Wireless LAN
The system provides wireless net adapter configuration, so as to assist information query and
unlimited network service. The ultrasound system can be connected to router, mobile phone, tablet,
ultrasound workstation, server network device and so on via wireless network.
• 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 Linux 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.
