12 About US40a Wireless LAN Features The wireless LAN features allow computers separated from one another to share data and programs and transfer messages among them. Notes on Use of Wireless LAN • The transmission speed and distance of wireless LAN vary depending on the used wireless LAN devices, circumferential conditions including radio wave, obstacles and installation environments. • The transmission speed of wireless LAN tends to be slower with longer communication distance due to the nature of radio wave. For more comfortable usage of wireless LAN, it is recommended to place wireless LAN devices within short distance. • The transmission speed and distance of wireless LAN (IEEE802.11b or IEEE802.11g) supported devices may decrease while using a microwave oven near by. It is recommended to use wireless LAN (IEEE802.11b or IEEE802.11g) supported devices away from microwave oven. • When wireless LAN (IEEE802.11b or IEEE802.11g) supported devices and Bluetooth supported devices are used simultaneously, the transmission speed and distance of devices may decrease. In such cases it is recommended to switch off either of the wireless LAN (IEEE802.11b or IEEE802.11g) devices and the Bluetooth supported devices or use by keeping distance between them. • To connect US40a to a network, an optional wireless LAN access point is required. • Turn off the power of US40a or switch off the wireless LAN feature in an area where medical authorities prohibit usage of this product. Moreover, even in the medical establishment where usage of this product has been allowed, either turn off the power or switch off the wireless LAN of this product when medical equipments are being used in near by. • During network communication, do not enter US40a into the standby and suspend states. • Network communication shortens the period in which US40a can be driven by the battery only. When communication for a long period is required, connect the AC adapter to US40a to supply power through an AC outlet. • In standby or suspend mode the network feature is disabled temporarily. Therefore put US40a into standby or suspend modes after completion of communication operations like file copy etc. Moreover, some application software lost data while US40a recovers from standby or suspend mode. While using applications which uses network, verify the same with the system administrator and use the standby or suspend mode appropriately.
About US40a 13 Notes on Security in Use of Wireless LAN Devices The wireless LAN can transfer data between a PC and a wireless access point through radio waves instead of using LAN cables. Accordingly, the wireless LAN is advantageous to enable free LAN connection within the area where radio waves can reach. On the other hand, the wireless LAN may cause the following problems to occur without proper security because radio waves can penetrate obstacles (including walls) to reach any places within a certain range. • Communication data is sniffed. Malicious third parties may intentionally intercept radio waves to sniff communication data as follow: – Personal information including user IDs, passwords and credit card numbers and – E-mails. • Network is invaded illegally. Malicious third parties may access to personal or corporate networks without permission to: – get out personal or confidential information (information leakage), – spoof as a specific person to distribute wrong information (spoofing), – intercept communication data, rewrite the data and send out the rewritten data (alteration) and – distribute computer virus to crack data and systems (cracking). Wireless LAN cards and access points essentially have security schemes to cope with these problems. Therefore, proper settings on security in wireless LAN devices can reduce the possibility at which these problems occur. It is recommended to be familiar with the problems in use of wireless LAN devices without security and provide proper security settings in your judgment and responsibility. If you cannot deal with security settings by yourself, contact your service representative. NEC does not assume any responsibility for any losses caused by problems occurred due to no security measures or unavoidable circumstances concerning wireless LAN specification.
