INSTALLATION  
WARNING: To reduce the risk of  
fire or shock hazard, do not ex-  
pose this product to rain or mois-  
ture.  
Each device that you connect to the  
phone line draws power from the phone  
line. We refer to this power draw as the  
device’s ringer equivalence number, or  
REN. The REN is shown on the bottom  
of the base.  
CAUTION  
RISK OF ELECTRIC SHOCK.  
!
DO NOT OPEN.  
CAUTION: TO REDUCE THE RISK OF  
ELECTRIC SHOCK, DO NOT REMOVE  
COVER OR BACK. NO USER-SERVICE-  
ABLE PARTS INSIDE. REFER SERVIC-  
ING TO QUALIFIED PERSONNEL.  
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 areas, a  
total REN of three might impair ringer  
operation. If ringer operation is impaired,  
remove a device from the line.  
This symbol is intended to alert you to  
the presence of uninsulated danger-  
ous voltage within the product’s enclo-  
sure that might be of sufficient  
magnitude to constitute a risk of elec-  
tric shock. Do not open the product’s  
case.

PREPARATION  
2. Put the batteries into the compart-  
ment as indicated by the polarity  
symbols (+ and –) marked inside.  
INSTALLING BATTERIES  
Your telephone uses two AAA batteries  
(not supplied) for power to retain the  
numbers you store in memory. For the  
best performance and longest life, we  
recommend alkaline batteries, such as  
Cat. No. 23-555.  
Cautions:  
• Always use fresh batteries of the  
required size and recommended  
type.  
3. Close the cover and tighten the  
screw.  
• Do not mix old and new batteries,  
different types of batteries (stan-  
dard, alkaline, or rechargeable), or  
rechargeable batteries of different  
capacities.  
4. Be sure the NORM/STORE BATT  
TEST switch on the back of the  
phone is set to NORM (see “Testing/  
Replacing the Batteries”).  
1. Use a Phillips screwdriver to loosen  
the screw in the battery compart-  
ment cover on the bottom of the  
telephone, then lift open the cover.  
Testing/Replacing the Batteries  
To test the batteries’ strength at any  
time, temporarily slide NORM/STORE  
BATT TEST (on the back of the tele-  
phone) to STORE BATT TEST.  
If the BATT TEST indicator does not  
light or is dim, replace the batteries.

43-637.fm Page 6 Friday, August 13, 1999 10:45 AM  
To prevent the loss of stored numbers  
when the batteries are removed, replace  
the batteries within 5 minutes.  
Placing the Phone on a  
Desk Top  
Set NORM/STORE BATT TEST back to  
NORM.  
SELECTING A LOCATION  
You can place the phone on a desk top  
or table, or mount it on a telephone wall  
plate or directly on the wall. Select a lo-  
cation that is:  
Plug one end of the supplied long modu-  
lar cord into the TEL LINE jack on the  
back of the phone. Then plug the other  
end into a modular phone line jack.  
• Near a telephone line jack  
• Out of the way of normal activities  
Mounting the Phone on a Wall  
• Near an AC outlet (only if you use  
an optional AC adapter; see “Con-  
necting an Optional AC Adapter” on  
Page 8)  
You can mount your telephone on a wall  
plate, or you can mount it directly on the  
wall using two screws (not supplied) with  
heads that fit into the keyhole slots on  
the bottom of the telephone.  
Notes:  
• Your telephone connects directly to  
a modular telephone line jack. If  
your phone line jack is not a modu-  
lar jack, you can update the wiring  
yourself, using jacks and adapters  
available at your local RadioShack  
store. Or, you can let the phone  
company update the wiring for you.  
If you are mounting the phone di-  
Note:  
rectly on the wall, drill two holes 315/16  
inches (100 mm) apart. Thread the two  
screws into the wall, letting the heads  
extend about 1/8 inch (3 mm).

You might prefer a longer cord for the  
handset. Your local RadioShack store  
has a wide selection of telephone acces-  
sories, including longer coiled handset  
cords.

jack on the back of the  
CONNECTING AN  
OPTIONAL AC ADAPTER  
Your telephone operates from telephone  
line power. In some areas, however, the  
telephone line might not provide enough  
power to operate all of your telephone’s  
features. If the speakerphone’s volume  
is too low, even with the volume control  
set to its highest setting, or if the speak-  
erphone does not work, connect an AC  
adapter (RadioShack Cat. No. 273-  
1454).  
2. Route the adapter cable through the  
strain relief slot on the bottom of the  
telephone.  
Strain Relief Slot  
Cautions:  
• The recommended adapter supplies  
6 volts DC, delivers at least 150 mil-  
liamps, and has a barrel plug which  
DC 6V  
properly fits the phone’s  
jack.  
Using an adapter that does not meet  
these specifications might damage  
the phone or the adapter.  
3. Plug the other end of the adapter in-  
to a standard AC outlet.  
To prevent damage to the adapter  
and the telephone, always plug the  
adapter into the telephone before  
you plug it into the AC outlet. Always  
unplug the AC adapter from the AC  
outlet first, then unplug the barrel  
plug from the phone.

