Communicator.
Action Keys
As shown in Figure B-4, the action keys are the six blue, white, and
black keys located above the alphanumeric keys. The function of each
key is described as follows:
ON/OFF Key
Use this key to power the communicator. When the communicator is
turned on, it searches for a transmitter on the 4–20 mA loop. If a device
is not found, the communicator displays the message, “No Device
Found. Press OK.”
If a HART-compatible device is found, the communicator displays the
Online Menu with device ID and tag.
Directional Keys
Use these keys to move the cursor up, down, left, or right. The right
arrow key also selects menu options, and the left arrow key returns to
the previous menu.
Hot Key
Use this key to quickly access important, user-selectable options when
connected to a HART-compatible device. Pressing the Hot key turns the
communicator on and displays the Hot Key Menu. See “Customizing
the Hot Key Menu” in the Model 275 HART Communicator Product
Manual (Rosemount publication no. 00809-0100-4275) for more
information.
