 ;
A good and useful manual. With these, We was abled to isolate and pin point the component that was causing the problem. The total time spent in troubleshooting is very much reduced.
 ;
The quality of the manual is top. The transfer worked perfect and fast.
No problems at all. Recommendable
;
Very good service for get any documentation. Fast and perfect quality.
;
Excellent service manual with all the necessary info. :)
;
The product dowload was delivered efficiently with emails to support its download availabilty. The contets of the manual was very eligible and of good quality. Will purchase from this site again!
VCC3, VCC5 voltage check PCB-LA � Voltage supply CP151 = 5.0 ± 0.05 V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 ± 0.05 V to CP150. (2) Make sure VCC3 (CP160) is 3.3 ± 0.1 V and VCC5 (CP152) is 5.0 ± 0.15 V.
VCC2 adjustment and VCC7, VCC8, VEE2 voltage check � Voltage supply VCL0(CP101)=5.0±0.05V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 V ± 0.05 V to VCL0 and adjust VR100 so that VCC2 will be 5.0 ± 0.02 V. Notes: � VCC7 = 7.3 ~ 8.3 [V], VCC8 = 12.0 ~ 14.0 [V] � VEE2 = �12.3 ~ �16.7 [V] In addition, disconnect the power and make sure all output voltages are 0 V.
VCO free run frequency adjustment � Voltage supply VCC2=5 V ± 0.05 (V) (CP181). VCC8 = 13.5 ± 0.05 (V) (CP180). VEE2 = �15.0 ± 0.05 (V) (CP182). Connect CP705 (CSY) and CP700 (GNP). (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Monitoring CP710 (HDB) with a frequency counter, adjust VR720 so that the frequency will be 15.734 ± 0.1 [KHz]. Notes: � Disconnect CP705 and CP700, then connect PCB-LA and make sure CP705 (CSY) and CP710 (HDB) are synchronized. � Keep room temperature at 20 ± 10°C. QV-770
