PREPARATION

CONNECTING THE CD CHANGER

Follow these steps to connect the CD changer to your audio system and to power.

CD Changer

Receiver/Amplifier

1.Select a location for your CD changer that is near your receiver/ amplifier and a standard AC outlet.

Caution: Do not place the CD changer on top of the receiver/amplifier or any other component that gets hot.

Note: If you place the CD changer near other audio components or their wires, you might hear a hum when you play a CD. To eliminate the hum, move the components or their wires.

2.Plug one end of the supplied audio cable into the CD changer’s LINE OUT L (left) andR (right) output jacks, matching the red plug to the redR jack and the white plug to the whiteL jack.

3.Plug the other end of the cable into the receiver/amplifier’s left and right CD, AUX, or TAPE input jacks.

Caution: Do not use the receiver/ amplifier’s PHONO inputs. Doing so could damage the receiver/amplifier.

4.Plug the CD changer’s power cord into a standard AC outlet.

USING THE REMOTE CONTROL

Installing Batteries

Your CD changer’s remote control requires two AA batteries (not supplied) for power. We recommend alkaline batteries, such as RadioShack Cat. No. 23-552,for the best performance and longest life.

Cautions:

Always use fresh batteries of the required size and recommended type.

Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

1.Press down on the battery compartment cover and slide it off.

2.Install the batteries in the compartment as indicated by the polarity symbols (+ and –)marked inside.

illustration

3. Replace the cover.

You can use the remote control up to a distance of about 20 feet. If the remote control operates erratically or does not work, replace both batteries.

Cautions:

Never leave dead or weak batteries in the remote control. Batteries can leak chemicals that can corrode the control.

If you will not be using the remote control for a month or more, remove the batteries.

Using the Remote

You can use the remote control for any of the CD changer’s functions except turning power on/off and opening/ closing the CD compartment.

For the best results, point the remote control toward REMOTE SENSOR on the front of the CD changer.
