This manual is for the usa model only. But it is clear
, accurate and comprehensive, including board layouts and schematics.
I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955

For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers).
Yes, there are free manual sites out there, but if they don't have what you want, you have to pay.
And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures.
My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse.
Schematics and text are clear.
I'll be happy to purchase from here again.

Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe

I was skeptical at first but later found the manual to be good quality for the price. It took a couple hours to receive the email with the download link, well worth the wait. Thanks.
SECTION 5 ELECTRICAL ADJUSTMENTS
5-1. BASE UNIT SECTION
3. Checking TX Output Setting:
peak power meter
� Make the set in Test mode (see page 10) 1. Checking RX I&Q Output Level Setting:
oscilloscope + � level meter + � TP558: RXIP TP557: RXIN TP556: RXQP TP555: RXQN TP567: GND
SSG
+ �
ANTENNA TERMINAL
ANTENNA TERMINAL
Procedure: 1. Place the base unit in the Continuous Transmit more (CH1, High power). 2. Measure the ANT OUT output of the RF module in the base unit using a peak power meter. 3. Confirm that the measured output is 85 mW (MIN 30 mW). 4 .Also, execute steps 1 through 3 for the channels 10 and 20. CH10: 80 mW (MIN 25 mW) CH20: 80 mW (MIN 25 mW)
Procedure: 1. Place the base unit in the Continuous Receive mode (CHI, LNA ON, AGC ON). 2. Set the SSG frequency to the frequency on CHI + 300 kHz, and the RF output level to - 95 dBm. 3. Measure the output level 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 -25.0 to -19.0 dB V. IF IC501 was replaced (there is no ID data), the output level is 30.0 to -24.0 dB V. 5. Also, execute steps 1 through 4 for the channels 10 and 20. * For the frequency on each channel, see page 7. 2. Checking TX Center Frequency Setting: � short: TP515� TP567 (GND)
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Short TP515 (GND) and TP567 (GND) on the BASE MAIN board in the base unit. 2. Place the base unit in the Continuous Transmit more (CH1, High power). 3. Measure the ANT OUT frequency of the RF module in the base unit using a frequency counter. 4. Coufirm that the measured frequency is 904.200 MHz ± 27kHz. 5. Also, execute steps 1 through 4 for the channels 10 and 20.
