Find Your Current Position

Finding your current position is as simple as turning the unit on. Un- der clear sky conditions, the unit automatically searches for satellites and calculates its position in approximately one minute or less.

NOTE:

"Clear sky" means open sky, unobstructed by terrain, dense foliage or structures. Clouds do not restrict GPS signal reception.

If for some reason satellite acquisition takes longer, you may be inside a structure or vehicle or in terrain that is blocking signal reception. To correct this, be sure you are positioned so that the unit's antenna mod- ule has as clear a view of the sky as possible, then turn the unit off and back on again.

Moving Around the Map: Zoom & Cursor Arrow Keys

The map is presented from a bird's eye view perspective. The current zoom range shows in the lower left corner of the screen.

1.Press the ZIN key (zoom in) to move in closer and see greater detail in a smaller geographic area.

2.Press the ZOUT key (zoom out) to move farther away and see less map detail, but a larger geographic area.

When you are traveling, the map will automatically move as you move. This keeps your current location roughly centered on the screen.

You can manually pan or scroll the map northward, southward, east- ward or westward by using the arrow keys, which launch the cross-hair map cursor. This allows you to look at map places other than your cur- rent position. To clear the cursor, press EXIT, which jumps the map back to the current position or the last known position.

Tip:

Use the cursor to determine the distance from your current position (or last known position, when working indoors) to any map object or location. Use the arrow keys to position the cursor over the object or place. The distance, measured in a straight line, appears in the popup data box. Press EXIT to clear the cursor.
