Let's Get Started - Motorola ML1500 Quick Start Manual

Let's get started

First attach the 2 LTE Antennas to the ML1500 by screwing
them finger-tight into the 2 gold connectors located on the
back of the unit. The best orientation for these antenna varies
by location but is normally half way between horizontal and
vertical.
Next connect the included yellow Ethernet cable between the
ML1500's Ethernet port and the Ethernet port of your
computer, router, or other Ethernet-capable device.
If you are using your ML1500 with a wireless router, we will
explain how to configure the ML1500 for a router later in this
Quick Start.
