4.1.1 Menu Navigation
The behavior of the buttons is the same for both the Basic and Advanced Displays. The user must
press

button to call up the Main Menu. To exit the Main Menu and return to the PV display
screen, select <EXIT> .
When on a lower level menu, return to the menu above by selecting <Return>. Alternately, the (up
symbol) and (down symbol) buttons can be pressed simultaneously to return to the menu above.
When on the highest level menu, or when using the basic display menu, pressing the (up symbol) and
(down symbol) buttons simultaneously will exit the menu and return to the PV display. Use the

and

buttons to scroll through the list of menu items. Press the

button to select an item for data entry
or activation. When an item is selected for data entry or activation, the cursor will jump to the lower
line of the LCD (Basic Display) or call up a pop-up window (Advanced Display) to allow editing of
the value. No action is taken against a menu item until the

button is pressed.
If a user presses the

button to begin a data entry operation, they must press another button within
10 seconds or the transmitter firmware will assume that the user wants to abort the operation or has
walked away from the transmitter. After 10 seconds with no action, the data entry will time out and
the original value of the parameter will be preserved.
If no button presses occur within 60 seconds, menu access will time out and the transmitter will exit
the menu and return to the PV display.
4.1.2 Data Entry
Data entry is performed from left to right. Select a character / digit by pressing

or

buttons, and
then press

to advance to the next character position to the right. Select the cross-hatch character
▒
to terminate the entry or if the final character is already a space character, just press

again.
