nications interface can be used to upload a new firmware version to
the device–this resets the device to its factory settings, which results
in the deletion of the former configuration. Instructions on firmware
uploads via the serial configuration interface are available in the LCOS
reference manual.
Boot only: A press of the button prompts a restart, regardless of how
long the it is held down.
Reset-or-boot (standard setting): Press the button briefly to restart
the device. Pressing the button for 5 seconds or longer restarts the
device and resets the configuration to its factory settings. All LEDs on
the device light up continuously. Once the switch is released the
device will restart with the restored factory settings.
This hard reset causes the device to start with the default factory set-
tings; all previous settings are lost!
Note that resetting the device leads to a loss on the WLAN encryption
settings within the device and that the default WEP key is active
again.

Hardware installation
The installation of the LANCOM Wireless Router takes place in the following
steps:
햲
Antennas
– Screw on the both included diversity antennas at the back of
the LANCOM 3850 UMTS access point.
Antennas are only to be attached or changed when the device is
switched off. Mounting or demounting antennas while the device
switched on may cause the destruction of the WLAN module!
If the reverse SMA antennas are attached to the device directly, the
quality of data transfer may be compromised if the internal WLAN
module and an external WLAN card in the cardbus slot (e.g.
AirLancer) are operated in the same frequency band at once. In this
situation, at least one of the wireless modules should be operated
with an external antenna.
