Spectra 1641BL 11
BACKLIGHT FUNCTIONALITY
When the system is in Confidential Mode or during an AC
power loss, the intensity of the keypad’s backlight
automatically decreases to a Level 1 setting. During this time,
if a key is pressed on the keypad, the backlight switches to
regular intensity and then returns to the Level 1 setting when
all actions on the keypad cease. The backlight returns to
regular intensity when the system is no longer in Confidential
Mode or when AC power is restored.
