If you want the iFINDER to record your altitude as well, you must cali-
brate the altimeter by providing the known altitude at a current loca-
tion. To do this, from the Digital Data display, press
MENU then choose
CALIBRATE ALTITUDE. You can accept the altitude value provided by your
GPS position, or manually enter the altitude of your current location.
Then select
SAVE CALIBRATION and press ENT. The iFINDER will now
track your altitude with its built-in altimeter.
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, position values, or to return to atmospheric pressure values.
Sleep Mode
We've designed the iFINDER with a Sleep Mode that allows it to con-
serve battery life, while occasionally waking up just enough to take
pressure readings for the altimeter and weather prediction. This allows
the unit to continue to build an accurate history even when you're not
actively using it.
There are a couple of ways to enable Sleep Mode. If you're viewing the
Digital Data page, 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
PAGES 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
PAGES 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
PAGES key the iFINDER will
return to
SLEEP MODE.
