The Touch Screen Calibration menu.
Press each of the targets in turn. After the third the screen should be
calibrated. The calibration screen will disappear, returning you to the
Interface Options menu. You may want to use a stylus for more accu-
rate calibration or even the plunger of a ballpoint pen – if you do, take
extra care not to scratch the touch screen.
Standby Mode vs. Power Off Mode
The power button turns the unit off and on in two different ways. When
the unit is on, holding the power button down for about two seconds
will put the unit in "standby mode." Standby Mode is your unit's de-
fault setting. It does not turn the unit completely off.
Standby Mode allows it to "sleep" and draw very little battery power.
Because the unit is not completely shut off the next time you turn it on
it will start up faster than if the unit was fully shut down.
If the unit is left idle for 24 hours it will automatically leave the
Standby "sleep" state and switch to a full shut down to save battery
power. However, the power button's Standby setting is unchanged; the
next time you power down it will again return to Standby Mode.
If you wish you can disable Standby Mode so that the unit will com-
pletely shut down when you turn it off. To disable it select

Units of Measure
This menu adjusts the units of measure the unit uses to display speed
and distance (statute miles or meters), your heading (true or magnetic),
the current time (12 hour or 24 hour format) and the date
(Month/Day/Year, Day/Month/Year or Year/Month/Day).
