CARE AND MAINTENANCE

Your RadioShack ET-893 Super Lightweight Headset Telephone is an example of superior design and craftsmanship. The following suggestions will help you care for the Headset Telephone so you can enjoy it for years.

Keep the headset and amplifier dry. If either gets wet, wipe it dry im- mediately. Liquids might contain minerals that can corrode the elec- tronic circuits.

Handle the headset and amplifier gently and carefully. Dropping them can damage circuit boards and cases and can cause the head- set to work improperly.

Use and store the Headset Telephone only in normal temperature environments. Temperature extremes can shorten the life of elec- tronic devices, damage batteries, and distort or melt plastic parts.

Keep the Headset Telephone away from dust and dirt, which can cause premature wear of parts.

Wipe the headset and amplifier with a damp cloth occasionally to keep them looking new. Do not use harsh chemicals, cleaning sol- vents, or strong detergents to clean them.

Modifying or tampering with the Headset Telephone’s internal components can cause a malfunction and might invalidate the ET-893’s warranty and void your FCC authori- zation to operate it. If the ET-893 is not operating as it should, take it to your local Ra- dioShack store for assistance. If the trouble is affecting the telephone lines, the phone company can ask you to disconnect your ET-893 until you have resolved the problem.

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 are in use. In areas with low telephone voltage, the ET-893 might not operate when other phones on the same line are in use. Hanging up the other phones should correct the problem.

If you still have problems, disconnect the ET-893. If other phones on the same line operate normally, the fault is in the ET-893 or its installation. If you are unable to lo- cate the problem, take the ET-893 to your local RadioShack store for assistance.
