Here it is verbatim...The Ctl head waits approx. 5 sec. before sending the new code to the transponder. This provides time for verification of the selected code before it is transmitted and prevents inadvertant transmission of a partially set code. For 7700 & 7600, the display (Ctl Head) flashes the code for 5 sec. before sending the code to the transponder.--CY
