Battery Compartment

To Remove

• Insert one CR2032 battery into the compartment

with the + side up.

• Slide back into place.

A weak or missing battery can cause the time, date,

and program to be erased after a power failure. If

this happens, you will need to install a fully charged

battery and reprogram the timer.

Tip: Replace battery every year, to avoid loss of

programming.

Note: A battery alone will not operate the valves in your

sprinkling system. The sprinkler timer transformer must

be connected to an AC line voltage source.
