WALKMANNWZ-F886/F887

Notes on charging the battery

  • Charging time differs depending on battery usage conditions.
  • If the battery life is reduced to about half of its normal life even if sufficiently charged, it has probably worn out. Please contact your nearest Sony dealer.
  • If you charge your Walkman when it has not been used for a long period of time, your computer may not recognize it, or nothing may appear on the display.
  • Charge the battery in an ambient temperature of between 5 °C to 35 °C.
  • The number of times the battery can be recharged from complete discharge is approximately 500 times. This number may vary depending on the conditions under which you use your Walkman.
  • Charge the battery at least once every six months to a year even if you do not use your Walkman for a long period of time.
  • Charging is not guaranteed with homebuilt or modified computers.
  • Operation of a USB port extended with a USB hub is guaranteed only with a self-powered USB hub with an authorized logo.
  • Do not leave your Walkman connected for extended periods of time to a laptop computer that is not connected to AC power. Doing so may discharge the computer’s battery.
  • Do not turn on, restart, wake up from sleep mode, or shut down the computer with your Walkman connected to the computer by USB cable. Doing so may cause the Walkman to malfunction. Disconnect the Walkman from the computer before conducting those operations.
  • Heat may build up in your Walkman depending on the usage condition, such as while charging and/or an application is in use. This is not a malfunction.
  • The battery indicator scales are not equal. Refer the battery indicator as a guide.
