CHAPTER 5. SCHEMATIC DIAGRAM AND WIRING SIDE OF P.W.BOARD

[1] NOTES ON SCHEMATIC DIAGRAM

• 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 without
such a symbol is microfarad. As to electrolytic capacitor, the expres-
sion "capacitance/withstand voltage" is used.
(CH), (RH), (UJ) : Temperature compensation
(ML) : Mylar type
(S) : Styrol type
(PP) : Polypropylene type

TM200 CIRCUIT DIAGRAM AND PWB LAYOUT
• The indicated voltage in each section is the one measured by Digital
Multimeter between such a section and the chassis with no signal
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.
