My speaker system can't fully charge the Walkman or mobile phone
IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.
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. Manuals are posted on your model support page.
