Operation

Note: The hitch height MUST be set in the memory prior to
the normal operation of the Smart Jack. Failure to do so
will cause the Smart Jack and the trailer to not function
as intended.
Note: The battery indicator light (Fig.5C) flashes or
oscillates to validate certain functions of the Smart
Jack. The light also displays the remaining battery
charge of the trailer.

Setting Hitch Height Memory

1. Press and hold the up arrow (Fig.5A) and down arrow
(Fig.5B) at the same time for a minimum of 5 seconds to
store the vertical position of the Smart Jack.
2. The battery indicator lights (Fig.5C) will flash 5 times
to show that the new position is successfully stored in
memory.

Normal Operation

3. Press and hold the up arrow (Fig.5A) to extend the
Smart Jack.
4. Press and hold the down arrow (Fig.5B) to retract the
Smart Jack.

Return to Hitch Height Operation

5. Press and release the up arrow (Fig.5A) and the down
arrow (Fig.5B) at the same time 3 times, holding on the
3rd time for several seconds until the jack engages and
the indicator light oscillates back and forth.
6. The jack will automatically retract or extend to the
original hitch height position.
Note: Visual indication that the jack is actuating to the
hitch height is seen through the oscillation of the battery
indicator lights (Fig.5C) e.g. lights will illuminate left to
right, and then right to left. This will continue until the
original hitch height is achieved.
Note: To cancel an action, press either the up arrow or
down arrow. The action in process will stop.
