2 vLoc3 RTK-Pro Receiver
2.7.3 Set up the RTK settings in the Locator
It should now be possible to start using the locator, but rst, a few locator settings need to be set.
1. Switch on the locator and enter the user settings by using a long press of the info
key.
2. Scroll to the “About” option and press the return key. A screen similar to this will
appear:

O2-UK LTE
There may be a message “Cellular Module searching” shown for a few seconds. This is normal, as the module takes a few
seconds to boot up. The two critical items in the about screen are:
• Cellular SIM
Ready.
• Cellular Network (the tick shows a data connection is made, the LTE indicates a 4G LTE data connection is made). This
confirms the SIM card is detected and active. Instead of showing O2 etc., it will show your cellular provider.
If the Cellular module is active, this screen will be made available in the user set up
menu. Initially, it will show “RTK source,” “None,” and “RTCM status,” “No Network.”
Once a cellular network data connection has been made, it will show “RTCM status”
“Waiting.”
With the “Get RTK sources” highlighted, press “Enter” to ask the locator RTK to request
the list of available RTK correction sources from the congured NTRIP caster.

Scroll to the source you wish to use and press the enter key to select.
“RTCM status” will show “Waiting,” then
“Connecting,” then
“Requesting RTCM,” then
“Receiving RTCM” as the locator receives RTCM from the NTRIP caster.
In this case, the “RTK source” shows the selected RTK source “RTK_MSM5.”
