1. A portable device for testing an EOT unit of a two-way EOT radio telemetry system, such EOT unit capable of (A) transmitting (i) authorization signals relevant to an arming procedure for such two-way EOT system and (ii) data signals indicative of operational data for an apparatus to which such EOT unit is connected and (B) responding to (i) a status update request during such arming procedure and (ii) brake signals by reducing pressure in a volume to which such apparatus is connected;

  • said portable device comprising;

    (a) a means for authorizing said portable device to communicate with such EOT unit according to such arming procedure;

    (b) a means for initiating an emergency reduction in pressure in such volume, said emergency initiating means being activatible only upon authorization of said portable device;
