Zoom PD-01 manual Troubleshooting, No sound, Noise is heard

Troubleshooting

If there seems to be a problem with the unit, check the following points first.

No sound.

Are connections to the IN and OUT jacks reversed? Check the connections.

Is a battery inserted? If there is no battery in the unit and the AC adapter is not used, there will be no sound. Insert a fresh battery, or connect the AC adapter.

Is the guitar or amplifier volume or the LEVEL control of the PD-01 turned down? Raise the volume.

Are there any problems with other effect devices or with cables? Use a known good cable and connect the PD-01 directly to the amplifier.

Sound level is low, and sound is distorted also in bypass mode.

Is the battery exhausted? Insert a fresh battery.

Noise is heard.

Are several distortion effects used in series? Excessive compressor settings can also result in noise. Turn only the currently used devices on.

Is the cable of good quality? Low-quality cables can cause noise.

Is the unit used in the vicinity of a computer monitor, refrigerator, fluorescent lamp, motor, or similar device? The guitar or cable can pick up noise from such devices. In case of problems, increase the distance to such devices.
