It is important to clean and maintain the ultrasound system and peripherals. Thorough cleaning is particularly important for pieces of peripheral equipment because they contain electromechanical devices. If exposed to constant and excessive environmental dust and humidity, these devices will suffer in both performance and reliability.
This section includes the following information for cleaning and maintaining the system.
Cleaning the System and ECG Equipment
Use this method to clean the system and the ECG equipment. The system and ECG cables, leads, and electrodes can be cleaned using a mild soap solution. If the equipment has come in contact with blood or infectious material, clean the equipment with an 70% solution of isopropyl alcohol. For instructions on disinfecting system surfaces, see Disinfecting System Surfaces.
WARNING: Always use protective eyewear and gloves when cleaning and disinfecting any equipment.
Cautions:
- Attempting to disinfect a cable or connector by using a method other than the one included here can damage the device and voids the warranty.
- Orient the parts that must remain dry higher than the wet parts until all parts are dry.
To clean the display; the system control panel; all the external surfaces of the system and the cart; the ECG trunk cables, leads, and electrodes
1. Before cleaning, turn off the system and unplug the power cord from the power source.
2. Wipe with a soft cloth moistened with soap and water.
Caution: Do not spill or spray liquid on the controls, into the system cabinet, or into the transducer connection receptacle.
3. Remove any solid matter around the keys or the controls with a cotton swab or toothpick to ensure that solids 4. are not pushed into the cabinet.
If blood or other infectious material comes in contact with the system or any cable other than a transducer cable, wipe with a 70% solution of isopropyl alcohol.
Caution: If blood or other infectious material comes in contact with a transducer or transducer cable, do not wipe with isopropyl alcohol until you have read Cleaning, Disinfecting, and Sterilizing Transducers for specific cleaning guidelines. Isopropyl alcohol should not be used on some parts of the transducer and should never be used on any parts of the transducer cable. Additional cleaning agents are also available for transducers.
5. Remove any residue with a cloth moistened with sterile water.
6. Be sure to dry the equipment to prevent potential corrosion.

Disinfecting System Surfaces
T he exterior surfaces of the system can be disinfected using a recommended disinfectant with a wipe method. The following products are approved for use on the system:
- Mild soap solution
- 70% Isopropyl alcohol (IPA)
- Theracide Plus
- Sani-Cloth (all)
Use the following procedure to disinfect system surfaces.
WARNING: Always use protective eyewear and gloves when cleaning and disinfecting any equipment.
Cautions:
- Use only recommended disinfectants on system surfaces. Immersion-type disinfectants are not tested for use on system surfaces.
- If you use an isopropyl alcohol solution for disinfection, ensure the solution is only 70% alcohol or less. Solutions of more than 70% alcohol can cause product damage.
To clean and disinfect system surfaces
1. Turn off the system and disconnect the system power cord from the wall outlet.
2. Use a soft cloth lightly dampened in a mild soap or detergent solution to clean exterior surfaces on the system.
3. Mix the disinfection solution compatible with your system (see the list above) according to label instructions for solution strength.
Caution: Do not spray disinfectant directly on system surfaces. Doing so may cause disinfectant to leak into the system, damaging the system and voiding the warranty.
4. Wipe system surfaces with the disinfectant, following disinfectant label instructions for wipe durations, solution strengths, and disinfectant contact duration. Ensure the solution strength and duration of contact are appropriate for the intended clinical application.
5. Air dry or towel dry with a sterile cloth according to the instructions on the disinfectant label.
Because the system is a piece of medical equipment that contains several circuit boards, extensive service diagnostics, and complex operating software, Philips recommends that only trained personnel service the system.

Maintaining the System Control Panel
The system control panel and other outer surfaces are most likely to be affected by liquid spills and other materials such as excessive amounts of gel. These materials may seep into electrical components under the panel and cause intermittent failures. During preventive maintenance, look for such potential problems including loose knobs and worn controls.
Regularly clean the outside of the system as described in Cleaning the System and ECG Equipment.

Cleaning the Trackball
Cleaning the trackball regularly prolongs its useful life and prevents service calls.
To clean the trackball
1. With your fingers, unscrew the ring around the trackball.
2. Put your finger in the access hole underneath the trackball, and push the trackball up.
3. Clean the trackball and the mounting area with a lint-free cloth or a small brush.
4. Place the ball back on the mounting area.
5. With your fingers, screw the ring back on.
