If the fluctuating range of the ECG signal is great, it’s better to choose AGC because the
sensitivity can be adjusted automatically in this mode.
Note: This key is ineffective during the printing course in the auto mode.
3) RESET (Lead Locking Key)
In the manual mode, during the printing course, pressing this key can lock the lead, and
then the corresponding ECG wave shows a straight line. The lead will be unlocked
automatically after 1 second. So in the case of baseline drift, press this key to draw the
baseline to zero quickly, and the ECG wave resumes after 1 second.
4) 1mV Calibration Key
In the manual mode, press this key to print a 1mV calibration mark during the printing
course.
5) MODE (Mode Switch Key)
Press this key to select a working mode among four auto modes and a manual mode. The
switch order of leads in each mode is listed in Table 2-1.
