The LS423 is designed for sustained ambient temperatures between 0°C and 50°C, with transients up to 60°C (at 90% maximum relative humidity, non-condensing). Operating the player above 60°C ambient for prolonged periods may reduce the operational lifetime of the product.
The LS423 requires a power supply at 5V +/- 10%. If the LS423 is powered by the USB power adapter that it ships with, or by any USB port that identifies itself as a Dedicated Charging Port (DCP), it will provide up to 500mA of bus power to downstream devices on the USB Type-C port.
If the LS423 is powered by a USB port that does not identify itself as a DCP, it will limit available current of the USB Type-C port to 100mA to ensure that the total power drawn by the player does not exceed 1A.
