Manual Reference
GE LOGIQ e / LOGIQ e Vet / LOGIQ i / Vivid e Basic Service Manual, Part Number 5370626-100, Revision 18. The manual covers LOGIQ e software versions R4.x.x through R7.x.x.
Manufacturer Recommendation / AEM Status
GE states that engineering determined the LOGIQ e / LOGIQ e Vet / LOGIQ i / Vivid e system does not have high-wear components that fail with use, therefore Periodic Maintenance Inspections are not mandatory. The manual also states that some customer QA programs may require additional tasks or inspections at different frequencies.
The manufacturer-listed care schedule is presented as a reference schedule, not a mandatory PM schedule. The manual states that the schedule assumes average use of 10–12 patients per day and use as a primary mobile unit transported between diagnostic facilities. Increase maintenance frequency if use exceeds typical usage or patient load.
Manufacturer-listed Frequency Items
Clean probes: daily / before each use.
Inspect AC mains cable: weekly for mobile unit use.
Inspect cables and connectors: monthly.
Clean console: monthly.
Clean LCD: monthly.
Console leakage current checks: per facility QA program; table note lists twice annually.
Peripheral leakage current checks: per facility QA program; table note lists twice annually.
Surface probe leakage current checks: per facility QA program; table note lists twice annually.
Endocavity probe leakage current checks: per facility QA program. The table includes quarterly / annually wording, so this should be verified against the facility’s probe policy before building the CMMS interval.
Measurement accuracy checks: per facility QA program; table note lists twice annually.
AEM Note
If a facility performs this PM at a different interval or changes the listed activities, that should be handled under the facility’s approved AEM program, risk assessment, maintenance history, usage level, probe type, patient-care risk, and applicable regulatory requirements.
What This PM Procedure Covers
This procedure covers visual inspection of the console, AC adapter, cables, connectors, probes, and peripherals; power-on and battery operation checks; probe recognition; LCD/display check; basic ultrasound functional checks; measurement accuracy check; electrical safety testing per manual and facility policy; and documentation for CMMS/work order closure.
Required Tools and Equipment
Digital volt meter.
Anti-static kit.
Anti-static vacuum cleaner.
Safety analyzer, GE listed Part Number 46-285652G1, calibrated and compliant with AAMI/ESI 1993, IEC 60601, or AS/NZS 3551.
QIQ Phantom E8370RB, RMI Grayscale Target Model 403GS.

Facility-policy-dependent items may include an outlet tester, ground continuity / protective earth test setup if required by facility PM policy, and probe leakage test adapters or accessories required by the facility’s ultrasound/probe safety program.
Step-by-Step PM Procedure
1. Confirm Device Status and User Concerns
Ask the user or department if there are image quality issues, intermittent power issues, probe problems, battery concerns, boot errors, or workflow complaints.
Expected outcome: Any known issue is documented before PM testing starts.
Why it matters: The manual’s preliminary checks include “Ask & Listen” as the first system check.
2. Identify System, Probes, and Options
Record the asset number, serial number, software version if needed, installed probes, peripherals, and system options.
Expected outcome: PM documentation matches the actual system configuration.
3. Visual Inspection
Inspect the console housing, LCD and hinge area, keyboard/control panel, AC adapter and mains cable, DC input connector, probe connectors, probe housings, probe lenses, strain reliefs, probe cables, USB peripherals, printer, ECG module, footswitch, wireless adapter, and other accessories if present.
Expected outcome: No cracked probe, damaged cable, broken connector, exposed conductor, damaged enclosure, missing cover, loose hardware, contamination, or unsafe accessory is found.
Remove from service if: A probe is cracked, damaged, dropped and suspect, leaking, has exposed wiring, has failed leakage testing, or the console, adapter, cable, or accessory shows electrical or mechanical damage. The manual warns not to use damaged or defective probes.
4. Power-On Check on AC Power
Connect the AC adapter to a properly grounded outlet. Power the system on.
Expected outcome: The system boots normally, no warning or error messages appear during startup, fans/peripherals power on as expected, and battery charging indication is present if a battery is installed.
The manual’s preliminary checks include powering up with AC input, verifying fans and peripherals turn on, watching for warning/error messages, and checking battery recharging.
5. Battery Operation Check
Disconnect AC power and verify the system operates on internal battery.
Expected outcome: The system remains powered and operates on battery without immediate shutdown or abnormal warning.
The manual lists checking operation without AC input using the internal battery as part of preliminary checks.
6. Probe Recognition Check
Connect each probe assigned to the system. Verify each probe is recognized by the system.
Expected outcome: All assigned probes are detected correctly.
Remove from service if: A probe is not recognized after reseating/inspection, has physical damage, or fails leakage testing.
7. LCD / Display Check
Verify the LCD displays properly during normal operation.
Expected outcome: Display is readable, stable, and free of major defects that would interfere with clinical use.
8. Functional Imaging Checks
Perform basic functional checks using an appropriate probe and phantom/test object.
Verify B-Mode operation, Color Flow Mode operation, Doppler mode operation if available, M-Mode operation, applicable software options, keyboard/control operation, and LCD/software menu display functions.
Expected outcome: Imaging modes and controls respond normally with no obvious system malfunction.
9. Measurement Accuracy Check
In measurement mode, make a distance measurement and verify the result against a graduated rule or phantom reference.
Expected outcome: Distance accuracy is within ±5%, as listed in the manual’s system functional checks.

10. Cleaning Check
Verify console, LCD, probes, and accessories are clean. Clean only according to approved facility and manufacturer cleaning practices.
Expected outcome: Device is visibly clean and ready for use.
Probe cleaning before use is listed in the manufacturer care schedule.
Electrical Safety Testing
The manual’s electrical safety section is based on IEC 60601-1 and states to test the system, peripherals, and probes for leakage current. It also states not to use probes or equipment with excessive leakage current.
The manual states safety inspections must be performed at least every 12 months according to IEC-EN 60601-1 and only trained persons are allowed to perform them.
Outlet / Wiring Check
Test the outlet used for the ultrasound system for proper grounding and wiring arrangement.
Expected outcome: Outlet passes facility electrical safety criteria.
Do not use outlet if: Grounding or wiring abnormality is found. The manual says problems should be reported to the hospital immediately and the receptacle should not be used.
Ground Resistance / Protective Earth Documentation
The provided manual does not list a specific ground resistance pass/fail value in the retrieved PM section. Use facility/NFPA 99 criteria if your facility requires this measurement.
Ground resistance measured in ohms, expected ≤ 0.5 Ω or facility/NFPA 99 criteria if different.
