RFA Operational Range

Operational range varies with the orientation of the transmitter. For best performance, hold the transmitter vertically, with the buttons facing you and the bottom cover of the transmitter towards the vehicle. As battery life decreases, so does the maximum operational range of the RFA transmitter. In most cases, the transmitter battery should only be replaced when the operational range has severely decreased. If the transmitter range decreases or the transmitter does not operate, test for the following conditions:
^ Test if battery replacement is necessary
^ Test for proper range (Rainy or snowy weather decreases range)
^ Test for obstructions (other vehicles or objects will decrease range)
^ Electrical interference (cellular phones, power lines, radio towers, garage door openers, etc.)
^ The transmitter is not programmed or synchronized to the vehicle
