IMPORTANT When the controller’s Battery Low indicator is lit, check whether the battery
wire connector is connected correctly or replace the replaceable battery
with a new one immediately. When the indicator turns on, it means that
either the battery is disconnected, or that the battery requires
replacement. The controller is designed to operate for up to 2 weeks, from
the time that the indicator first turns on. We recommend that you replace
the battery immediately when the indicator turns on.
