Notes: GPS needs to be allowed by software. Some GPS functions must be preset by
software before use. For some GPS functions the radio location must be
identified successfully before use. Some GPS functions require other users to
have GPS functionality and their location been successfully identified as well
before use. The GPS Distance calculation or the use of some functions is for
reference only, which may cause errors due to some unexpected or
environmental reasons.
Notes: Because reception of GPS also requires some power from the battery it should
be turned off whenever not required.
