Good,readable manual. I found other manuals that were not readable when it came to part ID, but the one downloaded from owner-manual.com was better than expected. I will do buisness with owner-manual.com again.

Service Manual that I received was very helpful to me. Thank you.
;
The manual is well organized and is easy to read. The chapters are following normal way to proceed.

This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

Very useful service manual, was exactly what i needed.Good quality,reasonable price.Thank you.
Procedure n Perform the checking with the MIC input connector shortcircuited. (1) Set the spectrum analyzer as follow: CENTER FREQUENCY (fc): CE21 model; 470.125 MHz CE33 model; 566.125 MHz CE62 model; 798.125 MHz CE67 model; 838.125 MHz U14 model; 470.125 MHz U30 model; 566.125 MHz U62 model; 758.125 MHz U66 model; 782.125 MHz REFERENCE LEVEL: 20 dBm FREQUENCY SPAN: 200 kHz (20 kHz/DIV) RBW (resolution band width): 3 kHz VBW (video band width): 1 kHz ATT: 30 dB (2) Decrease gradually the DC output voltage of the DC regulated power supply and confirm that the battery alarm signal turns on at 2 ± 0.2 V. (3) Check that level difference between carrier frequency (center frequency level) on spectrum analyzer and tone signal is with in 29 ±2 dB.
20 dBm
2. Frequency check
Connections (For connecting the DC power supply, refer to the �Preparations� on page 3-2.)
MM-SMA (J)connector with SMA-BNC (J) connector Spectrum analyzer
CN301
Jumper wire TP200
MB-940 Board (A side)
TP501 (GND)
Connect a jumper wire between TP200 and TP501 (GND) by soldering. (TONE signal : OFF).
Procedure n Perform the checking with the Mic input connector (SMC94P) short-circuited. (1) Set the modulation analyzer as follows: MEASUREMENT: FM MEASUREMENT RANGE: ± 40 kHz HPF: 4 kHz LPF: >20 kHz DE EMPHASIS: OFF (2) Set the DC output voltage of DC power supply to 1 ± 0.1 V so that battery alarm signal goes on. (3) Check that frequency counter (resolution:0.1 Hz) reading is 32.782 kHz ±1 Hz. (4) After the checking, remove (unsolder) the jumper wire between TP200 and TP501 (GND) on the MB-940 board (A-side).
