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

3

43-891B.fm Page 4 Thursday, February 18, 1999 3:46 PM

Hold Button — lets you put a call on hold.

Flash — sends a timed electronic switchhook signal for use with specialized telephone services, such as Call Waiting.

Ringer OFF/ON — lets you turn the ringer on or off.

Redial — lets you redial the last number dialed with the touch of a button.

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

Hearing-Aid Compatible — lets you use the ET-153 with hearing aids that have a T (telephone) switch.

The ET-153 has been tested and found to comply with all applicable

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 device 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

43-891B.fm Page 20 Thursday, February 18, 1999 3:46 PM

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 other 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 immediately. Liquids might contain minerals that can corrode 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 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 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 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 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 advance. If advance notice is not practical, the phone company notifies you as soon as possible and advises you of your right to file a complaint 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 telephone. The telephone company notifies you of these changes in advance, 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 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.
