10-5-7 Probe Maintenance
10-5-7-1 Probe Related Checks
 
10-5-7-2 Basic Probe CareThe system user manuals and various probe handling cards provide a complete description of probe 
care, maintenance, cleaning and disinfection. Ensure that you are completely familiar with the proper 
care of GE probes.
Ultrasound probes can be easily damaged by improper handling. See the User Manual and probe care 
cards for more details. Failure to follow these precautions can result in serious injury and equipment 
damage. Failure to properly handle or maintain a probe may also void its warranty.
Any evidence of wear indicates the probe cannot be used.
Do a visual check of the probe pins and system sockets before plugging in a probe.
TEE and Interoperative probes often have special considerations and individual probe user manuals. 
For TEE and Interoperative probes also refer to their separate user manuals.
10-5-7-3 Basic Probe Cleaning Refer to the User’s Manual for details on probe cleaning.
NOTE: To help protect yourself from blood borne diseases, wear approved disposable gloves. These are made  of nitrile derived from vegetable starch to prevent allergic latex reactions.
NOTE: Failure to follow the prescribed cleaning or disinfection procedures will void the probe’s  warranty. DO NOT soak or wipe the lens with any product not listed in the User Manual. Doing 
so could result in irreparable damage to the probe. Follow care instructions that came with the 
probe.
NOTE: Disinfect a defective probe before you return it. Be sure to tag the probe as being disinfected.

10-12Section 10-7 - Electrical Safety Tests
Section 10-7
Electrical Safety Tests
10-7-1 Safety Test Overview
The electrical safety tests in this section are based on and conform to NFPA 99 (For USA) and IEC 
60601-1 Medical Equipment Safety Standards. They are intended for the electrical safety evaluation of 
cord-connected, electrically operated, patient care equipment. If additional information is needed, refer 
to the NFPA 99 (For USA) and IEC 60601-1 documents.
 
Test the system, peripherals and probes for leakage current. Excessive leakage current can cause 
injury or death in sensitive patients. High leakage current can also indicate degradation of insulation and 
a potential for electrical failure. Do not use probes or equipment having excessive leakage current.
To minimize the risk that a probe may shock someone the customer should:
• Not use a probe that is cracked or damaged in any way
• Check probe leakage current:
* once a year on surface probes
* twice a year on endocavitary probes
* whenever probe damage is suspected
WARNINGWARNINGTHE USER MUST ENSURE THAT THE SAFETY INSPECTIONS ARE PERFORMED AT 
LEAST EVERY 12 MONTHS ACCORDING TO THE REQUIREMENTS OF THE PATIENT 
SAFETY STANDARD IEC-EN 60601-1. ONLY TRAINED PERSONS ARE ALLOWED TO 
PERFORM THE SAFETY INSPECTIONS MENTIONED ABOVE.
CAUTIONTo avoid electrical shock, the unit under test must not be connected to other electrical 
equipment. Remove all interconnecting cables and wires. The unit under test must not be 
contacted by users or patients while performing these tests.
CAUTIONPossible risk of infection. Do not handle soiled or contaminated probes and other components 
that have been in patient contact. Follow appropriate cleaning and disinfecting procedures 
before handling the equipment.
