Sony M-427 Leaflet

Thank you for purchasing the Sony Microcassette-

Corder. Some features are:
•The  BATT lamp indicates when to replace the batteries.
•The VOR (Voice Operated Recording) system (M-529V/

539V/579V only) starts and stops recording
automatically in response to the sound.

•Edit function—You can start recording directly from the

playback mode by pressing the r button to correct a
previously recorded portion.

•Tape counter (M-529V/539V/579V only)
•Automatic shut-off mechanism at the end of the tape (in

the recording/playback mode only)

•Stop-pause-release function—The pause switch is

released automatically when the p6 button is
depressed, so that you don’t miss a recording chance.

To clean the tape head and path
Press 9 and wipe the head, capstan and the pinch roller
with a cotton swab, moistened with alcohol every 10
hours of use.

To clean the exterior
Use a soft cloth slightly moistened in water. Do not use
