[1] Notes on schematic diagram

• Resistor:
Letters K and M are prefixed to ohm (unit of resistance).
K means 1000 ohms and M means 1000 kohms.
• Capacitor:
P is an abbreviation for "pico" and a farad (unit of capacitance)
without P means "microfarad". Expressions "capacitance/withstand
voltage" are used for electrolytic capacitors.
(CH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(S): Styrol type
(PP): Polypropylene type

• The voltage of each section is obtained by measuring between the
section and chassis using a digital multimeter [handset (phone) out
of range].
• Conditions: SIM card inserted, power on, in stand-by mode
(opened)
