Circuit Description of the Onkyo TA-630DM
(1) Set the time of the timer unit plugged into the AC mains.
(2) Press the record key and/or the play key, and also the pause key. Then turn the power switch on.
(3) The power supply will thus come on at the preset time.
(4) C701 will consequently be changed up via R702, resulting in Q701 being turned ON some 4 seconds later.
(5) Q702 will therefore turn OFF.
(6) The signal will pass via S701 and C702, on to the gate of Q704.
(7) Q704 will thus be turned ON.
(8) The charge on C707 will then be discharged through solenoid and Q704, which is thereby activated.
(9) The pause key is released by this solenoid action, resulting in the start of the recording, or playback, mode.
