B Wireless LAN
The system provides wireless net adapter configuration, so as to assist information query and
unlimited network service.
• 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.
• For a better wireless LAN transmission effect, please take the following settings:
– SSID>80% with stable WLAN network;
– Wireless router and the server are in the same network segment;
– Router setting:
Wireless standard 802.11n
Maximum transmission speed ≥300M
Use AP (access point) setting;
Number of the devices connected to the same router ≤5.
– Target server setting:
Network is stable and not under overloading state (e.g. high CPU/memory usage, fast
HDD speed, limited HDD space);
Level other than the highest level of firewall is adopted;
Operating system is Win8 or higher versions and 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 IEC60601-1-2:2014 standard.
