Troubleshooting Guide

• No power.

Cause

:

Power cord is disconnected.

Remedy: Connect power cord.

• Buzzing noise on AM, usually conspicuous at night or with a weak station.

(For models other than European models)

Cause

:

Noise from electrical apparatus such as fluorescent lamps.

Remedy: Move set to different location.
Remedy: Change the position or direction of the loop antenna.

• High pitch noise.

Cause: Noise from TV.

Remedy: Keep unit away from TV set.

• Crackling noise on AM and FM.

Cause: Noise caused by turning a fluorescent lamp on and off.

Remedy: Move the autenna as far away as possible from the fluores-

cent lamp.

Cause: Noise from automobile ignition.

Remedy: Install an outdoor FM antenna as far away as possible from

the road.

• AM stations cannot be received. (For models other than European models)

Cause: AM loop antenna is not attached.

Remedy: Connect the included AM loop antenna to the AM antenna

terminals.

• TUNED indicators and stereo indicator light but sound is distorted and

separation is bad.

Cause: Station is too strong.

Remedy: Change to T-shaped antenna.

Cause: Multiple reflection of the radio waves because of tall buildings or

mountains.

Remedy: Use antenna which has better directivity and select a point

with the least distortion.

• TUNED indicators and stereo indicator flicker and hiss is heard on FM.

Cause: Station is too weak.

Remedy: Install an outdoor FM antenna.
Remedy: Change the position or direction of the outdoor antenna.

Cause: Stereo FM broadcasts cover only about half the distance of an

ordinary broadcast.

Remedy: Switch to mono reception. (Even stereo broadcasts will be

heard in mono.)

• No station or undesired station is recalled.

Cause: The power cord has been unplugged for a long time.

Remedy: The memory contents are lost if the power is not turned on

and off a few times each month. Store all stations in the
memory again and remember to turn power on and off a few
times each month.

• The RDS function does not work.

Cause: The station is not an RDS station.

Remedy: Receive an RDS station.

Cause: The reception station signal is too weak.

Remedy: Install an outdoor FM antenna.
