When using the unit for the first time
When you use the unit for the first time, a search for all GPS satellites will
be performed in order for the unit to recognize available GPS satellites and
positioning takes time for the first time.
When the unit cannot receive satellite signals
If you are in the tunnel or basement and therefore out of the reception area
for GPS satellites, or near high buildings, trees or other obstructions, no
signal will be received, or the current location may be inaccurately
indicated.
Typical areas of poor/no reception:
• tunnel
• Indoors or behind buildings
• between high buildings
• narrow road between buildings
• basement
• dense trees
• under elevating structures
• near electromagnetic sources, such as high-voltage electrical power lines
• near 1.5 GHz mobile phones or similar frequency devices
• between heat-reflecting glass
Notes
• The unit may take time to positioning or cannot measure the positioning
depending on the place where you use or depending on the time when
you use because the location of the GPS satellites is moving constantly.
Even if enough number (3 or more) of the satellites for positioning are
activated, positioning may take time longer than usual depending on the
position of the satellites.
If you cannot do positioning properly, try changing the place where you
are using the unit to the broad area.
• Obstructs from GPS satellites may not only buildings or trees, but also a
part of your body. If you cannot do positioning properly, keep the
antenna face of the unit as far away (more than 30 cm) from your body.
