Bardzo dobra jakość skanu, przystępna cena. Instrukcja serwisowa okazała się przydatna przy "reanimowaniu" dwudziestoparoletniego decka, który teraz pięknie gra :)

Charge detect: 0 = charging, 1 = not charging. Clock of EEPROM DTMF data pin 4 (Most Significant Bit) DTMF data pin 3-1 DTMF data pin 0 (Least Significant Bit) Country option select 2. Control the shunt resistor: 1 = shunt a resistor (For U, K ONLY) Country option select 1 PAGE key: 1 = PAGE ON, 0 = STANDBY Ground Combo chip strobe signal (TB31224F) Combo chip data signal (TB31224F). In-use LED: 1 = ON, 0 = OFF. Combo chip clk signal (TB31224F). Data Input/Output of EEPROM. Line seize: 1 = line seize, 0 = off-hook Telephone Line Mute Control: 1 = MUTE. Make/Break Ratio Select 1 = 33.3%, 0 = 40% Hook detect input (for Corded Phone). 1 = ON HOOK, 0 = OFF HOOK
