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.

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

out to loosen it.
3. Holding the headset in place
(as shown), adjust the micro-

even with your chin. Experi-
ment until you find the most
