Proximity Of The Transmitters And I770R - Aqua Lung i770R Owner's Manual

DIVE FEATURES
PROXIMITY OF THE TMTS (TRANSMITTERS) AND i770R
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 i770R wrist unit receives the signals when it is positioned within a zone par-
allel to or at a 45 degree angle to the TMT as illustrated.
The i770R 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 i770R 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.
Link Interruption Underwater
During a dive, you may at times move the i770R 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 i770R is moved back into its correct position.
An interruption may also occur while the i770R 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 i770R is moved out of that area.
If the link is not restored within 1 minute, the audible alarm will sound, dashes will replace gas pressure and GTR
values.
