 ;
got exactly what i ordered in a very timely manner. will use again for other manuals
 ;
I'm happy. Good quality. Very helped me with my work..............................
;
This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

I do not have very much to say.
The price is quite covenient, delivery was better as promised (about 12 ours, against the specified 24 hours if I remember well), and the quality of the PDF is more than acceptable.
The Service Manual of Sansui R30 itself is also satisfactory: good graphic for schematics and layouts, simple and well structured.

HANDSET SECTION
3. Checking TX output Setting:
peak power meter + � ANTENNA TERMINAL
� Make the set in Test mode (see page 11) 1. Checking RX I&Q Output Level Setting:
oscilloscope + � level meter + � TP520: RXIP TP521: RXIN TP522: RXQP TP523: RXQP TP553: GND
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Place the handset in the Continuous Transmit mode (1CH, High power). 2. Measure the ANT OUT output of the RF module in the handset using a peak power meter. 3. Confirm that the measured output is 29 mW (MIN 17.4 mW). 4. Also, execute steps 1 through 4 for the channels 2 � 20.
Procedure: 1. Place the handset in the Continuous Receive mode (1CH, LNA, AGC ON). 2. Set the SSG frequency to the frequency on 1CH + 300 kHz, and the RF output level to �95 dBm. 3. Measure the output lvel of RXIN, RXIP, RXQN, and RXQP with a level meter. At this time, confirm with an oscilloscope that a sine wave of 300 kHz is output. 4. confirm that the measured output level is �23.3 to �20.9 dBV. If IC502 was replaced (there is no ID data), the output level is �28.3 to �25.9 dBV. 5. Also, execute steps 1 through 4 for the channels 2 � 20. * for the frequency on each channel, see page 7.
2. Checking TX Center Frequency Setting: � short: TP555 � TP553
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Short TP555 and TP553 (GND) on the MAIN board in the base unit. 2. Place the handset in the Continuous Transmit mode (1CH, High power). 3. Measure the ANT OUT frequency of the RF module in the handset using a frequency counter. 4. Confirm that the measured freuquency is 903.600 MHz ± 27 kHz. 5. Also, execute steps 1 through 4 for the channels 2 � 20.
