Operation Preparations
3.2 Preparing the Patient
3.2.1 Instructing the Patient
Before attaching the electrodes, greet the patient and explain the procedure. Explaining the
procedure decreases the patient’s anxiety. Reassure the patient that the procedure is painless.
Privacy is important for relaxation. When possible, prepare the patient in a quiet room or area
where others can’t see the patient. Make sure that the patient is comfortable. The more relaxed
the patient is, the less the ECG will be affected by noise.
3.2.2 Cleaning the Skin
Thorough skin preparation is very important. The skin is a poor conductor of electricity and
frequently creates artifact that distorts the ECG signal. By performing methodical skin
preparation, you can greatly reduce the possibility of the noise caused by muscle tremor and
baseline drift, ensuring high-quality ECG waves. There is natural resistance on the skin surface
due to dry, dead epidermal cells, oils and dirt.
To clean the skin
1. Shave hair from electrode sites, if necessary. Excessive hair prevents a good connection.
2. Wash the area thoroughly with soap and water.
3. Dry the skin with a gauze pad to increase capillary blood flow to the tissues and to remove the
dead, dry skin cells and oils.
3.3 Connecting the Patient Cable to the
Electrocardiograph and Electrodes
WARNING
The performance and electric shock protection can be guaranteed only if original patient
cable and electrodes of the manufacturer are used.

Disposable Electrode connection
1) Align all lead wires of the patient cable to avoid twisting, and connect the alligator clips to
the lead wires.
2) Clean the electrode areas on the body surface with 75% alcohol.
3) Attach the disposable electrodes to the electrode positions on body surface.
4) Clip the disposable electrodes with the alligator clips.
The quality of ECG waveform will be affected by the contacting resistance between the patient
and the electrode. In order to get a high-quality ECG, the skin-electrode resistance must be
minimized when you attach electrodes to patients.
CAUTION
The disposable electrodes can only be used for one time.

Troubleshooting
Chapter 8 Troubleshooting
1) Operating Problems
Q1: I want to save the ECG data without any printing, could it be possible?
A1: Yes, in the Record Info setup, set Print Out to Off. In the same way, if the
transmission settings have been configured, the ECG data could be transmitted to the
PC without printing.
2) Printing Problems
Q1: There was double impression in printing when I printed ECG reports by using an
ink-jet printer. What’s wrong with it?
A1: It may be the result of the coexisting black and color ink cartridges. Taking out the
color ink cartridge may solve the problem.
Q2: I was encountered with paper-jam, what was I supposed to do?
A2: If it happened for the first time, it might be the result of an inappropriate placement of
the paper. In this case, please open the paper casing, pull the paper out of the paper
tray, tear the pages with rumples, and then put the paper in the paper tray again, adjust
the position of the paper carefully and close the casing.
Q3: The hint PaperErr is displayed on the screen, what should I do?
A3: Check if the paper maker setting is right or might be the result of unsuccessful
detection of the black markers, first open the paper casing so as to clear the error
information, and then check whether the black marker is on the top of the paper.

The electrocardiograph is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the electrocardiograph can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the electrocardiograph as
recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
