-
If your Walkman is used in an environment where the temperature is below -5 °C (23 ºF), the battery life becomes shorter due to characteristics of the battery.
This is not a malfunction.
- Charge the battery until it is full.
- You can preserve the battery life and get more use from each charge by changing your Walkman settings and managing the power appropriately.
- Depending on the environment in which your Walkman is used, the battery may deteriorate if it is not used for over a year. Contact your nearest Sony dealer.
