3.4.3 Network Verification Process
This part is completed through two ways: First the hospital completes items requiring self-check of the hospital’s IT
Dept, as indicated in the Network Verification Table. Then customer service personnel or authorized party confirms items
on site and finally completes the Network Acceptance Table. If any item is found incompliant during network Verification
test, adjustment should be made before the patient monitors installation.
When in test, the Wi-Fi network SSID broadcast needs to be enabled to ensure that the Wi-Fi SSID can be scanned.
