Radio Signals for Some Gate
Operators
Some gate operators and
radio-frequency laws require
transmitter signals to time out or quit
after several seconds of transmission.
This may not be long enough for the
Universal Remote system to pick up
the signal during programming.
If the programming did not work,
replace Step 2 under“Programming
the Universal Remote System ”with
the following:
Press and hold the Universal Remote
system button while pressing and
releasing the hand-held transmitter
button every two seconds until the signal has been successfully accepted
by the Universal Remote system. The
Universal Remote system indicator
light will flash slowly at first and then
change to a rapid flash or continuous
solid-light. Proceed with Step 3 under
“Programming the Universal Remote
System
”to complete.
