16. CALIBRATION
This feature calibrates the screen of the device
for precise reading of clicks. You need it only if
the touch screen responds imprecisely.
17. ABOUT THE DEVICE
About the device page is the information
screen: it shows the serial number, version of
the software and the available memory.
18. GPS SIGNAL
Remember: This is only the information screen.
You can see the number of visible satellites
and the strength of their signal.
This screen shows your current position in
degrees of latitude longitude, and altitude.
The compass shows the image of satellites
whose signal is received by the device, and the
bar graph next to it, the strength of their signal.
REMEMBER:
In order to read your position correctly, the
signal of at least three satellites is required.
The functionality of the receiver may be
limited or inactive in your house and in the
majority of buildings when GPS signal is too
weak. It is a normal phenomenon in this type of
products.
