The i450T cannot effectively receive a signal when it is held out to the sides of the TMT or held at distances
greater than 3 feet (0.91 meters) in front of the TMT. Best reception is achieved when the i450T is within less than
3 feet (0.91 meterS) 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.
Link Interruption Underwater
During a dive, you may at times move the i450T out of the signal pattern of the TMT, resulting in a temporary loss
of the link signal. The link will be restored within 4 seconds after the i450T is moved back into its correct position.
An interruption may also occur while the i450T is within 3 feet (1 meter) of a running DPV, or shortly after a strobe
flashes. The link will be restored within 4 seconds after the i450T is moved out of that area.
If the link is not restored within 15 seconds, the audible alarm will sound, dashes will replace GTR and gas pres-
sure values, and the link icon will flash until it is restored.
PROXIMITY OF THE TMTS (TRANSMITTERS) AND i 450T
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 i450T wrist unit receives the signals when it is positioned within a zone paral-
lel to or at a 45 degree angle to the TMT as illustrated.
