TC-700P Service Manual

Circuit Description

1. Circuit Composition

The general circuit is composed of PLL-VCO, TX circuit, RX circuit, baseband processing circuit, power

supply circuit, MCU control circuit and etc.

2. Power Supply

TC-700P adopts the "soft power-down” feature. The battery supplies voltage B+ via the 3A fuse to

TC-700P radio. U601 supplies power to the motor via Q601; U602 supplies 5V (M5V) voltage to the

control circuit; U604 supplies 5V (C5V) voltage to the common circuit; U603 supplies T5V, R5V, 5CNS

voltage. During transmitting, T5C turns to high voltage, and Q607 is turned on to supply 5V (T5V)

voltage to the TX circuit. During receiving, R5C turns to high voltage, and Q606 is turned on to supply 5V

(R5V) voltage to the RX circuit.
