All you need to do is push one (1) pin outward for each time
you want to feed per day with the right side of each
pin pushed outward facing the time on the clock you want to feed.
Then all you do is rotate and set the clock dial with the correct
present time facing the black arrow just above the timer switch. If
it ever loses time, like a power outage, simply rotate the dial a
few clicks clockwise to reset the time to correct time facing the
black arrow at the right side of the dial.
The red little lever on the timer switch MUST BE pushed
in the down position for
automatic "on-off" mode (no red light on). In the upper position (I), it is in
override (continuously ON), meaning that you can "manually" turn
on your feeder by going to that position until the feed cycle is
complete for extra manually initiated feed cycles (feeder must
have been off for at least two minutes prior to doing that), then you
return it to automatic mode (TIMER position) by pushing the red
lever back down. When the timer is on, you will see a red light
on the timer. The timer will only be on for 15 minutes for each
tab pushed outward on the outside of the dial The feeder
will spend most of its life in the off mode. Basically,
you operate the timer as if you were turning a lamp on at
programmed times.
You also have instructions on the back of the blue card inside the
timer blister pack.
If you ever suspect something wrong with the timer, just make sure
the dial turns as time changes. If it does not, there could be
something wrong with the timer. You may even be able to hear a
light buzzing sound while plugged in to confirm it is running.
