Precautions; Troubleshooting - Sony MDR-IF140K Operating Instructions Manual

Precautions

• When the transmitter is not to be
used for a long period of time,
disconnect the AC power adaptor
from the AC outlet holding the plug
and remove the battery to avoid
damage caused by battery leakage
and subsequent corrosion.
• Do not leave the cordless stereo
headphones system in a location
subject to direct sunlight, heat or
moisture. (It is recommended to use
the headphones at a temperature of
between 5˚C and 35˚C (between 41˚F
and 104˚F).)
• Do not drop, hit or otherwise subject
the transmitter or headphones to
strong shocks of any kind. This could
damage the product.
Notes on headphones
preventing hearing damage
• Avoid using headphones at high
volume. Hearing experts advise
against continuous, loud and
extended play. If you experience a
ringing in your ears, lower the
volume or discontinue use.
• Excessive sound pressure from
headphones can cause hearing loss.
Caring for others
Keep the volume at a moderate level.
This will allow you to hear outside
sounds and to be considerate to the
people around you.
If you have any questions or problems
concerning the system that are not
covered in this manual, please consult
nearest Sony dealer.
Be sure to bring the headphones and
the transmitter to Sony dealer when
requiring repair work.
