In order to"Reboot"your sprinkler timer you must unplug the timer from the 110 v outlet and remove the 9 v battery,let it set for a short time and then replace the battery and plug the timer back in.This process will clear the memory,you may then reprogram the timer according to the instructions printed on the cover.Hope this helps.(PS. the key is to disconnect the battery as its reason for being there is to retain the memory in a power outage)
