13. Display of Reference Signals
Electrocardiographic (ECG) reference signals can be displayed during B-mode display,
B Dual mode display, M-mode display, and M+B mode display. This function is optional.
WARNING:
CAUTION:
1. To prevent electric shock, check the following items
before operation.
• There must be no abnormality of the ECG cable.
• The ECG cable must be connected correctly.
2. Connect the ECG cable to the system before attaching the
ECG electrodes to the patient. After the electrodes are
attached to the patient, be careful not to allow them to
come into contact with ground or other electrically live
parts. If the ECG cable connector or an electrode comes
into contact with ground or other electrically live parts,
the patient may receive an electric shock.
3. Do not place the ECG electrodes in direct contact with the
patient's heart. Cardiac arrest may occur.
* The ECG electrodes are of the BF type and are not
designed to be placed in direct contact with the heart.
4. To reduce the risk of electric shock or burns, use only the
cable and patient leads supplied with the reference signal
unit .
5. The ECG electrodes used should be commercially
available products provided by the customer.
6. Before using equipment such as an electric scalpel, high-
frequency therapy equipment, an electro simulator, or a
defibrillator, remove the ECG electrodes from the patient.
In addition, do not allow ultrasound transducers to come
into contact with the patient. The patient may be burned
or receive an electric shock.
The displayed reference signals should be used for reference
only. They should not be used for diagnosis or monitoring. In
patients with cardiac pacemakers, an implantable electro
stimulator, or arrhythmia, the heart rate or other parameters
may not be displayed correctly.
