Хорошее качество сканирования.
Мануал пришел часов эдак через 12. В целом доволен.
 ;
Fantastic quality and impressive delivery time. Based on this manual, I recommend this service without hesitation! Five Stars for certain.
;
Was happy to find the complete owners manual... It's all in there, just like the original...
;
Thanks for offering this item at such a good price. Proved handy in identifying the part I was looking for my set.

Thr Video Recorder i have is quiet Old and the Producer could Not help me. So i w as very glad to find an offer for the owners Manual for a very fair Price.a I obtained the original Manual very quick and I am happy to have it now.
FDL-252T SECTION 3 CIRCUIT ADJUSTMENTS
[SETUP](A BOARD )
1. Apply a DC voltage of 4.5V±0.1V to the J601 terminal (DC input jack) on the A board. 2. With S601 on the A board at UHF position, set the User Control RV550(VOL) and RV901(BRT) on the H board to their mechanical centers.
< A BOARD ALIGNMENT > 3-1.VIF.AFT ROUGH ALIGNMENT (T201, T202)
[SETUP] 1. Set S601 on the A board to VHF position. 2. Apply no signal to JL119 (RF). 3. Connect a 1 k� resistor between JL09 (+5.0V) and JL13 (RF AGC). 4. Apply a sweep signal across JL12 (IF) and JL14(IF GND). (Fig. 3-1) Note : Set the sweep signal for JL12 to -30±5dBm. Keep the distance to the ATT output JL12 as short as possible.
[+5.0V ALIGNMENT (RV600)](A BOARD )
Using a digital voltmeter measuring the voltage between JL09 (+5.0V) and JL87 (A.GND). Adjust RV600 to obtain the value shown below. Standard Value = 4.55V± 0.02VDC S601 position = UHF position
[+30.0V CHECK](A BOARD )
Check the voltage across JL07 (+30.0V) and JL87 (A.GND) . Standard Value = 32.5V±2.5VDC

[+7.5V CHECK](A BOARD )
Check the voltage across JL08 (+7.5V) and JL87 (A.GND) . Standard Value = 7.0V± 0.3VDC

[-10.0V CHECK](A BOARD )
Check the voltage across JL10 (-10.0V) and JL87 (A.GND) . Standard Value = -9.8V± 0.6VDC
1. Connect an oscilloscope between JL86 (VIDEO) and JL87 (A.GND) and apply an external voltage (MGC) to JL26 to obtain a waveform as shown in Fig. 3-2 (make sure not to clip the extremely short portion).Adjust T202 so that the position at 45.75 MHz is the lowest point. Note : Align JL26 (MGC) external voltage for approximately a 1.0 Vp-p. Make sure that the JL26 (MGC) external voltage does not exceed 4.3VDC. 2. Remove the external voltage (MGC) from JL26. 3. Connect an oscilloscope between JL02 (AFT) and JL01 (D.GND) and make a rough adjustment of T201 so that waveform is close to zero at the 45.75 MHz position. 4. Remove the 1 kilohm resistor connected between JL09 (+5.0V) and JL13 (RF AGC).
