The service manual is really great - thanks to it I was able to install the laser unit and thus "save" my CD-player, which seemed to be impossible before I had the manual.

Downloaded the Service manual OK of the Technics Piano and have now repaired it and its going fine. Excellant; thank you for the fine servce. A.M

This site is working fine! Did buy a manual for SX-EX25L and after a while I could download it and fix the problem. Nice and easy!
;
Complete manual as pdf-file in very good quality. Very helpful and fast availability.
;
Complete service manual in very good scanning quality with all schematic and PWB graphics as well as assembly & maintenance instructions. A slight drawback is that the rastering of the PWB graphics sometimes makes it a bit difficult to follow fine traces, but no showstopper.

HANDSET 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 + � TP804: RXIP TP803: RXIN TP802: RXQP TP801: RXQN TP814: GND
SSG

ANTENNA TERMINAL (TP812)
ANTENNA TERMINAL
Procedure: 1. Place the handset in the Continuous Transmit more (CH1, 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 62 mW (MIN 25 mW). 4. Also, execute steps 1 through 3 for the channels 10 and 20. CH10: 64 mW (MIN 25 mW) CH20: 64 mW (MIN 25 mW)
Procedure: 1. Place the bandset in the Continuous Receive mode (CHI, LNA 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 IC401 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: TP820 �TP814 (GND)
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Short TP555 (GND) and TP814 (GND) on the HAND MAIN board in the handset. 2. Place the handset in the Continuous Transmit more (CH1, High power). 3. Measure the ANT OUT frequency of the RF module in the hand set 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.
