Fig. 60. Language setup
The up and down arrow buttons are used to scroll between the possible selections and
highlight the one the user wants. The left arrow button is used to exit this page and not
make any language change (page is exited and control returns back to Display setup
menu). The right arrow or OK button is pressed to set the language to the highlighted line. A
final confirmation is asked (see Fig. 61) before committing to the new language setting.
Fig. 61. Language change confirmation
The right and left arrow buttons are used on the confirmation line to tab between "Yes"
and "No" options. Pressing the OK button executes the highlighted option. When "Yes" is
executed the display module switches to the new language. When "No" is executed the
language change is canceled and the language remains as it is. In both cases control
returns back to the Language setup menu.
Heater Mode
Display has a heater function used to improve legibility and refresh rates in low
temperature situations. The display heater feature is available for all models except for
those listed on page 43 Models that do not use the Heater Function.
Heater panel operation can be set by the user to one of the following settings:
• Automatic (default) – heater turns on when internal temperature reaches 50 °F (10 °C) or
below
• On – heater is on always
• Off – heater is off always
Heater mode setup is accessed from the Display setup menu (see Fig. 62). The current
setting is displayed when the page is initially entered.

The up and down arrow buttons are used to scroll through the mode settings on the edit
line. The right and left arrow buttons are used to tab to the save commands, "Yes" and
"No". When the input focus is on the save commands the up and down arrow buttons scroll
between "Yes" and "No". When the mode is set to the desired value the "Yes" command is
selected and the OK button is pressed to commit the change. If the user decides not to save
the displayed mode, the "No" command is selected and the OK button is pressed. In both
save command cases control returns back to the Display setup menu.
Display Password
The display module password can be edited to a new 3-digit setting. Password setup is
accessed from the Display setup menu (see Fig. 63).
