Entering
Stand-By
The 375 Field Communicator can be put into stand-by,
which turns off the display and certain areas within the
375 Field Communicator. Use this option to save power
or to reduce the boot-up time if you are using the 375
Field Communicator intermittently.
You can put the 375 Field Communicator in stand-by
when the HART Application or the Fieldbus Application
is running. If you are working online with a device when
stand-by is entered, the application main menu is
displayed when the 375 Field Communicator returns
from stand-by. Otherwise, the 375 Field Communicator
displays the last open screen.
To enter stand-by, press the On/Off key. From the Power
Switch dialog box, tap
Stand by and tap OK or press the
Enter key. Tap Cancel to close the dialog box and return
to the application. The multifunction LED will slowly flash
a green light when the 375 Field Communicator is in
stand-by. To leave stand-by, press the On/Off key.
The 375 Field Communicator also enters stand-by if the
stand-by timer has expired. See “Power Status” on
page 2-18 for more information.
Shutting Down
the 375 Field
Communicator
To shut down the 375 Field Communicator, press the
On/Off key. From the Power Switch dialog box, tap
Shut
down and tap OK or press the Enter key. Tap Cancel to
close the dialog box and return to the application.
You can also shut down the 375 Field Communicator by
simultaneously pressing the Backlight Adjustment key
and the Function key until the display turns off. The shut
down is accomplished in the hardware (similar to
removing the power to a PC using a switch). This is not
the recommended way of shutting off the 375 Field
Communicator.
The 375 Field Communicator shuts down if the auto-off
timer has expired. See “Power Status” on page 2-18 for
more information.