TROUBLESHOOTING  
We do not expect you to have any problems with your phone, but if you do, the follow-  
ing suggestions might help.  
Problem  
Suggestion  
The phone does not work or  
works poorly.  
Be sure MODE is set properly.  
Ensure the phone line is properly connected.  
If you are using an optional AC adapter, ensure  
it is properly connected. See “Connecting an  
Optional AC Adapter” on Page 8.  
Memory does not hold pro-  
grammed numbers.

them.  
The telephone’s volume level  
drops or it begins to make  
strange sounds.  
Check to see if other phones on the same line  
have been picked up. This phone might not  
operate when other phones are active on the  
same line (especially in areas with low tele-  
phone voltage). Hang up the other phones.  
If you are using an optional AC adapter, ensure  
it is properly connected. See “Connecting an  
Optional AC Adapter” on Page 8.  
If you still have problems, disconnect the phone. If other phones on the same line work  
properly, the fault is in this phone or its installation. If you cannot find the problem, take  
your phone to your local RadioShack store for assistance.

CARE AND MAINTENANCE  
Your RadioShack ET-148 20-Number Memory Speakerphone with Privacy is an ex-  
ample of superior design and craftsmanship. The following suggestions will help you  
care for your phone so you can enjoy it for years.  
• Keep the phone dry. If it gets wet, wipe it dry immediately. Liquids might contain  
minerals that corrode electronic circuits.  
• Use and store the phone only in normal temperature environments. High temper-  
ature extremes can shorten the life of electronic devices, and distort or melt plas-  
tic parts.  
• Handle the phone gently and carefully. Dropping it can damage circuit boards  
and cases and can cause the phone to work improperly.  
• Keep the phone away from dust and dirt, which can cause premature wear of  
parts.  
• Wipe the phone with a damp cloth occasionally to keep it looking new. Do not use  
harsh chemicals, cleaning solvents, or strong detergents to clean your phone.  
Modifying or tampering with the telephone’s internal components can cause a mal-  
function and might invalidate your telephone’s warranty and void your FCC authoriza-  
tion to operate it. If your telephone is not performing as it should, take it to your local  
RadioShack store for assistance. If the trouble is harming the phone lines, the tele-  
phone company might ask you to disconnect your phone until you have resolved 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 compa-  
ny attempts to notify you in advance. If advance notice is not practical, the phone com-  
pany notifies you as soon as possible and advises you of your right to file a complaint  
with the FCC.  
Also, the phone company can make changes to its lines, equipment, operations, or  
procedures that could affect the operation of this telephone. The telephone company  
notifies you of these changes in advance, so you can take the necessary steps to pre-  
vent interruption of your telephone service.

LIGHTNING  
Your telephone has built-in protection circuits to reduce the risk of damage from surg-  
es 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 telephone.  
Lightning damage is not common. Nevertheless, if you live in an area that has fre-  
quent electrical storms, we suggest that you unplug your telephone during storms to  
reduce the possibility of damage.

OF THE POSSIBILITY OF SUCH DAMAGES.  
Some states do not allow the limitations on how long an implied warranty lasts or the exclusion of incidental or con-  
sequential damages, so the above limitations or exclusions may not apply to you.  
In the event of a product defect during the warranty period, take the product and the RadioShack sales receipt as

is made, become the property of RadioShack. New or reconditioned parts and products may be used in the perfor-  
mance of warranty service. Repaired or replaced parts and products are warranted for the remainder of the original  
warranty period. You will be charged for repair or replacement of the product made after the expiration of the war-  
ranty period.  
This warranty does not cover: (a) damage or failure caused by or attributable to acts of God, abuse, accident, mis-  
use, improper or abnormal usage, failure to follow instructions, improper installation or maintenance, alteration, light-  
ning or other incidence of excess voltage or current; (b) any repairs other than those provided by a RadioShack  
Authorized Service Facility; (c) consumables such as fuses or batteries; (d) cosmetic damage; (e) transportation,
