W ARNING!
CAREFULLY READ ALL THE WARNINGS LISTED BELOW!
1. The operator manual should be fully read and understood before operating the LOGIQ 400 and kept nearby for
quick reference.
2. Although the ultrasound energy transmitted from the LOGIQ 400 transducer is within AIUM/NEMA standards,
unnecessary exposure should be avoided. Only trained personnel should operate the LOGIQ 400.
3. T o prevent electrical shock, the LOGIQ 400 should be connected to a properly grounded power receptacle. Do
not use a three prong to two prong adapter. This defeats safety grounding.
4. Do not use with Defibrillator when LOGIQ 400 is being operated .
5. Probes are fragile, please handle with care.
6. Concerning Outside Markings, refer to Illustration 1–1, 1–2, 1–3, 1–4, 1–5, 1–6, and 1–7.
7. For the cleaning, disinfection, and sterilization, refer to Probe section in LOGIQ 400 User Manual and Caution
Sheet supplied with each probe.

1–3 EMC (Electromagnetic Compatibility)
1–3–1 EMC Performance
All types of electronic equipment may characteristically cause electromagnetic interference with other equipment,
either through air or connecting cables. The term EMC (Electromagnetic Compatibility) indicates capability of the
equipment, which curbs electromagnetic influence from other equipment and at the same time does not affect other
equipment with similar electromagnetic radiation from itself.
This product is designed to fully comply with the EN60601–1–2 (IEC601–1–2), in Medical electrical equipment EMC
regulations.
Proper installation following this service manual is required in order to achieve the full EMC performance of the product.
The product must be installed as stipulated in 1–3–2, Notice upon Installation of Product.
In case of issues related to EMC, please follow procedures stated in 1–3–4, Countermeasures against EMC-related
Issues.
1–3–2 Notice upon Installation of Product
1) Use either power supply cords provided by GEMS or ones designated by GEMS. Products equipped with
power source plug should be plugged into the fixed power socket which has the protective grounding conductor.
Connect a three-pole plug to a three-pole socket without using a three-pole-to-two-pole converter.
2) Locate the equipment as far as possible from other electronic equipment.
3) Be sure to use either any cables provided by GEMS or ones designated by GEYMS. Wire these cables follow-
ing these installation procedures.
(Example) Wire power cables separately from signal cables.
4) Lay out the main equipment and other peripherals following the installation procedures described in Chapter2,
INST ALLATION.
