Precautions for installation

To prevent deformation or discoloration of the cabinet, do not install the unit where it is exposed to direct sunlight or high humidity, and avoid installation near air conditioning outlets.

Speaker vibrations may cause howling. Place the unit as far away from the player as possible.

Take the occurrence of earthquakes or other physical shocks into consideration when selecting the installation place, and secure the unit thoroughly.

This unit is magnetically shielded to avoid color distortions on TVs. However, if not installed properly, it may cause color distortions. So, pay attention to the following when installing the unit.

When placing this unit near a TV set, turn off the TV’s main power switch or unplug it before installing this unit.

Then wait at least 30 minutes before turning on the TV’s main

power switch again.

Some TVs may still be affected even though you have followed the above. If this happens, move this unit away from the TV.

Tuner reception may become noisy or hissing if this unit is installed nearby the tuner. In this case, leave a more distance between the tuner and this unit or use an outdoor antenna for better tuner reception without interference from this unit.

Precautions for Daily Use

To maintain the appearance of the unit

Wipe with a dry, soft cloth if the cabinet or control panel should become dirty.

If very dirty, apply a small amount of water or neutral detergent to the cloth and wipe clean. Then wipe with a dry cloth.

To improve the sound field

If the speakers are facing a solid wall or glass door, etc., it is recommended to furnish the wall with materials that absorb sounds, for example by hanging up thick curtains, to prevent reflections and standing waves.

Checking the Supplied Accessories

Check to be sure you have the following supplied accessories.

The number in parenthesis indicates the quantity of the piece supplied.

Monaural audio cord (1)

AC plug adaptor (1)

If the item mentioned above is missing, contact your dealer immediately.

When using Connecting Method Å, no signal comes out of the TO MAIN SPEAKERS terminal.

If your amplifier has only a monaural line output (MONO) jack, connect it to the LEFT/MONO jack of the INPUT 1 (LOW- LEVEL) terminal (see Connecting Method Å).

When you connect main (front) speakers to the TO MAIN SPEAKERS terminal, use the speakers within the impedance range indicated by the amplifier connected to the INPUT 2 (HIGH-LEVEL) terminal. If not, the amplifier connected to the INPUT 2 (HIGH- LEVEL) terminal may malfunction and be damaged.

DO NOT connect more than one speaker to one speaker terminal.
