Tips for better reception
Receiving performance
This system utilizes very high frequency signals in the 900
MHz band so the receiving performance may deteriorate
due to the surroundings. The following examples illustrate
conditions that may reduce the reception range or cause
interference.
– Inside a building with walls containing steel beams
– An area with many steel file cabinets, etc.
– An area with many electrical appliances capable of
generating electromagnetic fields
– The transmitter is placed on a metal instrument.
– An area facing a roadway
– Noise or interfering signals exist in the surroundings due
to radio transceivers in trucks, etc.
– Noise or interfering signals exist in the surroundings
owing to wireless communication systems installed
along roadways.
Effective area of the transmitter
The optimum distance is up to approximately 45 m (150 ft)
without the system picking up some interference.
However, the distance may vary depending on the
surroundings and environment.
– If the system picks up some noise within the above
mentioned distance, reduce the distance between the
transmitter and the headphones, or select another
channel.
– When you use the headphones inside the effective area
of the transmitter, the transmitter can be placed in any
direction from the listener.
– Even within the signal reception area, there are some
spots (dead spots) where the RF signal cannot be
received. This characteristic is inherent to RF signals, and
does not indicate malfunction. By slightly moving the
transmitter, location of the dead spot can be changed.
Replacing the earpads
The earpads are replaceable. If the earpads become dirty
or worn out, replace them as illustrated below. The
earpads are not commercially available. You can order
replacements from the store where you purchased this
system, or at your nearest Sony dealer.
1 Remove the old earpad by pulling it out of the groove
on the housing.
2 Fit the new earpad in the groove of the housing.
Make sure the earpad is set to the vertical position.
Precautions
– When this system is not to be used for a long period of
time, disconnect the AC adaptor from the AC outlet
holding the plug, and remove the battery from the
headphones to avoid damage caused by battery
leakage and subsequent corrosion.
– Do not leave this system in a location subject to direct
sunlight, heat or moisture.
– You may hear some noise when you disconnect the AC
adaptor from the transmitter before taking off the
headphones.
– Avoid exposure to temperature extremes, direct sunlight,
moisture, sand, dust or mechanical shock.
– Please note that water does not splash, this product is
not waterproof specification.
Notes on headphones
To reduce the risk of 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.
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
your nearest Sony dealer.
Be sure to bring the headphones and the transmitter to
the Sony dealer when requiring repair work.
Troubleshooting
If you run into any problems using this system, use the
following checklist. Should any problem persist, consult
your nearest Sony dealer.
No sound/Low sound
– Check the connection of the A/V component or the AC
adaptor.
– Check that the A/V component is turned on.
– If you connect the transmitter to an A/V component
using the headphone jack, raise the volume level on the
connected A/V component within the range where the
sound is not distorted.
– Change the radio frequency with the CHANNEL selector
on the transmitter, then change the radio frequency to
that of the transmitter with the AUTO TUNING button on
the headphones.
– Use the headphones near the transmitter, or change the
position of the transmitter.
– Charge the supplied rechargeable battery, or replace dry
batteries with new ones. If the POWER indicator is still
off after charging, take the headphones to a Sony dealer.
– Raise the headphone volume.
If you cannot receive a clear audio signal
First change the radio frequency with the CHANNEL selector switch on the
transmitter, then briefly press the AUTO TUNING button on the headphones.
Noise Reduction process
The transmitter compresses the audio signal and converts it to RF signal. The
headphones convert the received RF signal to an audio signal and decompresses it. This
process reduces noise picked up during transmission.
The transmitter compresses the audio signals dynamic range, then converts it to RF
signal.
Noise may occur due to long distance transmission, etc.
The headphones convert the RF signal to an audio signal.
Noise may occur during conversion.
Decompression of the audio signals dynamic range reduces the noise level and
improves the S/N (signal-to-noise) ratio.
The sound cuts off
– The transmitter turns off if no signal or low signal is
input for 4 minutes. If you connect the transmitter to an
A/V component using the headphone jack, raise the
volume level on the connected A/V component within
the range where the sound is not distorted.
Distorted or intermittent sound
(sometimes with noise)
– Use the headphones near the transmitter, or change the
position of the transmitter.
– Do not place the transmitter on a metallic table.
– If you connect the transmitter to an A/V component
using the headphone jack, lower the volume level on the
connected A/V component within the range where the
sound is not distorted.
– Change the radio frequency with the CHANNEL selector
on the transmitter, then change the radio frequency to
that of the transmitter with the AUTO TUNING button on
the headphones.
– Charge the supplied rechargeable battery, or replace dry
batteries with new ones. If the POWER indicator is still
off after charging, take the headphones to a Sony dealer.
Loud background noise
– If you connect the transmitter to an A/V component
using the headphone jack, raise the volume level on the
connected A/V component within the range where the
sound is not distorted.
