Wireless LAN D-1
Appendix D Wireless LAN
The system provides wireless net adapter configuration, so as to assist information query and
unlimited network service.
WARNING
It is prohibited to use the wireless LAN function in an airplane, as
this may violate the relevant provisions in the aviation
regulations.
Use the wireless LAN function prudently in emergency
ambulances (or other vehicles) as other devices or
communication signals may be interfered with.
Use the wireless LAN function prudently in OR/ICU/CCU as it may
interfere with other devices.
When the wireless LAN function is turned on, the ultrasound
system may suffer interference from other equipment, even if
that other equipment complies with CISPR EMISSION
requirements.
Keep at least 20 cm away from the ultrasound system when the
wireless LAN function is in use.
NOTE:
For a better wireless LAN transmission effect, please take the following settings:
z
SSID>80% with stable WLAN network;
z
Wireless router and the server are in the same network segment;
z
Router setting:
h
Wireless standard 802.11n
h
Maximum transmission speed
≥
300M
h
Use AP (access point) setting;
h
Number of the devices connected to the same router
≤
5.
z
Target server setting:
h
Network is stable and not under overloading state (e.g. high
CPU/memory usage, fast HDD speed, limited HDD space);
h
Level other than the highest level of firewall is adopted;
h
Operating system is Win8 or higher versions and it supports a Gigabit
Ethernet.
Disconnection may be caused if the devices connected excess the router capacity
(please refer to settings of the router, generally it should be
≤
5.)
DO NOT connect devices other than specified into the LAN.
Medical devices within the same LAN may interfere with each other, the operator
should be cautious. (Do not connect devices that may cause strong interference. For
example, life-supporting devices should not be connected in the same LAN.)
Other non-medical devices in the same frequency band may cause interference,
please be cautious.
Wi-Fi function is not affected when the system is imposed with radiation interference complied
with IEC60601-1-2:2007 standard. See 12.5 Network Preset for the operation of WiFi in detail.
