Introduction
The AutoFlagger®Automated Flagger Assistance Devices (AFADs) were designed to conform, as
closely as possible, to existing flag-person based flagging operations. The physical
characteristics, including the octagonal STOP silhouette and triangular SLOW insignia, are
common to all existing traffic control flagging situations. This helps motorist acclimate to a new
traffic control device quickly and easily.
The physical size of AutoFlagger®allows it to be seen and recognized earlier in the construction
zone and aids motorists in visually differentiating it from other construction devices. Its’ height
makes the information discernable by cars positioned further away from the construction zone
than is possible by conventional flag-persons. Its’ gate arm further reinforces the stop message.
Its’ wide, stable trailer was designed to afford construction zone workers all possible means of
safety. Individual warning horns located on each sign head can be remotely activated to alert
workers of impending danger. The red and amber strobes provide additional confirming sign
position feedback to the operator and others between the signs, as well as enhancing visual
information to the motorist.
AutoFlaggers®are ideally suited for use on two lane, low volume roadways. Bridge repair,
pavement repair, utility work and roadside maintenance are typical uses of the devices. They can
also be quite useful during incident management, and using a single unit in conjunction with a
flagger can make an effective moving lane closure.
This manual covers all the essentials of the use and care of the AutoFlagger®. It is divided into
sections so that the reader may choose to read only those sections relevant to him or her. The
following table summarizes the sections:

Getting Started
Prior to operating in an actual work zone:
The AutoFlagger®is shipped fully assembled and ready to operate. The persons operating the
device should do the following before attempting to use it in a work zone:
•Familiarize themselves with coupling and uncoupling the trailers.
•Raise and lower the solar panel.
•Release the sign head transport lock, column brake, and raise and lower the head (see
below).
•Familiarize themselves with the STOP/SLOW manual override buttons, and ON/OFF
buttons located on the keypad on the back of each sign (see below).
•Open and close the front cover and understand the secondary catch.
•Understand the sign position lock using the column brake.
•Locate and switch ‘remote hand-held transceiver’ batteries from remote to charger.
•Familiarize themselves with the overall operation and control of the system.

Sign Head Set Up and Basic Operations
After raising solar panel:
•Release column brake.
•Disengage transport lock.
•Depress the ON button momentarily. The sign head computer will boot in about 3
seconds.
•Rotate head to front position (facing traffic).
•Open front cover.
•Raise/Lower sign head.
•Use lock ring to secure front cover to column.
•CAUTION: Be sure to release lock ring from cover before lowering head and watch that
the cover does not strike base of column.

Hand-Held Defaults and Set Up Options
Getting Started - Defaults
•Press and hold PWR button momentarily (about ½ second), then release. Allow
several seconds for the computer to boot.
•Select back light option. Depressing the STOP button turns the backlight OFF.
Depressing either of the SLOW buttons leaves the backlight ON.
•If both AFAD sign heads are turned ON, you will see one of the following
graphical depictions of their positions. Note that the default condition
disallows both signs from reading SLOW simultaneously.
OR

•Both signs must be in the STOP position before either sign can be
commanded to its’ SLOW position.
•As a sign is changing positions, the graphics will morph as shown below.
•NOTE: The auxiliary lights positioned on the sign heads display 3 distinct
positions.
oAmber indicates that the sign is in the SLOW position.
oRed indicates that the sign is in the STOP position.
oThe absence of either light indicates that the sign is in the process of
changing positions.
•If communication between the hand-held transceiver and the sign heads is
lost, the graphical STOP/SLOW will change to ‘dashes’.
Set Up Options
•Set up options are accessed by first depressing the MODE button (see examples
below).
•Scroll up or down by using the Up/Down keys to select the function you wish to
change.
•Depress the ENTER button to make changes.
•Depress the MODE key a second time to exit the set up screens and return to the
operating screen.

