  • If the HOLD switch is set to the HOLD position, slide the switch to the opposite position.
  • If your Walkman contains moisture condensation, wait a few hours to let the Walkman dry out.
  • If the remaining battery power is low or insufficient, charge the battery.
  • You cannot operate your Walkman while it is connected to a computer. Disconnect the Walkman from the computer.
  • If your Walkman still does not operate after charging the battery, press the RESET button with a pen or a paper clip, etc., to reset the Walkman.
