Model:               AVR4310CI


Subject:             The Net/USB function doesn't work properly.


Symptom: 1) The "Net/USB" function doesn't work properly at the first
production lot.
2) The unit indicates "Please Wait ... Connecting", and does not work.

Solution: We improved the sequence of the power stage.
MODIFICATION: Remove R52 (15k ohms Chip Resistor) located on the
"DM860 CORE MODULE".

Caution! :
1) Before you remove the chip resistor, attach masking tape to isolate R52.
2) Do not touch the hot soldering iron to chip capacitor (C37), because high
temperature will damage the chip capacitor.
3) Please use 0.5mm (0.02") thin solder and thin solder iron for this
modification.
