Seeker & Seeker MCA III Operation Manual
Squelch Operation
Squelch level is the RF signal threshold that the Seeker uses to determine the validity of
the signal. The signal “breaks squelch” when the RF leakage is greater than the squelch
level,aslongasanyenabledtagorGTnoisequaliersaremetaswell.Thereceiverwill

Source Localization
The Seeker emits an audible tone to help the user pinpoint the leakage source. The
tone frequency increases with signal strength. As the user moves closer to the leak, the
frequency of the tone will increase.
Vehicle Battery Protection
Overview
The Mobile Mount and Mobile Communications Adapter (MCA III) are equipped with
circuitry which automatically powers down the MCA III when the vehicle’s ignition is
turned off, only after all data upload processes have been completed. This feature
allows the vehicle to be parked and left unattended for long periods of time without
concern for depleting the vehicle’s battery. Mobile Mounts and MCA IIIs which feature
batteryprotectioncircuitryareidentiedwitha“GreenEngineering”logoonthedevice.
This feature allows a vehicle equipped with the “Green Engineering” Mobile Mount and
“Green Engineering” MCA III to automatically upload leakage data to the LAW server
application while parked and left unattended. Upon completion of the data upload
(or after a user-programmed number of attempts to upload data), the MCA III will
automatically power down. The MCA III will also stay on for a selectable time period to
avoid any “cold start” delay required by the GPS receiver after a power down.
Common leakage areas are around the tap, drop cable, and
any connection of the cable to other devices.
