INTRODUCTION
The K&K Systems’Message Signs are mobile changeable message signs that are
mounted onto a service vehicle or a trailer with winch type or hydraulic lift. They
utilize energy ecient LED displays and the latest and most ecient solar panels
to display your message brightly and continuously during the day, night in any
weather condition.
All units are completely setup and ready for use. Program your message using
wireless connectivity and the K&K cloud-based CrossTalk software, Bluetooth
connected tablet with installed software, or the on-board qwerty keyboard. Super
bright LED technology with 100,000 hour rating displays alphanumeric text and
full matrix graphics with quick message selection switch.
K&K’s units are fabricated from aluminum with a at black powder coat nish to
give a smooth look and prevent rust.
The standard Vehicle Mounted Message Sign features a folding frame operated by
an actuator. The message sign folds out automatically when the unit is powered
on, and automatically folds down when the unit is powered o for when the
vehicle is moving. Maintenance of internal parts is made easy with the front door
access design. Vehicle Mounted Message Signs are available in your choice of one-
line, two-line, and three-line with mounting options and sizes to meet your needs.
Should K&K not have a system that meets your needs, we will custom design a
system to meet your specications

MESSAGE SIGN
The display housing is framed in extruded
aluminum and has a Lexan face that provides
UV protection along with glare resistance. The
message sign uses LED (light emitting diodes) to
produce text and images.
Your Trailer Mounted Message Sign provides messaging
functionality to display predened and custom messages
text. Full Matrix Message Signs can also display MUTCD
graphics and animations. To catch motorists’attention
we include an option to make the message ash.
COMPONENTS
TRAILER MOUNT POWER SOURCE
Our products incorporate a battery pack wired for 12 volt operation. The number
of batteries may vary depending on the requirements of the design. The system
comes standard with four (4) 12 volt sealed batteries, totaling 400 amps, or two
(2) 12 volt batteries, totaling 200 amps. The units come with 140 watts of solar,
standard. The battery bank is regulated and protected by a solid-state charge
controller/low voltage disconnect that is built into the CrossTalk. This prevents
gassing and over discharging of the batteries, which can result in premature failure.
VEHICLE MOUNT POWER SOURCE
The truck mounted message board comes standard with a 25ft power cable that
is to be integrated into the vehicles existing power system. The smart controller
prevents the message board from draining the vehicles battery while it is in the
OFF mode during storage. The arrow board is designed to be operated while the
vehicles engine is on, to prevent the draining of its battery, but can be operated
sparingly while the vehicle is o.
TRAILER BATTERY BOX
The ventilated battery box is steel fabricated with a top
mount lid that is sealed with hardware to protect the
batteries, charger, and hydraulic system.
CONTROL BOX AND CONTROLLERS
The control box contains the control panel, on/o switch, main processing unit,
keyboard and solar charge controller, Bluetooth tablet, and CrossTalk Controller.
The control box is constructed of heavy duty aluminum and is weatherproof to
protect its components.

Regular Font Style Bold Font Style Graphics/Animations
TRAILER
The trailer is fabricated from tubular steel
with a tubular steel axle. It is powder
coated with safety orange, black or white.
Custom colors are available upon request.
Adjustable jacks are mounted at each
corner of the trailer. The tongue features
a wheeled jack. The taillights are dual
combination reective lights with stop, tail,
and turn signal. Trailers come standard with
ve lug appropriately sized wheels and tires.

PRECAUTIONS, SAFETY, AND
MAINTENANCE
The following are K&K Systems’recommendations for safe and responsible use.
Please remember that the best assurance against accidents is a careful and responsible operator.
PRECAUTIONS
Inspect your unit upon delivery. Wires and plugs may have loosened during
shipment which will cause operational issues. Even though the system arrives
ready to run, inspect all components and test before installation. Test the unit
before installation for convenient working conditions.
• Periodically inspect the trailer and/or unit. This includes but not limited to wheels,
tongue, pins, safety chains, taillights, nuts, bolts, cable clamps, etc. Tighten, repair,
or replace when and where necessary.
• O-load trac cones and barricades prior to message sign deployment.
• The trailer should always be properly setup and leveled with the jack stands
before the message sign is raised.
• Always use safety chains and properly sized hitch ball when towing the unit.
• Always tow trailer units in the down position.
BATTERIES
The batteries are sealed. Check all terminals for proper connection, tightness,
and corrosion. Check the battery condition and charge when necessary or after
storage. It is recommended that the batteries be charged every 3 to 6 months,
regardless of weather conditions. Use an apron, gloves, and safety glasses when
working on batteries. When the batteries have come to the end of their life cycle,
please dispose of them in accordance with your local laws and regulations.
BATTERY CHARGER SAFETY
The battery charger is preset in automatic position. DO NOT CHANGE THESE
SETTINGS because of possible overcharging of batteries. Plug cord into a standard
120 volt AC for charging.
SOLAR PANELS
During operation, keep the solar panel clean of excessive dirt and debris by using
only soapy water and a soft cloth or sponge. Periodically check the integrity of the
wiring connections in the junction box. Inspect for signs of damage to the solar
panel’s glass or frame.
MAINTENANCE
• K&K recommends that the user clean the solar panels every 6 months. Over time
the solar panels may build up a thin layer of dust/dirt/road grime that can
adversely aect their eciency signicantly.
• Check the battery every 6 months to ensure proper charging. If below 12.3 volts,
charge to keep power reserves high. Check solar system by cleaning the panel
and inspecting wiring for wear and secure connection.
• Check that the mounting is secure and has not shifted as the solar panel may shift
direction over time. Ensure the panel is facing South.
• Check the system a few days after installation to ensure proper charging and
operation.

TOWING AND
LONG-TERM STORAGE
TOWING
Failure to follow these instructions exactly can cause hitch ball failure or loss of trailer
attachment resulting in a vehicle crash and/or personal injury.
Use the hitch ball only for towing trailers or vehicles connected to the ball with a socket-type
coupler. The ball diameter must match the coupler socket size. Do not exceed the gross
trailer weight shown on the ball.
Improper tightening can cause hitch ball failure or loss of trailer attachment.
• The threaded shank must protrude beyond the bottom of nut when tightened. If it does
not, the ball shank is too short for the application and loss of attachment may occur.
• Check the nut tightness every time you hook up the trailer and at the beginning of each
towing day. Tow only if the nut is tightened as specied.
• Replace any damaged or worn parts (except nish).
• Never attach a tow rope, chain, or stretch type elastic rope to the hitch ball.
• Do not fasten the trailer safety chain or any other type of attachment to or with, the ball.
• Lubricate the ball and coupler to minimize wear and friction. The coupler must not bind on
the ball.
This product complies with V.E.S.C. Regulation V-5, C.S.A. Standard D-264 and the Safety
Specications and Requirements for Connection Devices and Towing Systems.
TRAILER MOUNT LONG-TERM STORAGE
When the sign is to be stored for extended periods of time, it is recommended to store the
unit outdoors and in a sunny area to allow the unit to maintain the charge on the batteries.
If it is to be stored indoors, keep the unit plugged into the AC charger when possible. When
the sign is to begin operation again, a thorough inspection of all systems is advised before
the sign is towed to the job site. Check the battery state of charge to conrm over 12 volts.
VEHICLE MOUNT LONG-TERM STORAGE
