A good service manual with lots of info and a very fair price
;
Great value, good scan, just as expected, everything that you need.
;
Good scan, great price, but almost the same with the SV260 service manual.
;
This PDF is very comprehensive. It includes drawings, parts lists, schematics, pictures, PCB drawings, mechanical layouts, etc. for all three stackable equipment. The scans are good too. Easy to read and no smudges or black lines. I have no complaints. I will make this site my first stop for finding my service manuals.

This service manual includes drawings, schematics, exploded views, parts list, operating details, and more. Very good scans, very readable. The only thing that made it a 4 star rating was on approximately 4 scans only half of the page was scanned then the other half. I would have preferred the pages to be whole scans.

3-2-12. Battery Alarm Signal Check
Equipment and Tools DC power supply DC output Voltage: +3.0 ± 0.1 V dc DC ammeter Frequency counter Spectrum analyzer Modulation analyzer MM-SMA (J) connector (Part No. J-6402-480-A) SMA-BNC (J) connector (Part No. J-6402-490-A) Switch and Control Setting The following setting is to be perform with the channel select switches (S504 and S505). Transmitting Channel setting: U64 model: 65-01 channel (776.125 MHz) U66 model: 67-01 channel (788.125 MHz) U68 model: 69-01 channel (800.125 MHz) RF power output switch (S401): 50 mW Input LEVEL control (RV101): �_60� (0 dB attenuation) Turn the RV101 clockwise fully.
Procedure n Perform the checking with the MIC input connector (CN101) short-circuited. (1) Set the spectrum analyzer as follow: CENTER FREQUENCY (fc): U64 model: 776.125 MHz U66 model: 788.125 MHz U68 model: 800.125 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: 20 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 ± 0.1 V. (3) While the TP201 is short-circuited to the frame (GND) with a tweezers etc (TONE signal ; OFF), check that level difference between carrier frequency (center frequency level) on spectrum analyzer and tone signal is with in 29 ± 1 dB.
