FLASH MESSAGE TIME

Default: 5 s
Flash messages are status, warning, error, or information messages displayed for
several seconds in response to certain key presses during programming. These
messages override any normal messages. The duration of a flash message on the
display can be changed to accommodate different reading rates.
MESSAGE TIMEOUT
Range: 10 to 900 s in steps of 1 s
Default: 30 s
If no pushbutton has been pressed for certain period of time, the relay automatically
reverts to its default message (screen). The inactivity time is modified via this setting to
ensure messages remain on the screen long enough during programming.

When the screen saver is set to ON, the LCD backlighting is turned off after the Message
Timeout followed by a time of 5 min, providing that no PB has been pressed and no

LCD backlighting is turned on.
