Notes on charging the battery
The following are notes regarding charging.
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
Walkman for about 10 minutes, after which it should start operating normally again.
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 if you do not use your
Walkman for a long period of time.
Charging is not guaranteed with homebuilt or modified computers.
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 while charging. This is not a malfunction.
