    How to use
    Effective area of the
    transmitter
    The illustration below shows the approximate area covered by
    the infrared rays emitted from the transmitter when you wear
    the headphones and face the transmitter.
    Transmitter

    Approx. 8 m
    (26 ft)
    Transmitter
    If you use the headphones at too great a distance from the
    transmitter, you may hear a hissing noise, and if there is an
    object between the headphones and the transmitter, sound
    may be interrupted. These phenomena are inherent in infrared
    ray communication and not a malfunction.
    Do not cover the infrared sensors with your hands or hair.
    When you use the headphones inside the area in the
    illustration above, the transmitter can be placed in front,
    behind or by the side of you. However, depending on
    circumstances, the area covered by the infrared rays may be
    smaller than illustrated.
    The noise you may hear through the headphones may vary
    depending on the transmitter position and room conditions. It
    is recommended that you place the transmitter in a location
    that produces the clearest sound.
    Do not use this system in areas exposed to direct sunlight or
    other strong light. The sound may be interrupted.
    Plasma displays may interfere with normal operation of this
    system.
    The brightness of the infrared emitters may not be uniform;
    however, this is not a malfunction.
    About muting function
    If the infrared rays are obstructed, or the headphones are used
    outside their effective range, noise will increase and sound will
    become hard to hear. In such a case, this function mutes any
    sound from the headphones to avoid potential ear damage as a
    result of noise. Sound is automatically restored when you move
    nearer the transmitter or remove the obstruction.
    Tips for charging
    Charge supplied battery first
    The supplied rechargeable nickel-metal hydride battery is not
    charged from the first time you use it. Be sure to charge them
    before use.
    About auto charge function
    Placing the headphones on the transmitter automatically turns
    them off, then charging starts. This eliminates the need for
    turning on/off every time you wear and take off the headphones.
    If CHG indicator is not lit
    Check if the right and left headphones are rested on the
    transmitter correctly. Take off the headphones and place them
    on the transmitter again so that the headphones’ contact points
    meet the transmitter’s contact pins.
    Charging and usage time
    Depending on the remaining battery status, it takes approx. 30
    minutes to 7 hours to recharge.
    Approx. charging time Approx. usage time
    1)
    7 hours
    2)
    28 hours
    3)
    1) at 1 kHz, 0.1 mW + 0.1 mW output
    2) hours required to fully charge an empty battery
    3) Time may vary, depending on the temperature or conditions
    of use.
    To recharge supplied battery after use
    Place the headphones on the transmitter after use. The CHG
    indicator lights up, then charging starts.
    When charging is complete, there is no need to remove the
    headphones from the transmitter.
    Remaining battery
    To check the remaining battery charge of the headphones, turn
    on the headphones, and check the POWER indicator. The battery
    is still serviceable when the indicator lights up red.
    Charge the headphones if the POWER indicator turns off, dims,
    flashes, or the sound becomes distorted or noisy.
    Notes
    Insert the AC adaptor plug firmly.
    Be sure to use the supplied AC adaptor. Using AC adaptors
    with different plug polarity or other characteristics can cause
    product failure.
    Unified
    polarity plug
    The battery capacity may decrease if the headphones are
    turned on and placed on the transmitter with the AC adaptor
    disconnected.
    The transmitter automatically turns off while charging the
    battery.
    This system is designed to charge only the supplied
    rechargeable battery BP-HP550-11 for safety. Note that other
    types of rechargeable battery cannot be charged with this
    system.
    If dry batteries are installed, they cannot be charged.
    Do not attempt to use the supplied rechargeable battery BP-
    HP550-11 for other components. It is for use with this system
    only.
    Charge in an environmental temperature of between 5 °C and
    35 °C (between 41 °F and 95 °F).
    When the battery life reduces to half, this may be the end of
    battery lifetime. The supplied rechargeable battery BP-HP550-
    11 is not commercially available. You can order the battery
    from the store where you purchased this system, or at your
    nearest Sony dealer.
    Using the headphones
    with separately-sold dry
    batteries
    Commercially available (size AAA) dry batteries can also be used
    to power the headphones. Install two batteries in the same
    manner as described in step 1 of “How to use.
    When dry batteries are installed, the battery charge function is
    not activated.
    Battery life

    50 hours
    2)
    1) at 1 kHz, 0.1 mW + 0.1 mW output
    2) Time may vary, depending on the temperature or conditions
    of use.
    Note
    Do not carry a dry battery together with coins or other metallic
    objects. It can generate heat if the positive and negative
    terminals of the battery are accidentally come into contact with
    metallic objects.
    Tips for connection
    Do not connect to the AUDIO IN 1 and AUDIO IN 2 jacks at the
    same time. If you connect two A/V components to both jacks
    at the same time, both of the audio signals may result in mixed
    output.
    When you connect the connecting cable directly to an
    earphone jack (monaural mini jack), the audio signal may not
    be output through the right channel.
    Tips for volume setting
    If you connect the transmitter to the headphone jack of the A/
    V component, set the volume of the A/V component as high as
    possible but not so high that the audio signal becomes
    distorted.
    When watching videos, be careful not to raise the volume too
    high in quiet scenes. You may hurt your ears when a loud
    scene is played.
    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 off.
    2 Place the new earpad
    around the housing.
    Troubleshooting
    If you run into any problems using this system, use the following
    checklist. Should any problem persist, consult your nearest Sony
    dealer.

    Loud background noise
    Use the headphones near the transmitter, or change the
    position of the transmitter. (As you move away from the
    transmitter, more noise is likely to be heard. This is inherent in
    infrared ray communication and not a malfunction.)
    Check that there is no object between the transmitter and the
    headphones.
    Check that the infrared sensors on the headphones are not
    covered with your hands or hair.
    If you use the headphones by a window where the sunlight is
    too strong, draw the curtains/blinds to shut out the direct
    sunlight, or use the headphones away from the sunlight.
    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.
    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.
    If you have another transmitter, check if more than one
    transmitters are used at the same time. Turn off other
    transmitter or move to a place outside the range of this
    transmitter.
    The sound cuts off
    The transmitter turns off if no signal or low signal is input for
    10 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.
    Battery cannot be charged/CHG
    indicator flashes, or does not light up
    Check that the right/left of the headphones and transmitter
    correspond, and put the headphones on the transmitter
    correctly.
    Install the supplied rechargeable nickel-metal hydride battery.
    Dry batteries and rechargeable batteries other than the
    supplied cannot be charged.
    If the CHG indicator does not light up even though you put the
    headphones on the transmitter and wait for a while, it may be
    the end of battery lifetime. You can order the supplied
    rechargeable battery BP-HP550-11 from the store where you
    purchased this system, or at your nearest Sony dealer.
    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
