Press the Save Tab pushbutton, which does a range check on the value, saves the setting when valid, closes the page, and
displays the previous page.
When a setting is not saved due to an invalid value, a message flashes, for example being out of range. In cases where the
relay needs to be restarted for settings to take effect, the flash message advises.
Setting entry can be cancelled without impact on the original value by pressing the
ESCAPE or Home pushbutton.
Alphanumeric text
Settings that accept alphanumeric values display a keyboard. An example is a pushbutton name.

for example between English and French. (The second language needs to be activated under
