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 pro blems, immediately disconnect the ET -153. If other phones on the same line operate normally, the fault is in the ET153 or its installation. If you are unable to locate the problem, take
the ET-153 to your local RadioShack store for assistance.

Care and Mainte na nc e
Your RadioShack ET-153 Super Lightweight Headset Telephone is
an example of superior design and craftsmanship. The following
suggestions will he lp y ou c are for the ET-153 so y ou c an en jo y it for
years.
Keep the ET-153 dry . If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits.
Handle the ET-153 ge ntly and c aref ull y. 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 temperature 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 loo king new. Do not use harsh chemic als,
cleaning solvents , or s trong deterge nts to c lean the
ET-153.
Modifying or tampering with the ET-153’s internal components can
cause a malfunction and m ight invalidate the ET-153’s warra nty and
void your FCC authorization to operate it. If the ET-153 is not operating as it should, take it to your local RadioShack store for assistance. If the trouble is affecting the telephone lines, the phone
company can ask you to disconnect your ET-153 until you have resolved the problem.
The FCC Wants You To Know
In the unlikely eve nt that your phone caus es problems on the phone
line, the phone company can temporarily discontinue your service.
If this happens, the phone company attempts to notify you in advance. If advance n otice is not practical , the phone compan y notifies
you as soon as possib le a nd ad vi ses you of your right to file a c om plaint with the FCC.
22
43-891B.fm Page 23 Thursday, February 18, 1999 3:46 PM
Also, the phone compan y can make c hanges to its l ines, equipm ent,
operations, or procedures that could affect the operation of this telephone. The telepho ne compa ny notifie s you of t hese chan ges 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 l ine and power line current. These
protection circuits meet or exceed the FCC requirements. How ev er,
lightning striki ng the teleph one or pow er lines can damage yo ur telephone.
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.
