Turning on for the First Time
To turn on your GM-120 Handheld GPS Navigator, press and hold the
Power button for two seconds. The product information page is displayed.
Next, the Mode Selection menu appears. Use the navigation keys to
select the mode you want and press the OK button to confirm.
Press the Menu button twice and select Satellite. The GM-120 starts
acquiring satellite information as described in the following section.
Acquiring Satellite Information
The satellite page displays information obtained from
the GPS satellites. The upper half of the screen
displays the satellites found in the vicinity and their
respective numbers.
The vertical bars on the bottom of the screen show the
signal strengths acquired from the satellites. The GPS
requires at least 4 satellites to determine its position.
Once the GPS position has been correctly determined,
the position coordinates are displayed at the bottom of
the screen.
NOTE:
In order to operate each mode at its optimal performance,
the GM-120 must have its position determined by the
satellites.
