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.
BATTERY WARNING: Chemical Burn Hazard . Keep
batteries away from children .
