Link Interruption Underwater - Aeris Epic Operating Manual

POSITIONING OF THE EPIC
The Transmitters (TMTs) emit low frequency signals that radiate
outward in semicircular patterns that are parallel to the length
dimension of the TMT. A coiled antenna inside the PIC receives
the signals when it is positioned within a zone parallel to or at a
45 degree angle to the TMT as illustrated on page 92.
The PIC cannot effectively receive a signal when it is held out to
the sides of the TMT or held at distances greater than 6 feet (2
meters) in front of the TMT. Best reception is achieved when the
PIC 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 PIC out of the signal
pattern of the TMT, resulting in a temporary interruption of the
Link signal.
An interruption lasting greater than 15 seconds will cause the
Tank Pressure value to flash, the Link icon to flash, the Audible
Alarm to sound, and message TMTx > LINK > LOST to scroll
(Fig. 77). The Link will be restored within 4 seconds after the
PIC is moved back into its correct position.
