(A)	RX VCO	3ch Talk	-	∙ Confirm so that the reading of the Digital Voltmeter is 2.0V ± 1.0V.	IC1, L10,
	Confirmation				C26, R14
(B)	TX VCO	3ch Talk	T6	∙ Adjust T6 so that the reading of the Digital Voltmeter is 2.0V ± 0.3V.	IC1, DV1,
	Adjustment				T6
(C)	TX Frequency	3ch Talk	VC1	∙ Adjustment VC1 so that the reading of the frequency counter is	IC, X1, T6,
	Adjustment			30.1750MHz ± 100Hz.	DV1, C35,
					C40, VC1
(D)	TX Power	3ch Talk	T5	∙ Adjust T5 so that the reading of the RF VTVM is more than 9dBm.	IC1, Q3,
	Adjustment				Q4, Q5,
					T5, DPX1
(E)	RX Sensitivity	3ch Talk	T2	1. Apply 60dBuVemf output from S.S.G. (modulation frequency 1KHz, dev.	DPX1, T2,
	Confirmation			0KHz).	CF1, CF2
	(2nd IF output)			2. Confirm that the reading of RF VTVM is the maximum value (more than
				20mV)
(F)	Line Output Level	3ch Talk	-	1. Apply 60dBuVemf output from S.S.G. (modulation frequency 1KHz, dev.	IC1, Q11
	Confirmation			3KHz).
				2. Confirm that the reading of AF VTVM is more than 120mV (600Ω load).
(G)	Line Input	3ch Talk	-	1. Input via loop simulator 1.0KHz, -20dBm (measured at T-R) signal.	IC1, DV1
	Modulation			2. Apply 60dBuVemf output from S.S.G. (modulation frequency 1KHz, dev.
	Confirmation
				0KHz).
				3. Confirm so that the reading of FM Deviation Meter is 2.8KHz ± 0.3KHz.
(H)	Noise Squelch	3ch Talk	-	1. Measure the SSG output level when the noise squelch changes from Low	IC1, DPX1
	Confirmation			to High.
				2. Confirm that the SSG output level is -10 ~ +5dBuVemf.
