Turn AM Signal Generator Modulation ON2. Adjust RSX-1055 AM Freq. to 603KHz (or 600KHz) and measure output level with Audio Signal analyzer.3. If it is lower than 200mV , Adjust output level to maximum point with RF BLOCK BLACK COIL ( AM-ANT ). ( recommand higher than 250mV )4. Set Generator RF & RSX1055s RF to 999kHz(or 1000kHz) and measure output level with Audio Signal analyzer.

Turn AM Signal Generator Modulation ON ( Make sure if Output level is 84dB )2. If TUNED indicator does not turn on at higher than 8086dB(Generator output), Adjust SVR01 ( AM-ADJ ) up to the moment where TUNED indicator tunrs OFF & ON again3. Confirm if TUNED turns OFF when decreasing the output level of AM Signal Generator slowly from 84dB to 80dB.4. Push RSX-1055 TUNE UP or DOWN button long at AM Signal Generator Output Level 84dB and start AUTO search.

So some of menu or option name may not be matched with some versions of Windows 98. First of all, User should have the new software file (ROTEL supply) before proceeding the software up-grade process. 1. Power RSX-1055 off. 2. Remove all of connections between RSX-1055 and other equipments. 3. Connect RSX-1055 and PC with RJ45/DB9 cable. RJ45 jack should be connected to COMOUTER I/O port in RSX-1055 rear panel. DB9 jack will be connected to PC serial port (ex. COM1 or COM2,). 4. Switch down the SOFTWARE UPGRADABLE key to ON in RSX-1055 rear panel. 5. Open HyperTerminal program in Windows 98 (Program / Supplement Program / Communication / HyperTerminal) 6. Input name and select icon to use for connection in connection explanation dialogue box and click O.K. 7. Connection object dialogue box appears. Select modem(N) to use for connection. For example, if DB9 cable is connected to COM1 serial port of PC, select COM1. 8. Selected serial port registration dialogue box appears. Select value or option per item as follows. *Bit per second (B) : 19200 *Data Bit (D) : 8 *Parity (P) : None *Stop Bit (S) : 1 *Flow Control (F) : None *And click O.K. 9. Click File (F) and click Property (R) in file menu of HyperTerminal. 10. Select setup. 11. In set up dialogue box, select options per item as follows. *Function Key : Terminal Key(T) *Backspace function: Ctr+H(C) *Emulation: VT100 *Telnet Terminal: VT100 *Back scroll buffer line : 500 *And click ASCII Setup (A) *Select (A) & (W) at ASCII receiving section, Click O.K *Click O.K 12. Power RSX-1055 on and then options message appears in HyperTerminal screen. In the message, select number 1. Erase of current software begins. 13. When erasing finishes, download file message appears. Select Text file sending (T) in Transmission menu (T)of HyperTerminal and text file sending dialogue box appears. 14. Change the finding file format from (*.TXT) to (*.*) format, and find the new software which is for up-date.( *. Bin) format. 15. Double-click new software file. The extension of software file name is bin (ex. xxx.bin). Then software upgrade begins. 16. When the upgrade finishes, check message appears. In the message, compare received data checksum with rom checksum. If they are same, the upgrade is done correctly. 17. Power RSX-1055 off and switch up the SOFTWARE UPGRADABLE key to Off in the rear panel. 18. Disconnect the cable between PC and the RSX-1055 19. Power RSX-1055 on and set the default setting on the OSD screen menu with connecting a TV monitor. And confirm if the software version is upgraded. 1612V-TRIG BDX-1339-04CAPACITOR BDX4002002710X-4002002700POWERTRANSSPKR BDAMP BDE-4002000200TERMINAL B DX-1339-02FRONT BDX1338-02X-1338-01X-1338-03MAINVOLUME BDTUNER BDMAIN BD016E-1337016X-1338-04016X-1331STAND-BY BDCENT-SPKR BDS-VIDEO BDDIGITAL I BDDIGITAL II BD016E-1332016E-1325016X-1333016X-1339-02016X-1339-03POWER-SWBDRMC SENSORBDWiring DiagramRSX-1055CP101(9P)CN407(14P)CP100(5P)CN100(5P)CN505(14P)CP505(14P)CN109(2P)CN204(2P)CN202(2P)GP802CN203(3P)CN954(3P)CT911(3P)CT910(2P)CP903(3P)CP904(7P)CP905(4P)CP106(7P)CN107(5P)CN402(12P)CN405(4P)CN401(15P)CN601(10P)G802GP803CP906(2P)CP908(3P)CN108(3P)CN602(8P)CP900CN901(2P)G803CP951(3P)ACDC-OUTANALOG SignalGNDGNDCP952(2P)CN953(3P)CT202(2P)CT203(2P)CNT951(2P)CT951(2P)CN205(3P)CP201(10P)AC INLETCP906(2p)CP905(2P)CP901(9P (5P)CN907(4P)CP107(4P)CP103(3P)CP109(2P)CP108(3P)CP407(14P)CP602(8P)CP601(10P)CN404(12P)CP402(12P)CP404(12P)CP401(15P)CP405(4P)CP501(6P)CN101(9P)CP503(7P)CP502(15P)CN201(10P)CN502(15P)CP504(15P)CN504(15P)CN503(7P)CP901(2P)CN103(3P)CNT105(2P)CP110(3P)CN106(7P)CN501(5P)CP1050(2P)CP102(4P)CN110(3P)CN102(4P)POSISTORLEDPOWER TRANS17PCB Assembly -1Front PCB 016 X-1338A01 - 0618RSX-1055PCB Assembly -2RSX-1055Main PCB 016 E-1337A0019PCB Assembly - 4Top Side ViewBottom Side ViewDIGITAL1 PCB 016E-1332C00RSX-105520PCB Assembly -5Top Side ViewBottom Side ViewDIGITAL 2 PCB 016E-1333C00S-Video PCB 016 X-1331B00Top Side ViewBottom Side ViewRSX-105521PCB Assembly -6 Terminal PCB 016 X-1339A01 - 04RSX-105522PCB Assembly -7POWER AMP PCB 4002000200ACAPACITOR PCB 4002002710-BTOP VIEWBOTTOM VIEWSTANDBY PCB 4002002700-BRSX-105523PCB Assembly -8Tuner PCB 016 E-1325 Top Side View Tuner PCB Bottom ViewRSX-105524Block Diagram RSX-105525CXP82832_338QSchematic Diagram - 1/13 Front Board X-133826RSX-1055Schematic Diagram -2/13 Digital 1 Board (1/3) E-133227Schematic Diagram -3/13 Digital 1 Board (2/3) E-133228Schematic Diagram -4/13 Digital 1 Board (3/3)E-133229Schematic Diagram -5/13 Digital 2 Board (1/2) X-133330Schematic Diagram -6/13 Digital 2 Board (2/2) X-1333314002000200APower Amplifier PCB220220220220220Schematic Diagram - 7/1332Schematic Diagram -8/13 Main Board (1/3) - Input Selector E-133733Schematic Diagram -9/13 Main Board (2/3) - Regulator, OSDE-133734Schematic Diagram -10/13 Main Board (3/3) - ZoneSchematic DiagramListening, Zone Select BoardE-1337351K5Schematic Diagram -11/13 Terminal Board X-133936BSchematic Diagram -12/13 S-Video BoardX-133137Schematic Diagram - 13/13Standby Board40020027004002002710Capacitor BoardTuner BoardE-1325B38
