Understanding the Electronics of the NVR750c 

 
Your new Navigator NVR750c uses a highly sophisticated and patented electronic gyroscope as 
the navigation system to steer the buggy when in ‘Nav On’ mode.  The gyroscope is tilt 
compensated to enable true steering over a wide range of grades, which you could expect to 
encounter on the average golf course. 
 
Your new NVR750c with electronic gyroscope motor controller will allow the navigation system to 
operate at the desired handle height independent of any external conditions. 
 
Your NVR750c employs auto range detection, so the buggy will not go out of range of the remote 
control.  A battery saving feature has also been added to the operation of your remote control.  If 
some reason you do not touch the remote control for two minutes whilst your buggy is within 
range, the buggy will stop. Simply press a command on the remote and the buggy will resume 
whatever task you seek of it. 
 
See Point 17 for understanding ‘Nav On’ and ‘Nav Off’.
