1/ Programming the desired hand transmitter button
Push the P button on the Ecostar operator motor cover briefly. The red LED will begin to 
flash, signalising that the desired hand transmitter button can be programmed. 
To do so, the hand transmitter button must be held down until the LED begins 
flashing rapidly. The hand transmitter button must then be released and pushed 
again within 15 seconds, until the LED begins flashing very rapidly. Now, 
release the hand transmitter button. Once the rapid flashing stops, the desired 
hand transmitter button has been successfully programmed and the red LED will 
remain lit.
2/ Deleting the remote control memory in the radio receiver  
(recommended if a handset has been lost or stolen)
Push the 'T' button on the operator cover and hold it down. The 
red LED will flash slowly for approx. 4 seconds, signalising readiness for 
deletion. The flashing rhythm becomes more rapid. Now, release the P button.
Note: The deletion process will be aborted if the P button is released before 4 
seconds have elapsed. Once the rapid flashing stops, all memory spaces have been 
deleted and the red LED will remain lit. Follow the programming procedure to 
re-programme your keyfobs
