DATE EDIT – (ON/OFF)
This selects whether the date is displayed or not
TIME EDIT – (OFF/+0 to +12/-1 to -12)
As the time display is taken from the GPS satellite (it is always accurate to within 1 second),
you may have to apply an offset so it is displayed correctly for your time zone. For example,
UK British Summer Time would require an offset of +1. If you do not want the time to be
displayed, select ‘OFF’.
SPEED EDIT – (MPH/KPH/OFF)
Selects units of measurement for speed, or no speed display. Speed is measured from the GPS
position information and is accurate to <1mph. Please note that most vehicle speedometers
are designed to ‘over-read’ by 5-10%, so the RT800 speed displayed will not necessarily match
your vehicle’s speedometer.
LAT/LON EDIT – (ON/OFF)
Selects whether positional information (latitude and longitude) is displayed or not.
ALTITUDE EDIT – (METRES/FEET/OFF)
Selects units of measurement for altitude display or turns this display off. The accuracy of
altitude readings derived from GPS signals is dependant on the number of satellites in view of
the antenna. In built-up areas the altitude displayed may change even when the vehicle is not
moving. This is because satellites are moving in and out of view and the receiver is constantly
re-calculating the data. For this reason, the accuracy of the altitude figure is likely to be +or-3
to 5 metres most of the time. Better accuracy would be obtained in a wide open space, up a
mountain or in an aircraft where more satellites are in view for more of the time.
BACKGND EDIT – (OFF/ON)
The on-screen text can be displayed on a black background by turning this feature on.
POSITION EDIT
This allows you to position the data displayed in one of four on-screen locations: Top left
corner, top right corner, bottom left or bottom right.
