Fault-Finding Charts
In this section, fault-finding charts are provided for the most common NPM-10 (3595)
errors.
Note: Since both D200 (UEM) and D400(UPP) are underfilled, they cannot be replaced. If either D200
or D400 is defective, the entire PWB has to be discarded.

Phone is Dead
This means that the phone does not draw any current at all when a supply is connected
and/or the power key is pressed. It is assumed that the voltage supplied is 3.6 VDC. The
UEM prevents any functionality whatsoever at battery/supply levels below 2.9 VDC.
