« ching the receptor. Adjust an angle of the transmitter (G). 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 soft 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.

Utilisation du système de haut-parleurs Réglez le commutateur POWER de l’amplificateur sur ON. L’alimentation du transmetteur est assurée par l’amplificateur. Lorsque vous mettez l’amplificateur sous tension, le transmetteur émet des rayons infrarouges et les récepteurs infrarouge des haut-parleurs (B) reçoivent les signaux. Lorsque les haut-parleurs reçoivent les signaux, le récepteur infrarouge s’allume en vert. Si le récepteur infrarouge s’allume en rouge, cela signifie que les signaux ne parviennent pas au récepteur. Réglage de l’angle du transmetteur (G). Remarques •Les rayons infrarouges ne traversent pas les murs ni le verre opaque. Par conséquent, le transmetteur doit être installé “en vue” des haut- parleurs sans fil... »
