The SA-Z1 Speaker System automatically turns off after 20 minutes of inactivity if the AUTO STANDBY setting is set to ON. If this occurs, a Walkman® or mobile phone connected to the USB port will stop charging.
To avoid this, set the AUTO STANDBY setting to OFF. For instructions, refer to the product manual.
