If an error has occurred or an incorrect channel is
entered, the LED will flash quickly for a second and
return to the previous settings.
If two adjacent channels are selected, the unit will
accept the entry but will blink the LEDs of channels
that are too close. If this happens, re-program one
of the channels to move it away from the other.
