In thiscase, 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 REMOTEPOWER key, set the MAIN POWER key to ON.Please note that resetting the microcomputer clears the contentsstored in it and returns it to the condition when it left the factory.KAF-1010(K) 1P 98.4.25 3:57 PM yW 3RadioFans.CN 收音机爱 好者资料库KAF-1010/3010R3CONTROLSMain unitAbout 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 thememory. This is called the Standby mode. When the Standby indicator is lit, the amplifier can be switched ON / STANDBY from the remotecontrol.1 POWER 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, setthe switch to the OFF position for safety.2 ON/STANDBY key (KAF-3010R)This key effective when the POWER key is setto the on (standby) position, and pressing this keyturns power ON and off (standby).3 Standby indicator (KAF-3010R)4 POWER switch (KAF-1010)5 BASS knobTo adjust low frequencies.6 TREBLE knobTo adjust high frequencies.7 INPUT indicatorAn indicator lights for the source selectedwith the INPUT SELECTOR knob.8 VOLUME CONTROL knobAdjust the volume.9 SOURCE DIRECT indicatorUsually leave this switch to the on (standby) position.0 SOURCE DIRECT keyTo listen to a source with high quality sound.!
