Checking the battery charging status

While the battery is charging, the OPR lamp indicates the charging status of your Walkman. You can see the status of the OPR lamp through the OPR lamp window () on the USB cradle (supplied).
Lights up in red: Being charged
Turns off: Charged fully or not being charged. Your Walkman may consume battery power in this state. (*1)
(*1) If the computer enters a power saving mode such as the Sleep or Hibernation mode while your Walkman is connected via the USB cradle, the battery of the Walkman will not be charged. Instead, the Walkman continues to draw power from the battery, discharging it.
Hint
  • The procedure to cancel Sleep mode or Hibernation mode may vary depending on the computer. Please contact the manufacturer of your computer for details.

Checking the remaining battery power

Remaining battery power is indicated by the OPR lamp. When the OPR lamp color changes to red, recharge the battery.
(*1) Blinks at about 5-second intervals during playback and pause.
(*2) Blinks quickly with a long beep.
When the battery is depleted, the OPR lamp blinks red quickly and a long beep is heard. After that, you cannot operate your Walkman. See [Details] on battery duration.
Hint
  • When you turn off your Walkman, the OPR lamp turns off slowly by indicating the charging status.

Notes on charging the battery

  • The USB cradle (supplied) is not water resistant. Before charging the battery, make sure your Walkman is not wet. [Details]

  • Charge the battery in an ambient temperature of between 5 ºC (41 ºF) to 35 ºC (95 ºF). If you try to charge the battery in an ambient temperature outside this range, it will not properly charge. In such a case, the OPR lamp blinks red.

  • The number of times the battery can be recharged before it is used up is approximately 500 times. This number may vary depending on the conditions under which you use your Walkman.

  • The control buttons on your Walkman become inoperatable while connected to a computer.

  • To prevent battery deterioration, charge the battery at an interval of at least every six months to a year.

  • If the computer enters a power saving mode such as the Sleep or Hibernation mode while your Walkman is connected via the USB cradle, the battery of the Walkman will not be charged. Instead, the Walkman continues to draw power from the battery, discharging it.

  • Do not leave your Walkman connected for extended periods of time to a laptop computer that is not connected to AC power. Leaving the Walkman connected may discharge the computer’s battery.

  • Disconnect your Walkman from the computer before you turn on, restart, wake up from the sleep mode, or shut down the computer.

  • Heat may build up in your Walkman while charging. This is not a malfunction.

  • When you use your Walkman for the first time, or if you have not used the Walkman for a long time, recharge it fully (until the OPR lamp turns off).

  • When you use your Walkman for the first time, or if you have not used the Walkman for a long time, it may take a few minutes to be recognized by the computer, even if charging has already started (the OPR lamp lights up in red). Check that the computer recognizes the Walkman after you have connected it to the computer for about 5 minutes.
