TROUBLESHOOTING

If you encounter what appears to be a malfunction,

please check the following points before assuming that
your PDP-300 is faulty.

1. No Sound When the Power is Turned ON

Is the AC plug properly connected to an AC wall out-
let? Check the AC connection carefully. Is the VOL-
UME control turned up to a reasonable listening
level?

2. The PDP-300 Reproduces Radio or TV Sound

This can occur if there is a high-power transmitter in
your vicinity. Contact your Yamaha dealer.

3. Intermittent Static Noise

This is usually due to turning ON or OFF a household
appliance or other electronic equipment which is fed
by the same AC mains line as your PDP-300.

4. Interference Appears On Radio or TV Sets Located

Near the PDP-300
The PDP-300 contains digital circuitry which can gen-
erate radio-frequency noise. The solution is to move
the PDP-300 further away from the affected equip-
ment, or vice versa.

5. Distorted Sound When the PDP-300 is Connected

to An External Amplifier/Speaker System
If the PDP-300 is connected to a stereo system or in-
strument amplifier and the sound is distorted, reduce
the setting of the PDP-300 volume control to a level at
which the distortion ceases.
