Operation
The numbered buttons 1-4 and 7-0 correspond to the jack locations while looking forward from the rear of
the camper. Arrows on the buttons indicate the direction of the camper movement. Red buttons raise the
camper and blue buttons lower the camper.
1. Press and hold button 6 (Fig. 1) (All Up) to raise the camper.
NOTE: Because the weight of the camper is not the same at all four corners, the jacks will not raise and
lower at the same speed. Take care not to get the camper more than four inches out of level. When
running all four jacks, stop often to check level and make sure all four jacks are on the ground.
2. Press buttons 1-4 and 7-0 to raise or lower jacks individually to help level camper.
3. Press and hold button 5 (All Down) to lower the camper and retract the jacks.
4. Once the jacks are retracted for travel, reverse the motors and extend the jacks slightly. This prevents
the jacks from locking up in the fully retracted position.
Safety Features
Overcurrent Shutdown
When any jack reaches the end of travel, either at full retraction or full extension, an overcurrent situation
will cause the remote to shut down operation of all jacks and sound an alarm.
1. At the time of the alarm, press each jack button individually in the direction of travel.
2. When the alarm sounds again, this is the jack which has amped out and cannot be moved farther in
that direction. Operation of the other jacks is not affected unless they reach the end of travel and amp
out as well.
Never leave jacks bound in either the fully extended or fully retracted position.
Never allow the back of the camper to become higher than the front. The camper will load best and
more safely if the front is kept two to four inches higher than the rear.
Always keep the motor release/locking lever on the side of the jack in the up (engaged) position
except when the hand crank is installed.
Never lift beyond the DANGER warning on the jack's inner leg. Jack damage could result,
compromising jack performance and creating a safety hazard with repeated overextension.
Never leave the jack fully retracted. Once the jacks are retracted for travel, reverse the motors and
extend the jack slightly. This prevents the jack from locking up in the fully retracted position.
3. A bind due to uneven loading of the jacks may also cause the motors to amp out. Reverse the jack,
correct the load issue and continue to load or unload.

Operational Time Out
Any button held down for one continuous minute will cause a time out and all operation will cease. The
button must be released and then it or another button pressed to continue the operation. The purpose of
this feature is to minimize the risk of getting the camper dangerously out of level.
Idle Time Out
If no buttons have been depressed for two minutes, the system will shut down and the indicator light will
go out. Both the remote and the receiver will shut down. The purpose of this feature is to automatically
shut down the system when not in use. This reduces the possibility of tampering or accidental activation by
children or others.
1. Reset the remote by simultaneously pressing the All Up and All Down buttons (Fig. 1).
2. Reset the receiver by simultaneously pressing the ACC. IN and ACC. OUT buttons (Fig. 1).
Manual Jack Operation
In the event it becomes necessary to operate one or more of the jacks manually due to a malfunction of the
system or a dead or low camper battery, utilize this procedure.
1. Remove the protective weather cap and insert the hand crank handle into the crank socket on the jack.
2. Flip the motor release/locking lever on the side of the jack to the down position. This will disengage
the motor head from the jack, allowing it to turn freely by hand.
3. Manually raise or lower jack to the desired position.
4. Return the locking lever to the up position when not hand cranking. This engages the motor and
provides a secure lock for the jack.
5. Remove the crank handle.
Troubleshooting Table
Just as when using the remote feature, take care to keep the camper relatively level and do not
allow the front of the camper to become lower than the rear.
What Is Happening? Why? What Should Be Done?
Remote will not turn
on. No green light.
Dead or weak battery in
remote unit.
Remove six screws from back of remote and
replace AA battery.
Plug in coiled phone cord between remote and
receiver until battery can be replaced.
Defective remote. Replace remote.
Green light on
remote but jacks will
not operate.
Receiver needs reset. Simultaneously press ACC. IN and ACC. OUT.
Insufficient power to
operate jacks. (Red light on
receiver panel.)
Charge camper battery or plug into AC power, if
available.
One or more jacks
will not operate.
Blown fuse(s) on receiver
board.
Replace blown fuse(s). If fuses continue to blow,
contact LCI.

Tips on Loading, Unloading Truck Camper
• Never allow the front of the camper to become lower than the back of the camper.
• Never back into or turn into the jacks.
• Never leave the camper in an elevated position supported by jacks alone. Lower camper to the ground or
support the weight on fixed platforms, such as saw horses.
• Keep the camper level side-to-side.
• Make sure the camper is clear of the truck bed when backing and pulling out.
• Stop frequently when loading and unloading to ensure camper is level side-to-side and the front is slightly
higher than the rear.
• Keep the load on the four jacks as evenly distributed as possible. No one jack, especially when swingouts are
used, will support the shifting weight of the camper if a disproportionate load is shifted onto it.
Maintenance
Jacks
When the jacks have been unused for an extended period, owners are encouraged to oil the jacks to
improve performance.
1. If jacks are fully retracted, place motor release lever in the down position.
2. Use the hand crank to extend the jack a few turns before engaging the motors.
3. Place a few drops of oil or spray a light penetrating oil at the interface of the crank socket and hub or in
the oil hole within the hub. The oil will wick into the bushing and improve performance.
4. Reset motor release lever to the up position.
Remote
Keep remote dry and away from moisture. Do not leave remote outdoors or in outside compartments when
not in use. Store the remote inside the truck or camper.
