FAQ
Q:How to turn off voice broadcast of receiver?
A:a. Enter the WEBUI, find the voice switch in the settings page
and turn it off.
b. Controller Software→Device→Device Setting, turn off the “enable
voice”, and click “OK”.
Q:Can the base station and rover station be interchangeable?
A:The difference between the rover station and the base station is
that the accessories are different, the function and hardware
configuration are the same. You can use the controller to choose
the working mode of the device and set it as the base station or
rover station.
Q:What is CORS?
A:CORS is called a continuous operating reference station system.
It can be understood as a bas e station that is erected at a fixed
known point and works continuously for 24 hours, and sends its own
data to a specific serverthrough the network. The use of CORS
operation eliminates the need for a base station, and CORS is
equivalent to a base station in a normalnetwork operation.