Example 1: to Swap Sign Sides
•Depress MODE to see the following display; and use the up/down arrows to
toggle between choices.
•When ‘SWAP SIGN SIDES’ is selected, depress the ENTER key to see the
following;
This changes which sign is displayed on the left and right sides of the remote, and is
intended to make it easier for the operator to remember which sign on the display
corresponds to which sign in the work zone. For example, having the AFAD sign to
the operator’s left correspond to the left sign on the hand held remote should help
avoid operator confusion.
•Depress the MODE key to exit to the operating screen.
UP ARROW
DOWN ARROW

Example 2: To allow both signs to read SLOW simultaneously,
‘INDEPENDENT’ (dump truck crossing) mode
•Depress the MODE key and use the DOWN ARROW key to select the ‘SET
SIGN MODE’ function.
•Depress the ENTER button.
•Scroll down to select the ‘INDEPENDENT’ mode, then depress the ENTER
button to activate that function.
•Depress the Mode button to exit to the operating screen.
•CAUTION: The ‘INDEPENDENT’ mode allows both signs to read SLOW
simultaneously. It should only be used in approved circumstances.
•Note: After powering down and re-powering the hand-held in the
‘INDEPENDENT’ mode, reselection of that mode is required.
Example 3: ‘SINGLE’ sign mode
•Depress the MODE key and use the DOWN ARROW key to select the ‘SET
SIGN MODE’ function. Then press ENTER.
•Scroll down to select the ‘SINGLE’ sign mode, then depress the ENTER button to
activate that function.
•Depress the Mode button to exit to the operating screen.
•In this mode, the hand-held transceiver will only communicate to one sign which
is the ‘first’ sign bound or connected to the hand-held as outlined in Example 4
below.
•If the hand-held is set to the ‘PAIRED’ or ‘SINGLE’ mode, that selection remains
active (regardless of a power down and re-power sequence) until the operator
changes it to another mode.
•READ THIS CAREFULLY: If you are operating two signs with two different
hand-held transceivers in close proximity to each other, connect or bind one hand-
held to only one sign. This will eliminate any chance of the hand-held controller
communicating to another, distant sign.

Example 4: Binding (connecting) hand-held remote control to Signs
•General Overview
Each hand-held transceiver and each sign head have a unique I.D. hard-coded into
their microprocessors at the factory. An operator can select one or two signs and
connect or bind a hand-held to them either in the yard, or on the job. The hand-
held will only bind to the sign(s) assigned to it in the following procedure.
Sign Binding Procedure
•Turn ON sign 1 only. Turn ON hand-held and leave ON during entire procedure.
Depress the MODE key and use the DOWN ARROW key to select the
‘BIND/UNBIND SIGNS’ function. Then depress the ENTER button to move to
the next screen.
•Depress and hold the ENTER button again to bind the hand-held to that sign head
(loud warning horn on sign will sound for about 10 seconds as confirmation).
Leave hand-held turned on, turn OFF sign 1 and turn ON sign 2 then depress and
hold enter again to bind second sign to the same hand-held.
•After both signs are bound to the hand-held, scroll down to ‘DONE’ and depress
the ENTER button to complete the procedure.
•Signs may be unbound from a connected hand-held by scrolling down to the
’UNBIND ALL SIGNS’ and depressing the ENTER button.

Powering Down the hand-held Transceiver
•Depress the PWR button for about ½ second.
•Depress the STOP button.
Maintenance
If a grease fitting is present, grease the head mechanism yearly. One pump only, while
mechanism is rotating. Do not over grease.
The charger for the hand-held’s batteries (in the charging bay) draws a slight amount of
power continuously. When storing the AutoFlagger inside, or in the absence of sunlight
for periods of time greater than 45 days, use of a trickle charger will help keep the 12 volt
deep cycle batteries charged.
For longer hand-held battery life, we advise that you remove the battery packs from the
storage bay charger when storing the unit for extended periods of time.
.
The trailer should be maintained in accordance with generally accepted maintenance
procedures. Proper tire pressure and brake adjustment, if so equipped, is advised.
