PROXIMITY of the TMTS (Transmitters) to the ATOM 3.0
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 ATOM receives the signals when it is positioned within a zone parallel to or at a 45 degree angle to the TMT
as illustrated.
The ATOM cannot effectively receive a signal when it is held out to the sides of the TMT or held at distances greater than 4 feet
(1.2 meters) in front of the TMT. Best reception is achieved when the ATOM is within 3 feet (1 meter) of the TMT.
When installed into the high pressure ports of the Regulator First Stages, the TMTs must be positioned so that they face horizon-
tally outward from the Tank Valves.
Link Interruption Underwater
During a dive, you may at times move the ATOM 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 ATOM is moved back into its correct position.
An interruption may also occur while the ATOM is within 3 feet (1 meter) of a running DPV. The Link will be restored within 4
seconds after the ATOM is moved out of that area.
A temporary interruption may also occur shortly after a Strobe flashes. The Link will be restored within 4 seconds.
If the Link is not restored within 15 seconds, the Audible will sound, and the Pressure value and Link icon will flash (Fig. 82).
