Specifications

This will prevent slow leakage of air, which will reduce the holding
power of the suction cups over time. It will also protect the painted
surface.
If the surface of the vehicle is very rough, the installation procedure
remains the same. The suction cup will have to be pressed against the
vehicle surface in the same way, but more lubricant may be necessary.
Tightening the QMS Straps. The QMS enclosure must be tightly
strapped to the vehicle. To ensure it is properly strapped, grab the base
of the antenna mounted on the QMS and push firmly up and down. The
vehicle should move up and down, but the QMS should not. If the QMS
moves and the vehicle does not, increase the tension on the QMS straps.
Removing the QMS. Wash the vehicle in the area around the suction
cups before removing. This will reduce any chance of surface marring.
• Release suction by applying a rolling sideways motion to the tabs
on the suction cups as shown in the following drawing:
