PREPARATION

CONNECTING TO AN AUDIO SOURCE

Caution: Do not connect the transmitter to the audio source's speaker output. Doing so could damage the transmitter and audio source.

Connect the transmitter to your audio source's stereo headphone jack or to separate left and right audio output jacks (if available). If you connect the transmit- ter to audio output jacks, you can use the headphones’ volume control to ad- just the volume without turning up the volume on your audio source.

To connect the transmitter to your audio source's stereo headphone jack, plug the single (1/8-inch) end of the supplied Y adapter cable into the headphone jack and connect the other ends into the sup- plied stereo audio cable (red plug to red jack and white plug to white jack). Then connect the red plug to transmitter's R/ AUDIO IN jack and connect the white plug to the L/AUDIO IN jack.

Note: To connect a Y-adapter to a 1/4- inch headphone jack, slip the supplied

1/4-inch adapter plug over the 1/8-inch plug and complete the connections.

To connect the transmitter to your audio source's audio output jacks, connect one end of the supplied stereo audio ca- ble to the transmitter's R/AUDIO IN and R/AUDIO IN jacks (red plug to R/AUDIO IN and white plug to L/AUDIO IN). Then plug the other ends into the audio source's audio output jacks (red plug to the right channel and white plug to the left channel).

USING AC POWER

Use the supplied 12-volt, 100-mA AC adapter to connect the transmitter to AC power.
