81T Series Electronic Flush Valve with H2Optics®

Delta’s external battery strength indicator helps eliminate the needless changing of batteries. Hold the low profile override button for 5 seconds and a blue light appears indicating the troubleshoot has been recognized. Hold for an additional 5 more seconds and red lights appear indicating the battery strength (5 lights = full, 1 light = low). If a red light is flashing every 10 seconds then batteries are low and there is roughly 5,000 flushes remaining before the lifespan of batteries have ended. If one light is flashing then it is time to replace the battery.
