N Getting started Unpacking Check that you have the following items before using the headphones:

• Rechargeable nickel-metal hydride batteries (2)

• The headphones MDR-IF540R (1)Getting started

Charging the supplied rechargeable batteries The supplied rechargeable nickel-metal hydride batteries are not charged from the first time you use them. Be sure to charge them before use. To charge the headphones, place them on the transmitter. 1 Press the button of the left housing to open the battery compartment lid. The battery compartment lid comes off. 2 Insert the supplied rechargeable nickel-metal hydride batteries into the battery compartment matching 3 terminal on the batteries to 3 in the compartment. Do not use rechargeable batteries other than the supplied ones. Button 3 Close the battery compartment lid. 4 If your AC power adaptor is equipped with a voltage selector, set it to the operating voltage in your area with a screw driver before connecting the AC power adaptor to an AC outlet.Getting started

5 Connect the supplied AC power adaptor to the transmitter. 6 Rest the headphones on the transmitter so that the headphones’ contact point meets the transmitter’s contact pin while making sure that the charging indicator lights up. The charging is completed in about 16 hours and the charging indicator goes off. When placing the headphones on the transmitter, be sure to hold them with both hands so that the right and left housings are horizontal. Place the headphones vertically on the transmitter then tilt them back as illustrated below. When the indicator is not lit Check if the right and left headphones are rested on the transmitter correctly. The indicator may not be lit if the headphones’ contact point does not meet the transmitter’s contact pin. Take off the headphones and place them on the transmitter again so that the indicator lights up. To recharge the headphone battery after use Place the headphones on the transmitter after you use the headphones. Since the built-in timer recognizes when charging is complete, there is no need to take off the headphones from the transmitter after the completion of charging. Notes

• The transmitter automatically turns off while charging the batteries.

• This system is designed to charge only the supplied rechargeable batteries type BP-HP550 for safety. Note that other types of rechargeable batteries cannot be charged with this system.

• If dry batteries are installed, they cannot be charged.

• Do not attempt to use the supplied BP- HP550 rechargeable batteries for other components. They are for use with this system only.

• Charge in an environmental temperature of between 0˚C and 40˚C (between 32˚F and 104˚F). AC poweradaptor(supplied)Transmitterto DC IN 9V jackto an AC outletRighthousingLeft housingGetting started

3 When connecting the transmitter to Playstation 2 Connect to INPUT B jack on the transmitter using the cable supplied with Playstation 2. 3 Connect the supplied AC power adaptor to the transmitter. Notes

• Do not connect to the INPUT A jack and INPUT B jack at the same time. If you connect two audio/visual components to both jacks at the same time, both of the audio signals may result in mixed output.

• Use only the supplied AC power adaptor. Do not use any AC power adaptor.

• When you connect the connecting cord directly to an earphone jack (monaural mini jack), the audio signal may not be output through the right channel. In such a case, use the separately sold PC-236MS plug adaptor (stereo mini jack h monaural mini plug) between the connecting cord and the earphone jack. Note Use the extension cord RK-C111 (sold separately) as necessary. 2 If your AC power adaptor is equipped with a voltage selector, set it to the operating voltage in your area with a screw driver before connecting the AC power adaptor to an AC outlet.

N Operating the system Listening to a programme Before listeningTo prevent your ears from beingdamaged, first lower the volume. 1 Turn on the audio/video component connected to the transmitter. When the audio signal is input, thetransmitter turns on automaticallyand the infrared emitters glow butthey do not glow while thetransmitter is charging the batteries.If the transmitter is connected to theheadphone jack, set the volumecontrol of the audio sourcecomponent as high as possible butnot so high that the audio signalbecomes distorted. 2 Put on the headphones. The power indicator on the upperpart of the right housing glows red.Be sure to put the right housing (R)on your right ear and the lefthousing (L) on your left ear. Wearthe headphones vertically on yourhead so that auto power on functionis properly activated. 3 Start playback of the component connected to the transmitter. 4 Adjust the volume. Notes•You may hear some noise when youdisconnect the AC power adaptor from thetransmitter before taking off theheadphones.•If the infrared sensors are covered by yourhands when adjusting the volume, themute function will be activated andvolume may not be adjusted. To adjust thevolume, move nearer toward thetransmitter or orient the infrared emitterson the left housing towards the transmitter.Operating the system

The headphones automatically turn off when they are taken off — Auto power on/off function Do not pull up the self-adjusting band when not in use, as this will consume the battery power. Sound is automatically muted if noise increases — Mute 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. To avoid potential ear damage as a result of noise, this function mute any sound from the headphones. Sound is automatically restored when you move nearer the transmitter or remove the obstruction. Using the vibration function Set the VIBRATION switch to ON and adjust the level of vibration using the vibration volume. You can enjoy powerful bass sound when you listen to movies or games through the headphones. Using SRS surround function Set the switch to ON to reproduce a wide surround sound field through the headphones. Using the ATT (Attenuator) switch If the input volume is low, set the ATT switch on the transmitter to OFF. If no audio signal is input for more than approximately 5 minutes The transmitter turns off automatically. Note The brightness of the infrared emitters may not be uniform, however, this is not a malfunction.Operating the system

The effective area of the transmitter The illustration below shows the approximate area covered by the infrared rays emitted from the transmitter. Notes•If you use the headphones at too great adistance from the transmitter, you mayhear a hissing noise and if there is an objectbetween the headphones and thetransmitter, sound may be interrupted.These phenomena are inherent to infraredray communication and do not mean thatthere is a problem with the system itself.•Do not cover the infrared sensors with yourhands or hair.•When you use the headphones inside thearea in the illustration above, thetransmitter can be placed in front, behindor by the side of you.•The noise you may hear through theheadphones may vary depending on thetransmitter position and room conditions.It is recommended that you place thetransmitter in a location that produces theclearest sound.•Do not use this system in areas exposed todirect sunlight or strong light. The soundmay be interrupted.•Plasma displays may interfere with normaloperation of this system.TransmitterInfrared rayApprox. 3 m(118
