◎ About GPS 

●Global Positioning System, GPS is a system that developed and managed by the United States Department of Defense. The system consists of

    24 GPS satellites. Only 3 of which are needed in order to provide accurate positioning, speed detection and high precision time for most

    locations. The more satellites received, the more accurate each location will be decoded.

●Positioning accuracy control and system functions: due to policy consideration and national security, the U.S. reserves the right to

    control the systems functions and positioning accuracy without advanced notice or any notification at all.  Weather conditions, as well as, 

    environment and terrain will affect normal reception of satellite signal.

●Satellite signal cannot be received in the following environmental and terrain conditions:  at the bottom of hills, tunnels, underpasses,

    between high buildings and in dense forests.

This product  only functions with DC 12 V. 

Any damages caused by faulty installation shall be imputed to the users.

To avoid a short circuit from occuring, do not pull or modify the wires during installation.

Disassembling the instrument will void any warranty. Maintenance and repairs should be executed by our professionals only.
