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  
with either type of service.  
— lets you use your ET-153

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

aids that have a T (telephone) switch.

UL and FCC standards.

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  
ringer equivalence number  
this power draw as the device’s , 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  
FCC Rules  
. You must, upon  
Your ET-153 complies with Part 68 of  
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

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.

Care and Maintenance  
Your RadioShack ET-153 Super Lightweight Headset Telephone is  
an example of superior design and craftsmanship. The following  
suggestions will help you care for the ET-153 so you can enjoy it for  
years.  
Keep the ET-153 dry. If it gets wet, wipe it dry imme-  
diately. Liquids might contain minerals that can cor-  
rode the electronic circuits.  
Handle the ET-153 gently and carefully. Dropping it  
can damage circuit boards and cases and can  
cause the ET-153 to work improperly.  
Use and store the ET-153 only in normal tempera-  
ture environments. Temperature extremes can  
shorten the life of electronic devices and distort or  
melt plastic parts.  
Keep the ET-153 away from dust and dirt, which  
can cause premature wear of parts.  
21  
 
43-891B.fm Page 22 Thursday, February 18, 1999 3:46 PM  
Wipe the ET-153 with a damp cloth occasionally to  
keep it looking new. Do not use harsh chemicals,  
cleaning solvents, or strong detergents to clean the  
ET-153.  
Modifying or tampering with the ET-153’s internal components can  
cause a malfunction and might invalidate the ET-153’s warranty and  
void your FCC authorization to operate it. If the ET-153 is not oper-  
ating as it should, take it to your local RadioShack store for assis-  
tance. If the trouble is affecting the telephone lines, the phone  
company can ask you to disconnect your ET-153 until you have re-  
solved the problem.  
The FCC Wants You To Know  
In the unlikely event that your phone causes problems on the phone  
line, the phone company can temporarily discontinue your service.  
If this happens, the phone company attempts to notify you in ad-  
vance. If advance notice is not practical, the phone company notifies  
you as soon as possible and advises you of your right to file a com-  
plaint with the FCC.  
22  
 
43-891B.fm Page 23 Thursday, February 18, 1999 3:46 PM  
Also, the phone company can make changes to its lines, equipment,  
operations, or procedures that could affect the operation of this tele-  
phone. The telephone company notifies you of these changes in ad-  
vance, so you can take the necessary steps to prevent interruption  
of your telephone service.  
Lightning  
Your telephone has built-in protection circuits to reduce the risk of  
damage from surges in telephone line and power line current. These  
protection circuits meet or exceed the FCC requirements. However,  
lightning striking the telephone or power lines can damage your tele-  
phone.  
Lightning damage is not common. Nevertheless, if you live in an  
area that has severe electrical storms, we suggest that you unplug  
your phone during storms to reduce the possibility of damage.
