GEONAUTE KEYMAZE 500, Documentation

Page: 49 / 53

The building at the end of the arrow is at the following UTM coordinate: 602.249 and 5327.226 in zone 30 U: it is 249 metres from line 602 and 226 metres from
line 5327.
Google Earth can display the location of a point in degrees-minutes-seconds, in degrees or in UTM.
3.1.3. Important information about the Keymaze
a) Design choice
As described above, GPS accuracy can be poor in some situations. The accuracy of the Keymaze will be between 10 and 30 metres. However, it can be
better.
You should also know that, even though it is stopped, the Keymaze will not display zero speed: this is normal, because at every moment the user's location
(measured by the device) is slightly different.
To measure speed, we have decided to allocate high accuracy to average speed, even if this means having a slightly delayed display.
As regards altitude, only an altimeter with a pressure sensor can provide the same accuracy. As the Earth is not a perfect sphere, geographers have determined
an average level for 0 metres altitude: the geoid (a representation of the earth's surface drawn to approximate as closely as possible the "real surface"). Altitude
refers to the distance of a point from the geoid.
b) Recommendations for effective use
Do not overestimate your physical capacities: if you have a Keymaze 700, use the cardiac function in order to work at the right energy level.
In terms of calories expended, you should set your Keymaze according to your activity type, and to set your personal settings carefully. The more accurate these
settings are, the closer the result will be to reality.
When you want to record a training session, set the trackpoint recording setting to a correct value. For long training sessions (lasting over an hour, for example),
it is not necessary to record points every second. Recording a point every 30 seconds may be enough. You will also save memory capacity.
In navigation mode, you should set the parameter allowing you to go from one point to another (SWITCH DISTANCE). The value of this parameter must be
adapted according to the speed with which you are travelling: the faster you go (on a bike for example), the higher this parameter will be. We advise you to enter
50 metres in walking mode.
In this example the distance d corresponds to the value of the SWITCH DISTANCE field. If we take d to equal 25 metres, this identifies a disc with a surface of
1962.5 m ² ( π *25 ² ) centred on the point to be reached. As soon you enter the yellow zone, the Keymaze will assume that you have reached this point, and it will
then switch to guiding you to the next point. You are guided from one point to another by GPS (if you are moving) or in compass mode (if you've stopped). In this
case the compass gives you a direction taking into account the last known GPS position.
