IMPORTANT SAFETY AND

OPERATIONAL INFORMATION

IMPORTANT SAFETY AND

OPERATIONAL INFORMATION

Please read the following safety and operational instructions before using the
C120 Wireless TV Amplifier. Keep these instructions for your reference.

When using your C120, these basic safety precautions and warnings should be
followed to reduce the risk of fire, electric shock, injury to persons and
damage to property.

WARNINGS

• If you or a member of your household has a pacemaker or other medical
device, consult your physician or the manufacturer of the pacemaker or medi
cal device before using this product. The product should be used in accor­dance with the guidelines provided by your physician or the manufacturer of
the pacemaker or medical device.

• Exposure to high volume sound levels may damage your hearing. Although
there is no single volume setting that is appropriate for everyone, you should
always use the headset with the volume set at moderate levels and avoid
prolonged exposure to high volume sound levels. The louder the volume, the
less time is required before your hearing could be affected. If you experience
hearing discomfort, you should stop using the headset. To protect your hear
ing, some hearing experts suggest that you:

1. Set the volume control in a low position before putting the headset on your
ears and then adjust the volume to a comfortable level.

2. Limit the amount of time you use the headset at high volume.

3. Avoid turning up the volume to block out noisy surroundings.

4. Turn the volume down if the sound from the headset prevents you from
hearing people speaking near you.

See www.plantronics.com/healthandsafety for more information on
headsets and hearing.

-

• CHILDREN. Never allow children to play with the product– small parts may
be a choking hazard and the amplified volume may cause hearing damage.

• To reduce the risk of electric shock, explosion or fire, only use the supplied
AC adapter. Do not disassemble the AC adapter as this may expose you to
dangerous voltages or other risks. Incorrect reassembly can cause electric
shock or fire when the product is subsequently used.

• Keep all products, cords, and cables away from operating machinery.

-

• Do not insert anything into the product because this may cause damage to
the internal components or cause injury to you.

• Avoid contact with liquids. Do not locate this product near water, for ex
ample, near a bathtub, or sink, in a wet basement, or near a swimming pool.

• Discontinue use of product and contact Clarity if the product overheats, has
a damaged cord or plug, if the product has been dropped or damaged, or if the
product has come into contact with liquids.

BATTERY WARNINGS

To reduce the risk of fire or injury to persons, read and follow
these instructions.

• Do not dispose of the product or battery in a fire. The battery cells may
explode. Check local laws for disposal instructions.

• Do not open or mutilate the battery. There may be corrosive materials
which can cause damage to eyes or skin and may be toxic if swallowed.

TROUBLESHOOTING

REGULATORY COMPLIANCE

If the C120HS is producing no sound:

1. Ensure that proper installation and setup procedures were followed
by reading the user guide carefully.

2. Check to see if all the equipment is turned on, including the
television, stereo or VCR.

3. Look over all the cord connections (power, audio from television
etc.), making sure none have become loose or disconnected.

4. Ensure that the line of sight from the C120 base to the headset
receiver is clear.

5. Check to see if the infrared sensor on the base is facing the
headset and make sure the headset sensor is facing the base.

6. If the microphone is being used, try either turning up the television
or repositioning the microphone.

7. The volume may be controlled by the television or the audio
outputs are turned off. Please refer to the television’s manual or
manufacturer for more information.

If the sound produced by the C120HS has static or is noisy:

1. If while in one mode (Stereo/Mono), static is experienced, switch
the base to the other mode.

2. Check the level of direct sunlight in the room. Too much direct
sunlight may cause interference.

3. Make sure the base is at the same height or above the level of the
headset when being worn.

4. Ensure the C120HS Headset battery is fully charged.

5. If you are trying to use the Away function at a public site, please
check with the site administration to make sure the service
is available.

Still Not Working?

If, after going through this checklist, the C120 is still not functioning
properly, call Clarity at 1-800-426-3738.
