Getting Started
The charging time differs depending on the 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 the Walkman may not respond. Charge the
Walkman for about 10 minutes, after which it should start operating normally
again.
Charge the battery in an ambient temperature between 5 °C to 35 °C (41 ºF to 95
ºF).
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.
