2.6.2 Powering the Low Frequency Transmitter and Receiver
Turn the transmitter and receiver ON by pressing the button on the top of each unit. The red Power LED on
the top of the unit will flash 5 times and then stay on to indicate the unit is ready for operation. If not, check
that the batteries inside the Transmitter and Receiver are fully charged and have been inserted the right
way.
When not collecting data, the transmitter and receiver should be turned OFF to increase the life of the
batteries.
2.6.3 Digital Video Logger
Once all the cable connections are made between the control module, transmitter, receiver, the Digital
Video Logger (DVL) and the battery, the upper red LED light on the DVL panel should be lit. If the battery
voltage is too low, the LED light will flash for about 30 seconds and go out. If the light flashes or does not
appear, check the connections and make sure the battery is fully charged.
The low voltage indicator can be helpful for identifying when the battery needs to be recharged. If the
battery voltage drops too low the DVL will cease to operate.
The front of the DVL is shown in Figure 2-35. To start the system, press any button on the front panel. The
DVL will begin to beep indicating it is booting up. The lower red LED on the front panel should illuminate.

The water-resistant membrane keypad has a number of buttons that can be pressed to perform various
tasks.
Menu Buttons: The buttons labelled 1 to 8 correspond to menu choices that appear listed on the screen or
along the bottom of the screen when the Digital Video Logger is turned on.
In addition, there are two general-purpose buttons labelled A and B. All buttons are DVL software
application dependent and roles change. The operation will be self-explanatory from the display screen.
Screen: The DVL screen is a grey scale LCD selected for its wide temperature range and visibility in
sunlight. Visibility can be a major problem with viewing GPR data displays outdoors and considerable effort
has been expended on getting a readily visible outdoor display.
