Preface
Precautions
For safety, we strongly recommend that you never operate the GPS navigation system
while driving.
Furthermore, attention should be paid to the following basic precautions when operating the
ProGin N-380:
● The SD card should be removed only after you press the power button to shut down the unit.
Never pull out the SD card while the N-380 is operating.
● Never press the power button repeatedly or continuously. Otherwise, the unit could be
damaged.
● Never expose the ProGin N-380 to strong sunlight or heat for extended periods of time. The
acceptable operating environment of the ProGin N-380 is 0~70°C and 0~90% humidity. The
acceptable storage environment is -10~80°C and 0~90% humidity.
Also, when operating the GPS functions of the ProGin N-380, these additional precautions apply:
● This system functions as a reference for navigation only, and should never be used for
accurate measurements of direction, distance, location, etc.
● For GPS satellite positioning to work, stay at the same location until the positioning process is
complete. It is best to stay in an open, uncovered location. This positioning process may need
more than 10 minutes.
● When the system is located in a building or a tunnel, or is close to a high obstacle, the system
may temporarily be unable to provide positioning and navigation information.
● Any radio transmitters (including mobile phones) might interfere with GPS satellite signals,
thereby resulting in incorrect positioning information.
● If your car is equipped with sheathing paper or explosion-proof plaster, these features might
interfere with the quality of the GPS signal.
