If the light level is greater than or equal to -12.0dBm and less than or equal to +3.0dBm, the display will show the actual input

When the display select button is pushed three (3) times, the display will become that shown below. This is also the temporary

2.2.1 Control Button Operation
When no button has been pushed for 20 seconds or more, the display will revert to idle mode. In idle mode, the UP and
DOWN buttons are ignored. In order to change the setup of the OTPN-MDN-870 Mini Digital Node, push the SELECT button.
This will cause the unit to enter the equalization update mode. The EQ: text on the display will flash. Hitting the SELECT
button again will cause the unit to enter the attenuation update mode. The ATN: text on the display will flash. Hitting the
SELECT button additional times will cause the unit to toggle between the equalization update mode and the attenuation up-
date mode. Again, if no button is pressed for 20 seconds or more, the unit will revert to the idle display mode.
