Trouble and repair
When you experience one of phenomena described below, chances are
that the trouble may easily be righted. So we suggest that you check
connections and operating procedures again.
If no sound comes from speakers:
* Are the cartridge, turntable, amplifier, speakers, etc. correctly
connected ?
Are ali the controls on the amplifier, input selector switch, tape
monitor switch, speaker selection switch, etc. turned to the correct
position?
If no sound comes from one of speakers:
* Are the cartridge, turntable, amplifier, speakers, etc. correctly
connected?
Is the balance control on the amplifier set at a center or near-center
position?
*
If reproduction quality is poor:
Is the turntable truly horizontal?
Is the turntable placed atop a speaker system? (It should not be.
Refer to the section titled ‘‘Howling’’ in this brochure.)
Are the stylus tip and the record free of dirt and dust?
Is the correct tracking force applied? How about antiskating adjust-
ment?
*
If booming hum is audible:
Is the unit’s grounding cable correctly connected to the amp’s GND
terminal?
ls the cartridge correctly connected?
Are there electric appliances in operation near the unit? (There
should not be. Refer to ‘Induced hum" in this brochure.)
