DTU breaks down, please contact your
distributor for maintenance. Opening the DTU
without permission will invalidate the warranty.

placed at least 1 meter above the ground and
try to install the DTU 90 degrees vertical to the
ground as much as possible (figure 3).

Note: Please do not install the DTU direct above the
metal or concrete to prevent the signal dilution.

Once the DTU powers on, the red, green and blue
lights will flash for one second in turns for 30
seconds.

or tablet) to search the surrounding WiFi signal,
you can find the DTU’s WiFi named as “USR-
