capability and one without; they are not interchangeable.

m warning

Personal injury & Product damage

• To deactivate the wireless system when you are finished hold down

the power-select on the remote until the LED turns off.

• Only operate jack system when camper or trailer is unoccupied.

• Store remote in a secure place, away from access by children.

• Remove the battery from the handheld remote before storing to

prevent accidental jack activation or continuous remote transmission.
If the remote is continuously activated by a jammed or shorted button,
operation of other remote devices such as vehicle keyless entry systems
and/or garage door openers may be interfered with or prevented.

• To avoid possible interference with blasting operations, do not use

your remote near e l e c t r i c a l b l a s t i n g c a p s or in a b l a s t i n g a r e a or in areas
posted: tu r n o f f t w o -w a y r a d i o . Obey all signs and instructions.

• Do not use the remote near explosive atmospheres.

Explosive atmospheres are often, but not always, clearly marked. They
include fueling areas, fuel or chemical transfer or storage facilities:
areas where the air contains chemicals or particles, such as grain,

m caution

Product damage

• Disconnect power to the power relay module prior to HiPot testing

of the camper or the microprocessor will be damaged.

n o t e : f i g 4 is overhead view of a pickup camper with power relay

module shown flat for clarity. f i g 5 is overhead view of 5th wheel trailer.

1. Install the power relay module in a clean, dry interior area protected
from moisture. Use the four (4) 1/4˝ diameter holes for mounting the
module relay (K). Position the base on the mounting surface and
secure it using appropriate hardware for the wall material. Orient
antennae straight away from base. Permanently secure antenna to
mounting surface with appropriate hardware. Mount the base RF
receiver unit (K) in the selected target location. Take care to ensure
that the antenna on the board is not located next to other electrical
wiring which could interfere with operation. Take care to ensure that
the target location has good RF reception (avoid “faraday cage”
scenarios, i.e. metal box).

m caution

Product damage

• Failure to orient antennae properly will result in intermittent

operation of the wireless remote system.

n o t e : Correct polarity must be observed as noted on the circuit board

next to 5 & 4-H. The unit will not function if the input power is installed

in reverse polarity. See f i g 5 & 4.

2. s u p p l y p o w e r t o u n i t : The unit operates from a +12 VDC battery and must
be supplied through a 40 AMP circuit breaker (f i g 4E & 5-E). Route the
#8 AWG, +12 VDC from the circuit breaker and the ground wiring, to the
terminal block (f i g 4H & 5-H).Terminate the wires in the labeled positions.

3. Route the two #10 AWG wires from each jack to the terminal block 4-I
& 5-I. Refer to the labels next to each terminal position for driver front,
passenger front, driver rear, and passenger rear jacks. Connect the
wires for each jack.

4. Install the Activation Switch near the floor just inside the door of the

pickup camper or in an outside compartment of the fifth wheel. Plug the
flat cable (f i g J) into the left side of the power relay module (f i g 4 & 5-S)
and route to the location of the activation switch (f i g 4 & 5-Q). Plug other
end of the cable into the back side of the activation switch. Connect the
optional accessory harnesses (controlling up to two additional motor
outputs) to their associated connector on the base receiver. Any use of
the accessory ports needs to be approved in advance by the manufacture
of the accessory. Connect the power harness to the base receiver. Take

m warning

Personal injury & Product damage

• Do not replace or charge batteries in a potentially explosive

atmosphere. Contact sparking may occur while installing or removing
batteries and cause an explosion.

• All batteries can cause property damage and/or bodily injury such

as burns if a conductive material such as jewelry, keys or beaded
chains touches exposed terminals. The material may complete an
electrical circuit (short circuit) and become quite hot. Exercise care
in handling any charged battery, particularly when placing it inside a
pocket, purse or other container with metal objects.

REMOTE BATTERY INSTALLATION:

1. Firmly slide battery cover (remote back) down to remove.
note: The audio cable can optionally be used to power the
transmitter directly from the switch assembly.

2. Insert one 9V battery.

3. Replace the battery cover and slide up until secure.
The battery type is 9V alkaline battery which will provide approximately
45 minutes of continuous use.

m warning

•

Sandy/soft/spongy ground may cause jacks to sink; camper may tip over.
Jack must be on firm solid ground prior to operation.

• Insure area below and around jack is clear of obstructions.

• Do not place blocks under the jack for additional ground clearance.

• Always keep the front of camper higher than or equal to the rear

of the camper. Never allow either side or end of camper to be more
than 4˝ out of level (f i g 2 and 3).

1. Remove the hand held remote control from its secure compartment.

2. Reinstall battery.

3. Unit is in a low power sleep mode when not in use. To activate the
unit, press the “WAKE” button on the switch assembly. The unit
will awaken and the red ACTIVE LED will illuminate. The unit will
automatically deactivate and enter sleep mode 10 minutes after the
last operation of the system.

4. When finished, the LED on the activation switch must not be lit.

5. Activate the RF transmitter by pressing the POWER+SELECT button.
The transmitter will power up and indicate the green LED.

6. The transmitter can be used to control either JACKS or
ACCESSORIES. When the green LED is active, the transmitter is
controlling JACKS. When the yellow LED is active, the system is
controlling the accessory motors.

7. When controlling jacks, the following operations are possible.

• Extension or retraction of an individual jack.

• Extension or retraction of all 4 jacks.

• Paired operation - adjacent jacks can be operated simultaneously

by holding down two jack buttons.

8. When controlling accessories, only one accessory may be powered at
a time. Multiple accessory button presses are ignored.

OPERATION:

Associate the transmitter with the base receiver:

• Power the system by pressing the WAKE button on the activation

switch (Q). The red ACTIVE LED should blink 2 flashes with a
pause. This indicates that the system is in the default shipment
state, and has no RF transmitter associated with it.

• Power the RF transmitter by pressing the POWER+SELECT button.

The green LED on the transmitter will illuminate. The transmitter will
remain powered for 1 minute.

• Hold down the WAKE button on the activation switch (Q) for 10

seconds. The system will enter LEARN TRANSMITTER mode which
is indicated by the red ACTIVE LED flashing quickly. In this mode,
the base receiver will associate itself with the next transmitter that is
received.

• Press any jack button on the transmitter. The base unit will see the

transmitter and associate itself with it. At this point, the red LED
should be on solid, and the blue LED will indicate detection of
transmitter RF signal.

m caution

• Do not over-extend or over-retract jacks. The electric jack has an

internal slip clutch to help prevent damage; when clicking sound is
heard, release switch. Continuing to hold the switch will wear out the
slip clutch or cause damage to the motor.
