Troubleshooting

Should problems occur, it is often unnecessary to consult your dealer or technical service department. On the basis of the following checks, you may be able to rectify a number of conditions yourself without difficulty. If the condition cannot be remedied after the following check, please consult your dealer.

The PMD620 does not turn on.

•Install fresh batteries.

•Check AC adapter connections.

The PMD620 turns on then turns itself off.

• Install fresh batteries.

The PMD620 seems to record, but there is no sound on playback.

•Check input settings.

(For example, if LINE input is selected and no input is connected to the LINE jack, the PMD620 will record silence. The PMD620 will not playback.)

There is no audio playback through headphones or internal speaker.

•Check VOL+/– control setting.

•Check a different audio file or the card.

The PMD620 will not record.

•Check that the maximum of 999 files have not been recorded.

•Check that the PMD620 acknowledges the card.

No signal from microphone input.

•Check input selection.

•Check REC LEVEL control settings.

•Check if microphone(s) require(s) Phantom power.

There is excessive noise on the PMD620.

•Check cable connections and/or replace cable.

•Check for proper gain levels.

Playback on a PC results in poor sound.

•Check quality of PC sound card and program.

•Check frequency conversion program.*

*The PMD620 records audio files with a sampling frequency of 48kHz. Some PC programs convert the files to 44.1kHz (using a sample rate converter). Only high quality sample rate converters should be used.

PC cannot read files

•Check the capability of the PC program. Some playback and editing programs do not support MP3 or Broadcast Wave (.wav) formats.

If the PMD620 exhibits erratic behavior, the microprocessor can be reset by powering off, disconnecting AC power and removing batteries.

Care and Maintenance

Use a soft cloth slightly moistened with mild detergent solution. Media cards that are heavily used should be occasionally reformatted to avoid audio problems due to fragmentation.
