1) Mainboard should already have two metal spacers mounted on it. If it does not, please request them from the manufacturer.

2) Place the LTE modem above the metal spacers and male pin strips located on the mainboard. Gently push the modem board downwards so that:

   a) Male pin strip on the mainboard (3pins) inserts into Female pin socket on LTE board (3pincs)

   b) Male pin strip on the mainboard (7pins) inserts into Female pin socket on LTE board (7pincs)

   c) Male pin strip on the mainboard (2pins) inserts into Female pin socket on LTE board (2pincs)

   d) Two holes on the modem board are located directly above metal spacers and the modem board touches metal spacers.

3) Screw two M3 screws supplied with the modem through the holes into metal spacers as shown in the picture.

4) Insert antenna wires into a hexagon mounting hole located at the front or the back of the unit (e.g. VT335 has a front hole SMA only)

The antenna wire should now stick out to the front or to the rear of the unit (e.g. VT335 has a front hole) just like shown in the picture. Do the following for both main and auxiliary antennas:

1. Put a washer on the end of the antenna wire thread.

2. Screw the nut onto the antenna wire thread to the maximum with your hands.

3. Now use a wrench to tighten the nut

4. Screw the antenna to the end of the antenna wire thread.
