1. Poor Reception Area Poor Reception Area Poor Reception Area Poor Reception Area Transmitter Signal Reception Guide POSITIONING OF THE VT3 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 VT3 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 76 The VT3 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 VT3 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 VT3 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 Audible Alarm to sound and message TMTx gt LINK gt LOST to scroll Fig 61 The Link will be restored within 4 seconds after the VT3 is moved back into its correct position NITROX FT EZ Fig 61 Link Interruption Underwater 77 DTR NDC No Deco BN NITROX
