Battery Replacement

Your one way Remote Transmitter uses one battery type CR2032 for G777,G27,A777,A20,A15
which will require replacement in time. Depending on the amount of use, the battery may last up
to 48 months or more before it needs replacement.
When the battery needs replacing, the system's operating range will decrease or the transmitter
LED may be off or not be as bright.
In order to change the battery, first remove 2 screws from the back of the transmitter and
separate the top and bottom halves of the case.
While replacing the battery make sure that the positive and negative terminals are positioned
correctly, then carefully reassemble the transmitter case.
