The HO523 is designed for sustained ambient temperatures between 0°C and 50°C, with transients up to 70°C (at 90% maximum relative humidity, non-condensing). Operating the player above 50°C ambient for prolonged periods may reduce the operational lifetime of the product.
Exposing a cold player to warm air at high relative humidity may cause water to condense inside the player, leading to component failure. Damage due to such internal condensation is not covered by warranty. If a player is cold, allow several hours for it to acclimatize to ambient conditions before applying power.
The power supply for the HO523 is rated at 19W (19V@1A). The device will use less than 11W of power when playing a 1920x1080x60p H.265 (HEVC) source file.
An additional 8W of power is available for peripherals connected to the player. This is sufficient to provide up to 1A at 5V on the USB 2.0 port and up to 0.5A at 3.3V on the GPIO 3.3V pin.
