Best Practices for Radar Speed Sign Installation
These guidelines and recommendations provide the best practices for radar speed sign installation to assure
successful, accurate and effective traffic calming.
• The radar speed sign should be installed no more than 5 feet from
the road curb. At more than 6 feet from the road, the sign will take
the eyes of the driver an unsafe distance from the roadway, and will
result in displayed speeds that are LOWER than the actual speed
• Do not install the radar speed sign in a curve or after a curve.
The sign should be installed in the straightaway of the road. A radar
speed signal cannot “curve” with the road, and will not display
speeds with enough time for drivers to see the alert and adjust their
speed.
• The sign should be positioned perpendicular to the road with the
radar pointing directly at the curb, not at the center of the road, for
maximum vehicle detection. Signs rotated toward the center of the
road will not perform as well.
• Do not install a solar powered radar speed sign under a tree.
Summer leaves on the tree could impact solar recharging. Make
sure the solar panel is installed facing as close to South as
possible. (solar models only)
• The radar speed sign should be installed on the same side of the street as oncoming traffic. If installed on the wrong
side of the road, the angle of the sign could result in poor
detection of the on-coming traffic, and also result in the sign displaying speeds of vehicles travelling in the opposite
direction.
• The radar speed sign should be installed 7-10 feet off the ground. Do not install the radar speed sign lower than
4 feet off the ground. Doing so will result in much of the radar speed signal being absorbed by the road, reducing
your detection range.
• Prior to the radar speed sign installation, look for any obstructions (telephone poles, large tree limbs, other signage,
etc.) that might interfere with proper operation of the sign.
• Installing the sign on the same side of the street as parallel parking of vehicles could affect the radar performance of
the radar speed sign. The radar speed sign should be installed high enough off the ground to detect oncoming traffic
over the parked vehicles.
• If the radar speed sign is installed more than 12 feet above the roadway the sign should not be tilted more than 3°- 4°
downward to detect vehicles. Doing so will result in a greatly reduced length of time vehicles will be detected, and will
display speeds that are LOWER than actual speed. (the cosign effect).

Best Practices for Radar Speed Sign Installation
Our signs are designed to be water resistant when vertically installed and mounted properly on an approved pole or
mounting surface.
• Prior to installation the sign should be stored inside in a cool, dry place.
• Do not store the sign outside.
• Do not store the sign in a horizontal position. Storing the radar speed sign horizontally outside where it is exposed
to the weather voids the warranty.
• Do not leave the sign in a truck bed or laying on the ground.
• Do not drop the sign.
• Do not leave the sign in storage for months. The batteries will naturally discharge and will damage the batteries.

Best Practices for Use of the TC-400
These guidelines and recommendations provide the best practices for the use of the TC-400.
Installation:
• Utilize multiple Go Brackets: To create a traffic calming circuit, install Radarsign Go Brackets on existing poles
at multiple locations. This enables personnel to quickly and efficiently relocate the TC-400 to areas in need of traf-
fic calming in a regular rotation. The signs can then be moved with NO TOOLS, just a key is required.
Batteries
• Initial charge: To ensure your batteries have full charge, use the enclosed charger to charge both battery packs
before deploying the radar speed sign. An initial charge time of 6 hours at room temperature for each is
recommended.
• Order extra batteries: One set can be charging, ready to replace a depleted set at a moment’s notice. One set of
backup batteries can serve multiple Radarsign devices.
• Preserve battery power: To get a longer life from you power source, set the feedback device to turn off during
overnight hours if traffic in that location is minimal. Also set the minimum display speed at, or slightly below, the
speed limit of the road. For example, if your street has a speed limit of 30 mph, set the minimum display speed no
lower than 25 mph. Setting the speed limit at 10 mph will turn the display on for virtually all traffic, and simply run
the battery for people who are not speeding.
• Preserve battery life: Be sure to store and charge batteries in a temperature controlled environment. Charging
and storing the batteries outside in the cold and hot temperatures will diminish the overall life and performance of
the battery packs.
• Maintenance: Batteries will generally last for 5-7 years if regularly charged. Do not wait until your batteries are
completely exhausted to recharge.
Data Collection and Reporting (optional)
• Operate in stealth mode first: A suggested strategy for initial TC-400 deployment would be to operate in stealth
mode (feedback display off) for up to one week; then turn the feedback display on for one week. Using the
Streetsmart traffic data reporting program (optional), take the data collected from the sign, and compare the infor-
mation from both weeks. This will give you a baseline of the speeding problem (week one). It will show you the
overall effect of the radar sign alert display on the speeds of drivers. It will also show the time of day and day of
week that speeding is the worst. You can see how many drivers are more than 5 mph over the speed limit, how
many are more than 10 mph over the speed limit, and how many are 15 mph over the speed limit. This infor-
mation can be used to deploy police resources intelligently.
• Share the data: Sometimes law enforcement officers deploy a radar speed sign to a neighborhood based on citi-
zen complaints about speeding. Officials often learn that, despite resident reports, drivers are actually complying
with the speed limit. Historically, a citizen’s evaluation of vehicle speed tends to be quite inaccurate. Still, residents
are concerned about the safety of their pets and children. To alleviate their fears and build goodwill within the com-
munity, share what the StreetSmart data has revealed. This can be done via social media or through a direct per-
son-to-person visit. If the data reveals a speeding problem that needs further action, share that information as well,
along with the agency plan for addressing the problem.
Implementation
• Establish goals and criteria. Whether it be sub-arterial roadways, school zones, or neighborhood streets, decide
in advance how and where your Radarsign TC-400 will be used. These devices will become quite popular among
citizens and business owners so you can expect significant demand for their use. Establish your community
guidelines and remain consistent.
• Some issues to consider when establishing usage parameters:
• The number of speeding violations or speeding-related accidents in the area
• The number of pedestrians
• The number of vehicles traveling on the street
• Use the Maximum Speed Cutoff option to discourage “sign racing.”

