Troubleshooting Guide

Before requesting service for this unit, check the chart below for a possible cause of the problem you are experiencing. Some simple checks or a minor adjustment on your part may eliminate the problem and restore proper operation.

If you are in doubt about some of the check points, or if the remedies indicated in the chart do not solve the problem, refer to the directory of Authorized Service Centers (enclosed with this unit) to locate a convenient service center, or consult your Technics dealer for instructions.

Problem	Probable cause(s)	Suggested remedy
While listening to FM broadcasts
An unusual hissing noise is heard when listening to the broadcast in stereo, but not heard when listening monaurally.	Due to the differences between a monaural and a stereo signal, a higher level of signal strength is required for proper stereo reception. If the signal level is low, a hissing noise may be produced on the stereo channel.	Try reducing the treble sound by using the treble control of the amplifier.Set for monaural reception to reduce the hiss. Note, however, that the broadcast will not be heard as stereo.Try changing the location, height and/or direction of the antenna.If an indoor antenna is being used, change to an outdoor antenna.Try using an antenna with more elements.
Noise is excessive in both stereo and monaural broadcasts.	Poor location and/or direction of the antenna.Transmitting station is too far away.
The FM stereo indicator or the quartz lock indicator flickers, without completely illuminating.	Poor location and/or direction of the antenna.Transmitting station is too far away.	Try changing the location, height and/or direction of the antenna.If an indoor antenna is being used, change to an outdoor antenna.Try using an antenna with more elements.
Excessive distortion in the sound of stereo broadcasts.	Nearby building or mountain.[Multipath distortion is being caused by the mutual interference of broadcast signals received directly from the transmitting station (direct waves) and signals being reflected from nearby buildings or mountains (reflected waves).]
Sound is distorted, "popping" noise is heard, and/or the volume level becomes low.	Broadcast signals are being disturbed by nearby automobile traffic or airplanes.	Relocate the antenna and the connection wires to a place farther away from where automobiles pass.

While listening to AM broadcasts

An unusual “beat” sound is heard.	Unit is being used at the same time as the television set.	Switch OFF the television set, or use this unit farther away from it.
A low-pitched “hum” sound is heard when the broadcast is tuned.	The AM loop antenna connection wires are too close to the power cord.	Place the antenna connection wires and the power cord farther apart.
	The power supply frequency from the power cord is modulated and heard from the speakers.	Install a special outdoor antenna.
A strange hissing noise is produced continuously or intermittently.	Caused by the “discharge phenomenon” and the “oscillation phenomenon” of electric appliances (such as fluorescent lights, TV, small series-type motors, rectification equipment, etc.)	Try placing this unit farther away from such equipment.Install noise-prevention equipment on this unit or on the electric appliance.

While using the remote-control transmitter

The remote-control transmitter does not function.	Batteries are incorrectly placed.	• Insert the batteries so that the positive (+) and negative (−) polarities are correct.
	The remote-control transmitter batteries are consumed.	• Replace them with new batteries.
	There is an obstruction between the remote-control transmitter and this unit.	• Remove the obstruction.
	The remote-control transmitter is not correctly facing this unit.	• Face the remote-control transmitter correctly toward this unit.
