course and, after some seconds, a new display appears. Some Warning
messages can appear : please refer to the Error and Warning Message
Section. Press any key if requested.
The transmitter's type, Pressure or Temperature and the TAG are
displayed. If the Tag is not yet defined the space after the semicolon will

WORD
To access a transmitter you can use the TAG name.
If a tag has already been written in the transmitter two methods of access
can be used depending if the Tag is included in the Communicator
Database or not included. In the first case, pressing F2 (TAG SEL) in the
Access Method Menu, the tags stored in the Communicator are displayed,
four per display, at a rate of 3 seconds: using F1 you can stop the listing
whereas with F2 or F3 you can move forward or backward in the list. When
the required tag is on the display, you can select it moving, using F4, the
cursor on it: now pressing the ENTER key you make the selection.
The second method of access is via TAG ENTER; in this case the
following display appears. Use the key board to input character and the
key F1 and F2 to move the cursor. The key F3 can be used to clear the
tag name on the screen.
When, using one of the methods, the tagname has been composed press
ENTER to establish the communication with the selected transmitter.
In the top right angle of the display will appear a symbol, like a T, signalling
that the communication is on course and, after some seconds, the display
at side appears. If Warning Messages are displayed, please refer to Error
and Warning Message Section for details. Press any key if requested.
