Avoid using the unit directly after strong temperature changes.
If the unit is exposed to strong temperature and humidity fluctuations, condensation can

has dried off before using the unit.
NOTE: If you bring the unit from a cold to a warm environment, or vice versa, first let it
get accustomed to the new temperature before turning it on.
2. Starting operation
Plug the USB cable in a free USB port on your notebook etc. The NL-662U will be
recognized by your Windows operating system, which will attempt to install a driver.
Abort this process, and start “u-center_7.xx_Installer.exe” from the CD-ROM, or
download the driver from the Navilock website at
http://www.navilock.de/produkte/F_779_GLONASS_61973/software.html.
Follow the installation instructions. After the installation is completed, re-start your
computer. Then the GPS COM port will be available in the Device Manager under
Connections. Set this port in your navigation or route planner software. Do not use
another program that accesses this port at the same time.
