Troubleshooting
Problem Cause Remedy
Poor reception
despite available
UMTS connection . The device is not switched
ON [Status LED OFF). Switch device ON
Check plug-in power supply
The connections antenna
input and UMTS terminal
interchanged during installation. Check installation,
correct if necessary
Using an external antenna,
it might be not directed to
the base station correctly. Align the external antenna,
fi nd the best position by using
the fi eld strength indicator of
your connection software.
