4. If the PLAY and RECORD buttons are simultaneously depressed without either of the REC TRACK buttons or CUE REC TRACK button being depressed the RECORD LED at left of the RECORD button will light in green to indicate the record ready state Under this condition if the REC TRACK button is depressed the LED above the RECORD TRACK button which correspond to the depressed channel will light and the RECORD LED change color from green to red If both L and R REC TRACK buttons or CUE REC TRACK button is released cancelled in the next step the RECORD LED will change color to green thus changing from record mode to the record ready mode With both L and channels and CUE channel in record mode and then record mode of L channel only is cancelled the RECORD LED will remain in steady lighting but the LED above the L channel RECORD TRACK button will be extinguished 17 Monitor selector INPUT SYNC REPRO If the INPUT button is depressed input signals of channels L R and CUE will go to the rear panel OUTPUT jacks and also be monitored by the meter If the SYNC button is depressed depending on whether the recorder is in the record mode or not either the input signal or sync output is obtained at the OUTPUT jack and monitored by the meter the REPRO button is depressed playback output of the reproduce head goes to the OUTPUT jack and the meter 18 RESET 0 BUTTON The counter display is returned to zero by depressing this button
