problems, immediately disconnect the ET-153. If oth-
er phones on the same line operate normally, the fault is in the ET-
153 or its installation. If you are unable to locate the problem, take
the ET-153 to your local RadioShack store for assistance.
