(*1) Blinks at about
(*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 supplied USB cable 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 cable, the battery of your “WALKMAN” will not be charged. Instead, your “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 your “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 your “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 your “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 your “WALKMAN” after you have connected it to the computer for about 5 minutes.
