The position of the satellite can then be recalled at any time by simply entering this number. What's remarkable about this system is its positioning accuracy of 0.1 degrees. A manual key allows the unit to scan across the arc so that new satellites can be found. In the test department it only took us 30 minutes to complete the installation of the RT 140. The finish of the exterior unit is first class, with all components being manufactured from rust free materials.
Installation is straightforward and well documented.
