The FCP-7101/FX-7102 is equipped with the following four boards.
1.MAIN BOARD (PCB-6950)
2.KEY BOARD (PCB-6949)
3.SENSOR BOARD (PCB-6948)
4.MAG UP BOARD (PCB-6951)
The MAIN BOARD (PCB-6950) amplifies the ECG signals input from patient connectors
at the ECG AMP block, and after AD conversion, performs various processing,
measurements and analyses such as ECG display, recording, checking for arrhythmia and
R-R intervals.
The KEY BOARD (PCB-6949) is equipped with keys (switches) for operating this
instrument. Various operations can be carried out from the key board. It is also equipped
with the LED that indicates the operation status of the power supply (AC or DC) and the
charging status of the battery.
The SENSOR BOARD (PCB-6948) is equipped with a sensor for detecting the mark
position of Z-fold recording paper (OP-122TE, OP-123TE) and a sensor for judging the
presence of recording paper.
The MAG UP SENSOR (PCB-6951) is equipped with a switch for detecting the
open/close status of the magazine.
