Shutting Down
the 375 Field
Communicator
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 battery
life or to reduce the boot-up time if you will be 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 HART or
fieldbus device when stand by is entered, the application
main menu will be displayed when the 375 Field
Communicator returns from stand by. Otherwise, the 375
Field Communicator will display the screen that was
open when stand by was entered.
To enter stand by, press the on/off/stand by 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/stand by key.
The 375 Field Communicator will also enter stand by if
the stand by timer has expired. See "Power Status" on
page 2-14 for more information.
To shut down the 375 Field Communicator, press the
on/off/stand by 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. This is a
mechanism by which 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 will also shut down if the
auto-off timer has expired. See "Power Status" on
page 2-14 for more information.
