Battery Installation
The Lawn Master II maintains the programmed schedule and its
time and date by using a 9V battery backup. In the event of a
power outage and the 9V battery is not installed or very low in
power, the controller will reset the date and time to the default
01-01-2007 and 12:00am. Any scheduled watering that is
programmed in the Lawn Master II will also be lost.
Replace the 9V battery yearly to assure that the current
time, date and scheduled programs are retained.
IMPORTANT! Check the controller’s scheduled watering
program after every power outage to prevent interruption to your irrigation
system’s activity.
Step 1 – Remove the controller’s lower panel cover to access the battery compartment.
Step 2 – Install the 9V battery to the battery plug.
Step 3 – Secure the battery into the compartment.
Step 4 – Reinstall the lower panel cover.
