18. Drive
This menu is used to operate the drive using drive-related diagnos-
tic and tools.

Note: Not used for the servicing.

:

Procedure:
1.  Turn the power on.
2.  Input the following signal from Signal Generator to FM an-

tenna 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: Please use 75 ohm “coaxial cable” to connect SG and the set. You 

cannot use video cable for checking.

 

  Please use SG whose output impedance is 75 ohm. 

 
3.  Set to FM tuner function and scan the input FM signal with 

automatic scanning.

4. Confi rm that input Frequency of A, B and C detected and auto-

matic scanning stops.

 
The stop of automatic scanning means “The station signal is re-
ceived in good condition”.

Check that the output voltages of the switching regulator

(SWR1) are the following value.

CN301 pin 5: 12 V (ICUNSW12V)

CN301 pin 6: 12 V (UNSW12V)

CN301 pin 7: 12 V (FL12V)
