Motorola MF-P01 owner manual Troubleshooting, Specifications

Tracing faults in a recording setup is often a mixture of logical deduction and patience. Very often, the problem is caused by something simple; a cable which hasn’t been plugged in properly, or a faulty cable. If you discover a faulty cable, replace it with a new one - it’s not worth hanging onto bad cables!

The MF-P01’s POWER light does not come on.

Is the PS-P2 adaptor plugged into the power supply? Is the PS-P2 adaptor plugged into the MF-P01?

Is the POWER switch on the MF-P01 set to ON?

The tape does not move when the PLAY button is pressed.

Is the tape properly inserted in the MF-P01? Is the tape at the end of the tape?

Some tracks have been recorded on the tape, but nothing can be heard when playing back.

If you’ve just put in a tape you recorded in another session, make sure that it’s the right way round. Make sure the LEVEL and MASTER controls are set appropriately (not to "0").

If you can hear something through the headphones but cannot from the speakers, check the LINE OUT connections and make sure the amplifier is set to the correct input source.

Troubleshooting

Nothing appears on the meter indicators when a source is played.

Is the source (microphone, guitar, etc.) switched on and volume control turned up? If it uses batteries, does it need new batteries?

Is the INPUT LEVEL control of the channel set appropriately (not to "0")?

Cannot press the RECORD key.

Is the tape properly inserted in the MF-P01? Is the tape record-protected?

The RECORD key is pressed, the tape moves, but nothing is recorded, or the level is very low.

Is one of the REC FUNCTION switches depressed? Check the LEVEL control for the track.

Is the INPUT LEVEL control set correctly? Is the recording level is too low or too high?

Tape sounds are muffled on playback.

The heads are dirty. Clean them (see "Cleaning the heads").

The mixdown signal is noisy or distorted.

Is the recording level is too low?

Is the PHONES plug is connected during mixdown?
