TH-205/215 Protection Fuse Replacement                 7-22-87


When a plug other than the PG-2V or PG-3C is inserted into the DC IN jack,
the ground side of the jack may not disconnect.  This may cause the
external DC power to be supplied directly to the internal battery which
results in overheating the battery and blowing the fuse.  To protect the
battery, replace the fuse with a protection diode, part number ERB83-004.

Note models with serial numbers greater than 801XXXX allready incorporate
this diode as D16.
