3. Basic use
The GPS module should only be used outdoors to allow reception of GPS signals.
GPS should not be used for precise location measurement, and you should never
rely solely on location data from the GPS module. Virtually all digital cartography
is always inaccurate and incomplete to some extent. Never rely solely on the
cartography provided for use with this device.
The use of this GPS module requires your mobile phone to be switched on. Do not
switch on your mobile phone where it may cause interference or danger.
