AC plug adaptor (1)

Use to adapt the plug on

the power cord to the

shape of the wall outlet.

(Accessory only for

regions where use is

necessary.)

Operation to reset

The microcomputer may fall into malfunction (impossibility to

operate, erroneous display, etc.) when the power cord is un-

plugged while power is ON or due to an external factor. In this

case, execute the following procedure to reset the microcom-

puter and return it to normal condition.

Set the POWER to OFF then, while holding down the REMOTE

POWER key, set the MAIN POWER key to ON.

•Please note that resetting the microcomputer clears the contents

stored in it and returns it to the condition when it left the factory.

CONTROLS

Main unit

About the standby indicator (KAF-3010R only)

This unit has a standby indicator that lights to show that a small amount of current is being supplied to the unit in order to preserve the

memory. This is called the Standby mode. When the Standby indicator is lit, the amplifier can be switched ON / STANDBY from the remote

control.

1POWER switch (KAF-3010R)

Usually leave this switch to the on position.

When the unit is not to be used for a long period of time, set

the switch to the OFF position for safety.

2ON/STANDBY key (KAF-3010R)

This key effective when the POWER key is set

to the on (standby) position, and pressing this key

turns power ON and off (standby).

3Standby indicator (KAF-3010R)

4POWER switch (KAF-1010)

5BASS knob

To adjust low frequencies.

6TREBLE knob

To adjust high frequencies.

7INPUT indicator

An indicator lights for the source selected

with the INPUT SELECTOR knob.

8VOLUME CONTROL knob

Adjust the volume.

9SOURCE DIRECT indicator

Usually leave this switch to the on (standby) position.

0SOURCE DIRECT key

To listen to a source with high quality sound.

!PHONES jack

Used for headphone listening.

@SPEAKERS A/B switches

Press to select the A and/or B speaker systems.

#BALANCE knob

Adjust the volume balance between left and right.

$INPUT SELECTOR knob

Turn to select the input sources.

%MUTING key/indicator
