LEDs
When the Handheld is fully charged, the green Power LED glows steadily Green. When the unit
is unplugged from AC or the Battery is not charging the LED is off. While the battery is
charging the LED is Amber. If there is a low battery the LED will flash Red. If there is a fault
or no battery present the LED will be solid Red.
Turn On the Handheld
If your Handheld has been turned off turn it on by pressing the Power button, located on the
upper right-left side of the Handheld’s frame. The first time you power on your Handheld, it
will take about 45second.
Instant On/Off
After the initial power on, the Handheld instantly turns on when you press the Power button, and
instantly turns off when you press the Power button again. The Grayhill Handheld provides
these Instant On and Instant Off features to facilitate your work under harsh conditions.
Align the Handheld Touch Screen
The Handheld’s touch screen may initially require calibration to align the cursor on the touch
screen with the tip of your stylus. To calibrate your screen tap the center of each alignment
target with the tip of the stylus.
Resetting
By default, the Handheld’s Instant Off feature causes it to immediately power down to a “sleep”
mode where closed programs are still running, but the screen’s backlight is off. If no use is
planned for the Handheld for the near future and batteries need to be removed, you can
reconfigure the Instant Off feature to cause the Handheld to turn off completely instead of going
to sleep. You’ll use the
Power
control panel in
Settings
to reconfigure Instant Off (see page ).
Pressing Power on a Handheld with Instant Off configured to completely turn off the Handheld
causes a hard reset of the Handheld. When the Handheld is powered on again, all data saved to
flash memory will still be present.
Soft resets of the Handheld are accomplished by selecting
Restart
on the Handheld’s
Start
menu,
or by responding affirmatively to a request for a restart from an installer or other program.
To conduct a hard reset hold the power button down for 6-10 seconds. This will clear the
Handheld's ram and reload the OS from Flash.
