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.
