You can use the arrow keys to move back and forth through the avail-
able pressure history. Use to move back in time, selecting previous
readings, or to move forward in time. The exact value of the selected
reading is displayed on screen. You can also use to switch to altitude
values, or to return to atmospheric pressure values.
Sleep Mode
Of course, when the iFINDER has more information to work with, it
can provide better predictions. In order to help with this, we've de-
signed the iFINDER with a Sleep Mode that allows it to conserve bat-
tery life, while occasionally waking up just enough to take a pressure
reading. This allows the unit to continue to build an accurate pressure
history even when you're not actively using it.
There are two ways to enable Sleep Mode. If you're viewing the Digital
Data display, simply press
MENU and select ENABLE SLEEP MODE, then
press
ENT.
If you're viewing one of the other displays, press
MENU|MENU| to
SYSTEM SETUP|ENT| to ENABLE SLEEP MODE|ENT.
A dialog will ask you to confirm your choice. Choose
YES, and the
iFINDER will appear to turn off.
NOTE:
Sleep mode can be activated from any page by holding down the
MAP/MUSIC key for 5 seconds.
When the iFINDER is in Sleep Mode, you can return to normal operation
by pressing
PWR. You can also use the Instant-On Compass feature to
briefly display the compass reading, without reactivating the entire unit.
Instant-On Compass
When the iFINDER is in Sleep Mode, you can still quickly check your
compass bearing by pressing and holding the
MAP key. This activates
the screen and shows the current Compass display, including your cur-
rent heading and any information you are displaying in the customiza-
ble data boxes. As soon as you release the
MAP key the iFINDER will
return to
SLEEP MODE.
Compass Display
This display has a compass rose. It shows your facing direction and the
direction to a selected destination. The navigation screen looks like the
one in the following image when you're not navigating to a waypoint or
other destination. No graphic course information is displayed. Your
facing direction is shown by an arrow on the edge of the compass rose.
