•
Resistor:
To differentiate the units of resistors, the symbols K and M are
used. The symbol K means 1000 ohm and the symbol M means
1000 kohm. The resistor without any symbol is an ohm resistor.
•
Capacitor:
To indicate the unit of capacitor, the symbol is used.
The symbol P means pico-farad and the unit of the capacitor with-
out such a symbol is microfarad. As to electrolytic
capacitor, the
expression “capacitance/withstand voltage” is used.
(CH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(S): Styrol type
(PP): Polypropylene type
•
The indicated voltage in each section is the one measured by Digi-
tal Multimeter between such a section and the chassis with no sig-
nal given.
•
Conditions: SIM card inserted, power on, in stand-by mode
(opened)
•
Schematic diagram and Wiring Side of P.W. Board for this model
are subject to change for improvement without prior notice.
•
Parts marked with “
” are important for maintaining the safety of
the set. Be sure to replace these parts with specified ones for main-
taining the safety and performance of the set.
