Display Overview
The device features a ¼ VGA 320 x 240 pixels LCD color display for valuable preview of ECG waveform, function
key labels, and other parameters as explained below. During ECG acquisition, notification messages will also
appear on the display. (See Section 3,
ECG Acquisition, Printing, Storage.)

Heart Rate (HR):
When a patient is connected to the electrocardiograph, his/her HR is displayed in real time. The HR is the average
ventricular rate measured over an average of the patient’s last five beats.
Speed:
Use F3 (Speed) to select display speed or rhythm printout speed: 5 mm/s, 10 mm/s, 25 mm/s, or 50mm/s.
Paper speed is printed at the bottom right corner of the ECG printout.
Gain:
Use F4 (Gain) to select waveform amplitude for display and printout: 5 mm/mV, 10 mm/mV, or 20 mm/mV.
Gain is printed at the bottom right corner of the ECG printout.
Filter:
Use F5 (Filt) to select the low-pass filter options: 40 Hz, 150 Hz, or 300 Hz for ECG printouts. Filter is printed at
the bottom right corner of the ECG printout.
WARNING: When the 40 Hz filter is used, the frequency response requirement for diagnostic ECG equipment
cannot be met. The 40 Hz filter significantly reduces high-frequency components of the ECG and pacemaker
spike amplitudes and is recommended only if high-frequency noise cannot be reduced by proper procedures.
