There was no problem at all.After paying i had to wait only a few hours,than i could
download the manual in best pdf-quality.
Thank You !
 ;
I found this service manual to be complete in every detail except for troubleshooting charts. It would be helpful if it had a set of troubleshooting charts; however it is a very good manual otherwise and for the price it is very well worth it.
;
Complete manual included schematics layouts and alignment procedure, clear to read and magnify, extremely pleased with manual and owner manual . com's service
;
perfect, i am very satisfait for the réception of the sansui r-5l service manual, thank you very much
;
Thank you, this is a rare document. Few others have it, but they charge way more for a download.
Great deal (even if you have to wait a few hours to get it).

Automatic Power Control (APC) Purpose of the Automatic Power Control (APC) is to generate an envelope signal to control the power ramping up, ramping down and power level of the radio burst. The APC structure is intended to support single slot and multi-slots transmission with smooth power transition when consecutive bursts are transmitted at different power level. It includes a DAC and a RAM in which the shape of the edges (ramp-up and ramp-down) of the envelope signals are stored digitally. This envelope signal is converted to analog by a 10 bits digital to analog converter. Timing of the APC is generated internally and depends of the real time signals coming from the TSP and the content of two registers which control the relative position of the envelope signal versus the modulated I & Q.
Time serial port (TSP) Purpose of the time serial port is to control in real time the radio activation windows of IOTA which are BUL power-on, BUL calibration, BUL transmit, BDL power-on, BDL calibration and BDL receive and the ADC conversion start. These real time control signals are processed by the TPU of DBB and transmitted serially to ABB via the TSP, which consists in a very simple two pins serial port. One pin is an enable (TEN) the other one the data receive (TDR). The master clock CK13M divided by 2 (6.5MHz) is used as clock for this serial port. Voice band Codec (VBC) The VBC processes analog audio components in the uplink path and transmits this signal to DSP speech coder through the voice serial port (VSP). In the downlink path the VBC converts the digital samples of speech data received from the DSP via the voice serial port into analog audio signal. Additional functions such as programmable gain, volume control and side-tone are performed into the voice band codec.
Micro-controller serial port (USP) The micro-controller serial port is a standard synchronous serial port. It consists in three terminals, data transmit (UDX), data receive (UDR) and port enable (UEN). The clock signal is 13MHz clock. The USP receives and sends data in serial mode from and to the external microcontroller and in parallel mode from and to the internal GSM Baseband a Voice A/D D/A modules. The micro-controller serial port allow read and write access of all internal registers under the arbitration of the internal bus controller.
