Using the Main Power Switch
When the GPS unit is shipped from the factory or when the unit is stored for long period of time,
the main power switch should be in the “off” position.
When the position is changed to “on” the touch screen calibration screen is displayed. Follow the
instructions on the screen until completed.
Charging the Battery - In Home
Before using the GPS for the first time, we strongly suggest you fully charge the battery. Before
the unit can be charged it must first be manually turned on. See Figure 12A. This switch connects
the battery.
Assemble the AC adapter:
The AC adapter needs to be assembled prior to
use. Follow the diagram in figure 12C to insert
the plug section to the main adapter body.
