FM TUNER LEVEL CHECK

signal generator

set

Procedure:

1.Turn on the set.

2.Input the following signal from Signal Generator to FM antenna input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz

Deviation	: 75 kHz
Modulation	: 1 kHz
ANT input	: 35 dBu (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and the set.

You cannot use video cable for checking.

Use signal generator whose output impedance is 75 ohm.

3.Set to FM tuner function and tune A, B and C signals.

4.Conﬁrm “TUNED” is lit on the display for A, B and C signals.

When the selected station signal is received in good condition, “TUNED” is displayed.
