Transmitter Control
– This feature is used to control a transmitter with the Radio Link activated remotely. For more
information, see the section “Remote Operation of the transmitter.”
DFT
– Discrete Fourier Transform is a tool to help choose a frequency to apply to the target conductor. The DFT feature will aid
the user with nearby interference that may a󰀨ect the locate quality.
Cloud
– This menu item ties the VMMap Cloud-based app to the RTK-Pro unit. Use this menu item to check the Cloud connection
status. To use the Vivax-Metrotech Cloud-based VMMap app setup an account and register each locator that will use the app.

Satellite Information
– Enter this menu item to show all current satellite information.
2.5 Self-Test
The self-test feature must be run in an area free from interference, such as overhead uorescent lighting, large transformers,
etc. Also, check that any nearby transmitters or sondes are switched o󰀨.
Select “Self-Test” from the user menu and press the “Return” button. Keep the receiver stationary while the test is running. After

Examples of the self-test results
If the receiver fails the test, try again in an area with less interference. If it continues to fail, return the unit to Vivax-Metrotech or
one of its approved repair centers for investigation.
