at a time. Pressing the Shift and (+/-) keys once performs the same action,

keys performs the same action, unless a parameter setting is currently

Legend
Left Right Off:
Press this submenu key to turn off or to display a legend at
the top left or top right corner of the AZM map. The legend consists of a
vertical zoom level bar, a square representing the current GPS location and
base map, and three status icons (see
Figure 6-12 ). The zoom level
indicator shows the number of levels of zoom in the AZM map, with the
current level displayed as a dark segment on the vertical bar. Higher levels
of zoom are toward the top of the indicator bar.
The default square with crosshairs represents a map panel with the lowest
zoom. The crosshairs are at the center of that panel. As the zoom level
increases, a boundary of a panel is displayed around the crosshairs. The
higher the zoom level, the smaller the square around the crosshairs. When
panning the map (using the instrument’s arrow keys), the crosshairs and
map panel boundary display your relative location in the total mapped area.
When the lock is ‘locked’ (by pressing Enter ), the map is in auto-centering
mode and will update continually to keep your current position centered
while you move with the instrument. If you pan (using the arrow keys), the
map is taken out of auto-centering mode, or unlocked, because you have
intentionally shifted the map area away from your current location. When
unlocked, the map will not follow if you walk or drive around with the
instrument.
After panning, press the Enter key to re-center your GPS location on the
map and lock auto-centering mode.
