Receiver Unit 

The Receiver Unit receives and processes the noise data from the radio transmitters and then transmits the data via Wi-

Fi 

to 

a Tablet running the 

EUREKA GO

 

App 

to produce a leak noise correlation

.

 

3.3.1

 

Antenna Socket

 

The antenna TNC socket allows the connection of one of the three supplied antenna that are stored in the transport case

.

 

3.3.2

 

On/Off Push Button Switch

 

The on/off push button switch (B in the photo) has several functions: 

When the Receiver is off: 

A single press of the button will start the power on process. At this point the Power LED will turn on. Approximately 90 

seconds later the Wi-

Fi Status LED will start to flash fast and intermittently. The unit is not fully powered until the Wi

-

Fi 

Status LED is flashing slowly & steadily. This indicates that the Wi

-

Fi is trying to connect to the tablet.

When the Receiver is on: 

Two 

quick presses of the button will start the power down process. The Wi

-

Fi Status LED will flash fast and steady 

for a

few seconds and then 

the Power LED will turn off. The unit is now powered down.

Pressing and holding the button 

for longer than 6 seconds will cause a forced power

-

down and reset the unit. This

operation should be avoided as it can limit the life of the internal memory card.