TC-400 Installation Instructions
Contents of your Model TC-400:
➢ 1 radar and display housing with YOUR SPEED faceplate
➢ 1 battery housing
➢ 2 lithium iron battery packs
➢ 1 AC battery charger
➢ 2 keys on Radarsign keychain (used to lock the radar speed sign display to the battery housing).
The keys are attached to the sign handle.
➢ 1 Go Bracket (stainless steel) for mounting your radar speed sign on existing poles
➢ 1 set of mounting hardware for your Go Bracket; Contains 2 stainless steel carriage bolts (3" long) with lock
washers and nuts
TC-400 Installation Process:
Using the keys attached on the housing handle, open the TC-400 cabinet and remove the radar speed sign from the
housing by lifting off the hinges.
1. Remove the packaging, the battery charger, and the batteries from the
battery housing.
To ensure your batteries have full charge, use the enclosed charger to charge
both battery packs before deploying the radar speed sign. An initial charge
time of 6 hours at room temperature for each is recommended. If the
charger light turns green sooner, that is OK too.
Maintenance Note: Batteries will generally last for 5-7 years if regularly
charged.
Do not wait until your batteries are completely exhausted to recharge.
2. Remove the Go Bracket from the back of the battery housing.
3. Mount the Go Bracket to your existing pole. The hardware included should
allow you to mount the bracket to a 2" x 2" square post, or a U-Channel
post. The Go Bracket is a universal bracket, allowing for longer bolts, and
has slots for ½" pipe clamps, banding, or strapping material. (If the pole is
round or larger than the 3" bolt can support, please obtain a longer bolt, or
use a pipe clamp, banding, or strapping to mount the bracket. All are cus-
tomer supplied.)
Whatever method you choose, be sure to secure the bracket with the
hardware as shown in the photo to the right. This will provide you the
maximum protection against theft of the radar speed sign. The Go Bracket
is labeled TOP and BOTTOM. When installing, make sure you mount the
bracket with the top side up.
Many users will purchase additional Go Brackets and leave them on existing
poles around town. They are small and unobtrusive. This allows the owner
to create a circuit to rotate the radar speed sign on a regular basis, multiply-
ing the value of your investment. Mounting and un-mounting the radar
speed sign can be completed in about 1 minute, with NO TOOLS!

4. Mount the battery housing on the Go Bracket,
securing it with 2 of the screw knobs (black
handle with red center) provided. A third spare
is included with your housing. If using banding
clamps, make sure the driver cam is inside
the battery housing.
5. Insert and secure the battery packs into the
battery housing with the Velcro strapping as
shown.
6. Connect the battery pack(s) to the radar speed
sign power cord.
7. Mount the radar speed sign display on the
hinges on the battery housing.
8. Connect the battery power cord to the back
of the radar speed sign display housing.
One (1) battery pack should provide
approximately 5-7 days of operation of
the radar speed sign. With two battery packs,
you should get approximately 10-14 days of
operation of the radar speed sign. With colder
temperatures, the operation time will drop
proportionately.
Each battery pack will need 12 hours to fully re-charge.
You may prefer to purchase an additional battery pack to operate the sign while
your 2 other packs are being re-charged.
9. Lock the front of the radar speed sign to the battery housing by pushing in the
lock mechanism until you hear a click and the lock is flush
with the side of the housing.
