KOWA is a medical electrical instrument. The medical electrical instrument requires special care concern-
ing electromagnetic compatibility (EMC). This section describes its suitability in terms of electromagnetic compatibil-
ity of this instrument. When installing or using this instrument, please read carefully and observe what is described
here.
(This instrument was tested on electromagnetic compatibility (EMC) based on IEC 60601-1-2.)
1. Carefully handle portable- or mobile-type radio frequency communication unit (RF communications equip-
ment) since it may have an adverse effect on this instrument resulting in malfunctioning.
2. This instrument was tested on electromagnetic compatibility (EMC) with optional or accessory parts being
assembled into it.
Do not assemble into this instrument any optional or accessory parts other than those designated by
Kowa. Otherwise, this instrument may be adversely affected by other instrument resulting in malfunction-
ing, or the latter itself may malfunction.
• Power cable (a maximum length of 3 m)
• Video Adapters made by Kowa
• Dedicated synchronous cables (a maximum length of 5m)
• Cameras with CE marking
3. This instrument is not designed such that it can be used adjacent to other instrument or placing one on top
of another. Therefore, do not apply such use. Nevertheless, if such use is inevitable, it is necessary to con-
stantly monitor if the instrument is functioning normally after such use has been adopted.
