Viamo SSA-640A Quick Guide

1 Daily Inspection (System Maintenance)

To ensure the safety of the system, it is the customer's responsibility to perform the following daily inspection and periodic inspection before/after operation. If an abnormality is found after inspection, the system must not be used. Contact your Toshiba representative. YEM55700Q-3

Daily inspection (including the pole-cart and peripheral devices and others)

Maintenance and inspection

Consumable parts list

[Inspection before and after an examination]

Occasional maintenance is performed by customers and periodic inspection is performed by service engineers. In this system, there is a maintenance menu that supports customer maintenance management. Refer to sections 7 "Daily Inspection" and 19 "Maintenance" of the operation manual <<Fundamentals Volume>> for details.

There are several consumable parts other than those in the list. Contact your Toshiba representative for details.

● Inspection before turning ON the system

No. 1 2 3 4 5 6 7 8 9

Inspection item Ambient temperature, relative humidity, and atmospheric pressure should meet the system requirements. There should be no condensation. There should be no deformation, damage or dirt on the system or peripheral devices. There should be no wobbling or loosening of screws in the monitor, casters, transducer holder, or peripheral devices. The caster locks should function normally. There should be no damage to the power cable or looseness of the connector. There should be no dirt and abnormality (projection, cracking, chasm, or peeling) in the appearance of the surface of the transducer, cable, or connector. There should be no foreign matter (clips etc.) on the main panel. There should be nothing blocking the air vent of the system, and no obstacles near moving parts.

● Inspection after turning ON the system

No. 1 2 3 4 5 6 7 8

9

Inspection item The transducer displayed on the system must match the connected transducer. There should be no abnormal noise, smell, or excessive heat generation. There should be no error messages. There should be no abnormal noise, discontinuous display, or dark area in 2D mode images. There should be no abnormality in the date and time display. The acoustic lens of the transducer should not generate excessive heat. (Touch the acoustic lens to check the temperature.) The switches and knobs on the control panel should function normally. There should be no color or display location abnormality in images that are output to a printer or recording device. (Inspect the image recording in advance before performing measurement using recorded images.) The DICOM communication should operate normally. (Perform communication inspection before performing DICOM communication.)

Failure handling If an image is not displayed even though the system is turned ON, or an ultrasound image is not displayed even though the characters are displayed, check the following items before judging it abnormal.

Phenomenon

Confirmation item

The system cannot be turned ON.

・ Confirm that the battery pack, power cable, and AC adaptor are connected. Confirm that connections to the outlet are normal. Also confirm that the battery has not run out of power.

Nothing is displayed (the contrast is too low or high) even though the system is turned ON.

・Confirm the brightness and contrast using the switches on the monitor.

An ultrasound image is not displayed, even though characters are displayed.

・ Confirm the settings for ACOUSTIC POWER, GAIN, and STC. ・ Confirm whether the transducer is connected normally. ・ Confirm whether the abnormality will be cleared if another transducer is connected.

[Recommended Settings] Bright room under white fluorescent lights (operating room, wards etc.): Brightness → 100、Contrast → 30 Indirect lighting room (bright examination room etc.): Brightness → 70、Contrast → 30 Dark room (dark examination room etc.): Brightness → 40、Contrast → 30 Adjust the settings according to the brightness of the room.

If an abnormality is found after inspection, contact your Toshiba representative.
