SOFTWARE UPGRADING & SPECIAL KEY CONTROL
1. Software Upgrading
a) Burn the software "bank30.rom" in CD-R/CD-RW (lower burning speed is recommended).
b) Load CD-R/CD-RW in DVD receiver.
c) After finished loading, VFD will show "Read" and OSD will display "Reading".
d) After reading, system will start upgrading software, VFD will show "Update" and OSD will
display "Erase" then "Writing".
* If fail to upgrade, OSD will display "Checksum error". Turn off/on power and try upgrading
again. If still fail, re-burn CD-R/CD-RW.

NOTES ON SCHEMATIC DIAGRAM
•
Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

type.
•
Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic
capacitor, the expression “capacitance/withstand voltage”
is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
