Haier LE55B7500U Service Manual page 19

Remarks:
1. USB interface of digital multimedia player is not all-purpose. So when some USB devices could not be recognized,
the problem is usually not the performance failure but due to device driver.
2. Because USB devices and memory capability are different, the time needs for multimedia player to read
information are also different. So the information reading speed of the player temporarily getting slow are not the
performance failure.
3. The voltage supplied to USB interface is 5V, and the most electrical current is 500mA. When some interface
criteria ofUSB devices are different from standard USB protocol, digital multimedia player may be unable to
recognize USB devices correctly, which is normal status.
4. USB could be used as an interface to update software.
5. If some files source could not play because of the parameter decoding-limitation, the problem is not performance
failure
