Entering Standby
You can put the 475 Field Communicator into standby to save power or to reduce the
boot-up time if you are using the 475 Field Communicator intermittently. Standby turns
off the touch screen and areas within the 475 Field Communicator.
You can put the 475 Field Communicator in standby when the HART Application or the
Fieldbus Application is running. If you are working online with a device when standby
is entered, the application main menu is displayed when the 475 Field Communicator
returns from standby. Otherwise, the 475 Field Communicator displays the last open
window.
To enter standby, press the Power 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 green light on the Power key slowly flashes when the 475 Field
Communicator is in standby. To leave standby, press the Power key.
The 475 Field Communicator also enters standby if the standby timer has expired. See
“Power Status” on page 2-14 for more information.
Shutting Down
To shut down the 475 Field Communicator, press the Power 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.
The 475 Field Communicator shuts down if the auto-off timer has expired. See “Power
Status” on page 2-14 for more information.
You can also shut down the 475 Field Communicator by simultaneously pressing the
Backlight 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 475 Field Communicator.
