It also functions as a dial, which changes a value by turning to the left or right, and as a button, which operates by pressing. The [Menu] dial-button is an example. This dial-button is to execute the currently selected menu item. Turning the dial-button to the right, you can select the upper menu items of the current menu. Turning to the left, you can select the lower menu items.

Dial The dial is the control that increases or decreases the value upon turning to the right or left, respectively. The [Gain] dial is an example.

Up-Down Switch The up-down switch is a control that increases a value while it is up and decreases a value while it is down. The [Scale] switch is an example. When you switch it up or down, the focusing point ascends or descends, respectively.

Image Mode & Gain Control

2D In 2D mode, it is possible to examine organs in direction of the depth of scanning in real time. Because this system includes 2D image basically, except for some special cases, you cannot turn the 2D off when desired. Therefore, the [2D] button does not work as a toggle although it gives LED feedback. Instead, it is used as a button to return to the basic 2D mode even from any other image modes.a

M This button is to turn the M Mode on. It is possible to observe one desired line of 2D images as time goes by. While the M Mode is on, one more press of this button turns it off.

C This button is to turn the Color Mode on. Patterns of bloodstream are shown in 2D screen in real time. While the color mode is on, one more press of this button turns it off.

D This button is to turn the PW Spectral Doppler Mode on. It is possible to observe blood vessel or bloodstream of heart. Spectral Doppler also can be used with 2D mode at the same time. While the PW Spectral Doppler Mode is on, one more press of this button turns it off.

PD This button is to turn the Power Doppler Mode on. While the Power Doppler Mode is on, one more press of this button turns it off.

Dual This button turns the Dual Mode on. You can compare two 2D images in Dual mode. While the dual mode is on, one more press of this button turns it off. You can use the [Set] button or [Dual] button to change the left/right view direction of the activated image in Dual Mode.

Electrical Safety This equipment has been verified as a Class I device with Type BF applied part. For maximum safety observe these warnings:

Warning

Shock hazards may exist if this system, including all externally mounted recording and monitoring devices, is not properly grounded.

In a hospital, doctors and patients are subjected to dangerous, uncontrollable compensating currents. These currents are due to the potential differences between connected equipment and touchable conducting parts as found in medical rooms. The safe solution to the problem is accomplished with consistent equipotential bonding. Medical equipment is connected with connecting leads made up with angled sockets to the equipotential bonding network in medical rooms.

Warning

Do not remove the protective covers on the system; hazardous voltages are present inside. Cabinet panels must be in place while the system is in use. All internal adjustments and replacements must be made by a qualified Medison Customer Service Department. Do not operate this system in the presence of flammable gases or anesthetics. Explosion can result.

To avoid risk of electrical shock hazards, always inspect all the probes before use; check the face, housing, and cable before use. Do not use, if the face is cracked, chipped, or torn, the housing is damaged, or the cable is abraded. To avoid risk of electrical shock hazards, always disconnect the system from the wall outlet prior to cleaning the system. All patient contact devices, such as probes, ECG leads must be removed from patient contact prior to application of a high voltage defibrillation pulse. To avoid risk of electrical shock, do not use any probe that has been immersed beyond the specified cleaning or disinfection level. See ‘Chapter 11. Maintenance’ in this manual. Conductive parts of electrodes shall not contact other conductive parts including earth. To avoid risks of electrical shock and fire hazards, inspect the system power cord and plug on a regular basis. Ensure that they are not damaged in any way. To avoid risk of electrical shock hazards, accessory equipment connected to the along the digital interfaces must be certified according to the representative IEC standards (I.e. IEC60950/EN60950 for data processing equipment and IEC60601-1/EN60601-1 for medical equipment). Furthermore all configurations shall comply with the system standard IEC60601-1-1/EN60601-1-1. Everybody who connects additional equipment to the signal input part or signal output part configurations a medical system, and is therefore responsible that the system complies with the requirement of IEC60601-1-1/EN60601-1-1. If in doubt, consult the Medison Customer Service Department. Do not touch the SIP/SOP and patient simultaneously. It may cause a leakage current exceeding the maximum allowable values. Do not perform any changes or repairs on the ECG-amplifier, the connecting cables or the patient cable. A defective patient cable must be exchanged. Only authorized service personnel must perform necessary repairs.

This device is not intended to provide a primary ECG monitoring function, therefore, does not have means of indicating an inoperative electrocardiograph. Do not use ECG electrodes for HF surgical equipment. It can cause the hazard of burns in the event of defect in HF surgical equipment. Do not use ECG electrodes during the operation of a cardiac pacemaker or other electrical stimulators. It can cause any safety hazard to a patient. Do not use ECG leads and electrodes in an operating room.

■ Although your system has been manufactured in compliance with existing EMI/EMC requirements, use of this system in the presence of an electromagnetic field can cause momentary degradation of the ultrasound image. If this occurs often, MEDISON suggests a review of the environment in which the system is being used, to identify possible sources of radiated emissions. These emissions could be from other electrical devices used within the same room or an adjacent room. Communication devices such as cellular phones and pagers can cause these emissions. The existence of radio, TV, or microwave transmission equipment located nearby can cause emissions. In cases where EMI is causing disturbances, it may be necessary to relocate your system. ■ E lectrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by heating or air conditioning. During low humidity conditions, electrical charges naturally build up on individuals and can create static shocks. An ESD condition occurs when an individual with an electrical energy build-up comes in contact with objects such as metal doorknobs, file cabinets, computer equipment, and even other individuals. The static shock or ESD is a discharge of the electrical energy build-up from a charged individual to a lesser or non-charged individual or object. The level of electrical energy discharged from a system user or patient to the ultrasound system can be significant enough to cause damage to the system or probes. The following precautions can help to reduce ESD: anti-static spray on carpets; anti-static spray on linoleum; anti-static mats; or a ground wire connection between the system and the patient table or bed.
