3. Operational Description
3.1. Backlight in Active and Sleeping Mode .......................
The rfCUE 99 panel is equipped with two colors (red / green) back-light / indication LEDs that light on
whenever the rfCUE 99 is in active mode. When in sleeping mode all the back-light / indication LEDs
go dark. The sleeping mode is terminated after pressing the back-light button or any other button on
the rfCUE, the backlight LED will light on for the time of about 6 - 8 seconds the rfCUE 99 remains
active. Then the rfCUE 99 goes to sleeping mode to reduce power consumption. In sleeping mode the
rfCUE 99 does not transmit or receive any RF signals.
3.2. Transmit / Receive Indication....................................
When the rfCUE 99 is transmitting or receiving valid RF data packets it flashes shortly
(approx. 0.2 second) the red LED under backlight pushbutton. The flashing of this LED becomes
visibly longer when the rfCUE 99 gets out of its RF operating range.
3.3. Operation of the Feedback Indication ........................
The rfCUE 99 is equipped with two colors (red / green) indication / back-light. The color of each button
LED can be controlled from the program of the control system.
There exist several very important differences when using this type of indication on the wired and the
wireless panel
• The rfCUE 99 is not active all the time it goes to sleeping mode. The rfCUE 99 does not
transmit or receive any RF signals in the sleeping mode and all its LEDs remain dark and so:
It is not able to make any indication. All commands operating with button LEDs during that
time are stored in rfbaseCUE until the rfCUE 99 becomes active. Then the latest status of the
button LEDs is re-transmitted. During the time when the rfCUE 99 is not active the rfbaseCUE
makes periodical attempts to establish new communication.
• It is very important to have in mind that similar principles of operation is valid also for the case
when the rfCUE 99 gets out of its RF operational range even if it is in active mode!
• If the rfCUE 99 gets out of its RF operational range the displayed indication remains according
to the status of last valid communication. The last status also remains when it wakes up from
sleeping mode.
• The rfbaseCUE can operate with more than one rfCUE 99 in one system.
• When the rfbaseCUE is after reset it does not send any information to any rfCUE 99 until the
valid communication with some rfCUE 99 is established. It means: There is no indication on
the rfCUE 99 before first button on the rfCUE 99 is pressed.
