Doubted for buy this manual as it is my first order here and at not have cover image, I assumed would haven't. However, within 24 hs, already possessed the link to download it. The manual are scanned correctly and have all what is needed. Includes adjustments and diagrams of all circuits. Very satisfied.
the manual is in quite good quality and it's in pdf. manual was send in less then 6h.

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.
