PROXIMITY OF THE TMTS (TRANSMITTERS) AND i750TC
The TMTs emit low frequency signals that radiate out in semicircular patterns parallel to the length dimension of
the TMT. A coiled antenna inside the i750TC wrist unit receives the signals when it is positioned within a zone
parallel to or at a 45 degree angle to the TMT as illustrated.
The i750TC cannot effectively receive a signal when it is held out to the sides of the TMT or held at distances
greater than 0.91 m (3 ft) in front of the TMT. Best reception is achieved when the i750TC is within less than 0.91
m (3 ft) of the TMT.
When installed into the high pressure ports of the regulator first stages, the TMTs must be positioned so that they
face horizontally outward from the tank valves.
