PREPARATIONS (cont) pg. 5

REMOTE CONTROL

Inserting batteries

Detach the battery cover on the rear of the remote control and insert two size AA (R6) batteries.

When to replace the batteries

The maximum operational distance between the remote control and the sensor on the main unit should be
approximately 5 meters (16 feet). When this distance decreases, replace the batteries with new ones.

Using the remote control

The instructions in this manual refer mainly to the buttons on the main unit. Buttons on the remote control with the
same names as those on the main unit can be used as well.

To use FUNCTION on the remote control

The FUNCTION substitutes for the function buttons (TAPE, TUNER, VIDEO/AUX, CD, MD) on the main unit.
Each time FUNCTION is pressed while power is on, the next function is selected cyclically.

PLAY on the remote control

The function is the same as that of on the main unit.

• If the remote control is not going to be used for an extended period of time, remove the batteries to prevent possible
electrolyte leakage.

• The r emote control may not operate correctly when:

- The line of sight between the remote control and the remote sensor above DEMO/ECO is exposed to intense light,
such as direct sunlight

- Other remote controls are used nearby (those of a television, etc.)

BEFORE OPERATION

To turn the unit on

Press one of the function buttons (TAPE, TUNER, VIDEO/AUX, CD, MD). Playback of the inserted disc or tape
begins, or the previously tuned station is received (Direct Play Function).

POWER is also available.
To turn the power off

Press POWER. When the clock is set, the unit will return to the ECO mode or clock display depending on the
setting before you turn on the unit.
If the previous setting is DEMO, the unit will also return to the clock display.

• If the clock is not set, the unit will always return to the DEMO mode.

DEMO (Demonstration) mode

When the AC cord is connected, the display window demonstrates the functions of the unit. When the power is
turned on, the DEMO display is overridden by the operation display.

To cancel (Demonstration) mode

Press DEMO/ECO.
To re-activate the DEMO mode, press DEMO/ECO until the display window demonstrates the functions of the

unit.

To change the brightness of the display

Press DEMO/ECO twice during power on.
The display is dimmer than usual, press DEMO/ECO again to restore normal display.

Using the headphones

No sound is output from the speakers while the headphones are plugged in.

PREPARATIONS (cont) pg. 6

SETTING ECO (POWER ECONOMIZING) MODE

Setting this unit to power economizing mode reduces power consumption.
Press DEMO/ECO repeatedly (during power off) until "ECO MODE" is displayed.
The display disappears and the indicator beside the POWER lights up.

4-Channel Multi-Amplifier System

To provide reinforcement for the ultra-low frequencies, in addition to the Left/Right 2-channel amplifier used to
reproduce mid-to-high-range frequencies (200Hz - 20 kHz), this system incorporates a second L/R 2-channel
amplifier just for reproduction of ultra-low frequencies - making it, in effect, a 4-amplifier system. By utilizing
discrete amplifiers for mid-to-high-frequencies and low frequencies, high quality sonic reproduction that is virtually
free from distortion can be realized.
This Multi Amplifier System, which utilizes independent circuitry for the different frequency ranges, enables superb
sonic reproduction free from distortion.

Built-in Subwoofer System

The built-in subwoofer System has a separate subwoofer cavity area that is part of the loudspeaker cabinet structure,
which acts as a sonic filter to cut distortion components. (In the Multi Amplifier System, the ultra-low frequency
signals transmitted from their own independent amplifier are reproduced in this area.) This separate construction
gives a clear, rich definition to bass reproduction and it can realize clear, well-defined mid-to-high frequency signals.
And AIWA's built-in subwoofer system incorporates a subwoofer capable of powerful, satisfying bass performance

with true stereo separation.
