Overview

The SA-IFT0 uses an infrared receptor to receive signals from the

transmitter so you can enjoy the maximum surround effect without an

excess of unsightly speaker cords.

When the wireless transmitter turns off or the infrared rays are

interrupted, the wireless speaker system stands by to save energy.

Precaution

On safety

•Should any solid object or liquid fall into the enclosures, unplug the

speaker system and have it checked by qualified personnel before

operating it any further.

On power sources

•The AC power cord must be changed only at a qualified service shop.

• Before operating the speakers, check that the operating voltage is

identical with your local power supply. The operating voltage is

indicated on the nameplate on the rear of the speakers.

• If you are not going to use the speakers for a long time, be sure to

disconnect the speakers from the wall outlet. To disconnect the AC

power cord, grasp the plug itself: never pull the cord.

On placement

•Do not place the speakers near heat sources, or in places subject to direct

sunlight, excessive dust or mechanical shock.

• Good ventilation is essential to prevent internal heat buildup. Place the

speakers in a location with adequate air circulation, and in a way that

does not block the rear ventilation holes.

•Placing the wireless speakers near a light bulb or in direct sunlight

may cause noise from the speakers.

On cleaning

• Clean the enclosures, panels and controls with a soft cloth slightly

moistened with a mild detergent solution, Do not use any type of

abrasive pad, scouring powder or solvent such as alcohol or benzine.

If you have any question or problem concerning your wireless

speakers, please consult your nearest Sony dealer.

Unpacking

•WIRELESS SPEAKER SYSTEM SA-IFTOS (2)

•WIRELESS TRANSMITTER EMT-?0 (1)

Hookups

Connecting the infrared transmitter to the WIRELESS REAR SPEAKER

jack on the amplifier (_).

Note

If your amplifier does not have a wireless rear speaker jack, use the

input adaptor IAD-IFT0 (not supplied) for connection.

Connecting the AC power cord of the speaker to a wall outlet (_]).

Setting up the speaker system

Place the L - speaker to the left and the R - speaker to the right.

Place the wireless speakers facin.__each other about 1 m (2 to 3 feet)

above your listening position ([._).

The approximate effective area of the infrared ray emitted from the

transmitter is l0 m (30 feet) (['_l). Adjust the position, direction and angle of

the transmitter so the wireless speakers (STANDBY (red) indicator and

infrared receptor) are within the effective area.

You can place the transmitter on top of the TV, an other component ([=-I).

or hang it on a wall (r_).

Using the speaker system

Set the amplifier's POWER switch to ON.

The power for the transmitter is supplied by the amplifier. When you turn

on the amplifier's power, the transmitter starts emitting infrared rays and

the infrared receptors on the speakers (r_ll) receive the signals. When the

speakers receive signals, the infrared receptor lights up green. If the

infrared receptor lights up red, the signal is not reaching the receptor.

Adjust an angle of the transmitter (V_l).

Notes

• The infrared ray will not penetrate walls or opaque glass.

Therefore, the transmitter must be placed "in sight" of the wireless

speakers.

• Placing the transmitter too far away from the wireless speakers

may cause noise.

• Do not block the path between the wireless speakers and the transmitter.

Otherwise, the speakers will be noisy and then enter stand by mode.

•When you are using other appliances that emit infrared rays at the same

time, may be happen of the jamming, do not use at the same time,

• Use the transmitter only, for keep off the jamming.

• If the sound from the speakers is very soR or not clear, turn the wireless

speakers towards the transmitter.

• When you are using the speaker system for long time, the surface of the

transmitter getting hot but no damage for the unit.

• If you experience noise from the wireless speaker while the transmitter is

disconnected, turn off the power of the input adaptor or amplifier before

disconnecting the plug.

Troubleshooting

No sound or only a very low sound level is heard from the

speakers,

• Make sure the transmitter is securely connected to the amplifier.

• The surround sound is turned off.

• Adjust the volume of the Wireless rear speakers (on the amplifier).

• Check the sound image balance with the TEST TONE feature (on the

amplifier},

• The infrared transmitter is too far from, or not aimed at the Wireless

speaker.

• Remove any obstructions between the transmitter and the Wireless

speakers.
