Battery Replacement
Your Ungo Remote Transmitter uses a 12 volt alkaline battery, which will need to be replaced
from time to time. Under normal conditions, the battery should last for up to a year before it
needs replacement.
When your Remote Transmitter’s battery is in need of replacement, you will notice a decrease in
your system’s operating range or a decrease in the brightness of the Transmitter’s LED indicator.
To change the battery, remove the 2 screws at the back of the Transmitter and carefully separate
the top and bottom halves of the Transmitter case.
Insert the new battery, making sure that the positive and negative terminals are positioned
correctly and replace the cover.
Battery Type: 23A
