Troubleshooting Guide
If you experiencing a problem with your sign please refer to the troubleshooting guide below to diagnose any issues and resolve them prior to requesting a return. Often times it is a simple programming, installation, or maintenance issue, not a sign operation issue, that is preventing the sign from operating properly. Troubleshooting Guide PDF
Where do I find the serial number of my sign?
If you are in front of the sign, there is a label on the sign with the serial number:
- TC-400: The serial number label is located on the inside bottom left of the front housing
- TC-500: The serial number label is located on the side of the housing
- TC-600: The serial number label is located on the bottom of right outlet box on the back housing
- TC-1000: The serial number label is located on the side of the housing
If you are logged on the Radarsign wi-fi 10.0.0.1, the sign serial number is in the top right corner of the top of the screen. If there are multiple signs in the area, the serial number displayed is the sign you are connected to.
The Blue LED is not on at all. (Sign setting issue)
Is your Blinky Enabled box checked in sign settings?
Go to the Sign Configuration Settings > General Settings and make sure the Blinky Enabled box is checked.
If it is checked and the Blue LED is not on, then reboot the sign and see if you see a boot message (scrolling or flashing numbers).
To reboot disconnect all power connectors to the sign for 15 seconds:
- TC-400 battery models: Disconnect the three prong plug
- AC models: Disconnect AC power
- Solar models: Open the junction box at the bottom of the sign, disconnect BOTH plugs (2 prong solar plug and 4 prong battery plug)
Reconnect the power connections. After sign boots, if the blue light is not blinking, please contact Radarsign Customer Support via email (customerservice@radarsign.com) or by calling 678-965-4814 during normal business hours.
My sign is locked up - blue radar light is solid/not flashing (Power Issue)
The sign needs to be reset.
To reset the sign, run a 10 lb. pull magnet over the blinky blue light area to reset the sign.
If you do not have a magnet, disconnect all power connectors to the sign for 15 seconds:
- TC-400 battery models: Disconnect the three prong plug
- AC models: Disconnect AC power
- Solar models: Open the junction box at the bottom of the sign, disconnect BOTH plugs (2 prong solar plug and 4 prong battery plug)
Reconnect the power connections. If the blue light in not blinking, please contact Radarsign Customer Support via email (customerservice@radarsign.com) or by calling 678-965-4814 during normal business hours.
If you can connect to the sign, enter 10.0.0.1/reboot. After rebooting the sign, make sure the sign displays a boot message (scrolling or flashing numbers depending the model). Once you see the boot message, check your sign configuration.
The sign does not display the speeds of some or all of the oncoming traffic (Sign Setting Issue)
| Issue | Possible Solution |
|---|---|
| Is your DISPLAY ENABLED box checked in sign settings? | What are the minimum and maximum speed display settings for your sign? Are they too narrow for the road traffic traffic? Are they too high for most traffic? Are they too low for most traffic? Do you have any timers activated that might override the standard settings? |
| Have the sign BASIC SETTINGS possibly changed for the sign to the point where the sign has been confused and will not operate? | To correct, check your BASIC SETTINGS, TIMERS, and TRIGGERS. (Refer to the Radarsign Operation Manual basic settings instructions) Turn off (disable) all timers and triggers and see if the sign starts working. Ensure Display Enabled box is checked. Ensure Radar Enabled box is checked. Ensure some Display Content is enabled (speed minimum, speed maximum, and alerts). |
| Have you rebooted your sign? | TC-400 battery models: Disconnect the three prong plug for 15 seconds. When sign re-boots, you will see a boot message (scrolling or flashing numbers). When completed, the Blue LED in the center of the display will start blinking. AC models: Disconnect AC power for 15 seconds. When sign re-boots, you will see a boot message (scrolling or flashing numbers). When completed, the Blue LED in the center of the display will start blinking. Solar models: Open the junction box at the bottom of the sign, disconnect BOTH plugs (2 prong solar plug and 4 prong battery plug) for 15 seconds. Reconnect. When sign re-boots, you will see a boot message (scrolling or flashing numbers). When completed, the Blue LED in the center of the display will start blinking. |
The sign does not display the speeds of some or all of the oncoming traffic. (Power issue with solar/battery backup)
| Issue | Possible Solution |
|---|---|
| Is the sign a TC-400 battery model, a TC-600 solar model or TC 1000 solar model? If so, is the battery charged? | Do a battery test with Wi-Fi to see the battery charge level. Connect to the sign, then go to 10.0.0.1 and read the sign status at the top of the page. If the charge is less than 10 volts, then there is a problem with the sign charging the batteries. For the TC-600/TC-1000 if you get a reading close to 13.88, the batteries MAY not be connected. Double check the 4-prong connection in the bell box at the bottom of the sign. |
| If you have a solar powered sign, does your sign have a low battery charge? | The SIGN STATUS box at the top of the Home configuration page 10.0.0.1 will provide you the battery voltage. The sign will operate between 10.5v and 14v. A low-battery cutoff feature will protect the batteries from being run down to a near zero state. If your voltage reading is below 10.5v, the batteries need to be charged up. On this screen, under Display Configuration, disable the display by unchecking the Display Enabled box, AND under General Settings, disable the radar by unchecking the Radar Enabled box. This allows the batteries the best opportunity to re-charge. Select Set Configuration tab (at bottom of the screen) to enable these settings. Allow 2-3 days of sunny operation for batteries to fully recharge. Be sure to Enable Radar and Enable Display when re-activating the sign after the 2 day re-charge. If the batteries are completely dead, you will not be able to communicate or load the main config page to get battery readings without unplugging the batteries. Unplug the 4-prong battery charging connector (batteries) and the 2-prong solar power conduit connector. Then only plug in the 2-prong connector. Let the sign boot. Disable the display by unchecking the display enable box under display configuration on your main configuration page (10.0.0.1). After disabling the display, plug in the 4-prong connector and let the sign recharge the batteries. Recharging could take 2-3 days of good solar conditions. Once the batteries are charged, enable the display. |
| If you have a solar powered sign, is the solar panel operating correctly? | There must be direct sunlight on the solar panel from 10 am until 4 pm for it to charge the batteries. Solar panel performance will be affected by long stretches of extreme weather (snow, rain or cloudy days). Make sure the solar panel is clean and free of any debris. Solar panel performance will be affected by obstructions such as mold, mildew, leaves, snow, etc.). Keep the solar panels clean and free of dirt by washing with a mild detergent. Reboot the sign: Disconnect power from the sign for 15 seconds, and then reconnect power. |
| If you have a solar powered sign, is the solar panel wired properly? | Your solar panel may have been wired backwards. Confirm the positive (red) wire coming from the solar panel mates to the positive (red) wire coming from the sign. If you have a multi meter, set the meter to measure 24V or higher and check for power coming from the solar panel connector in the sign’s junction box. The meter should show +16V or higher in sunlight. If the reading is negative, the panel is likely wired incorrectly. If the wiring in the sign’s junction box is correct, check the wiring in the junction box on the under side of the solar panel. Connections should be clean and tight. You may need to re-crimp the solar connections. |
The sign is displaying two yellow horizontal lines for all traffic. (Sign setting issue)
Is your OVER MAX setting too low?
Check the sign configuration speed settings for OVER MAX. If max speed to display is too close to the speed limit setting, raise to 20 mph over the speed limit.*
*If Bluetooth® model, please contact Radarsign Customer Support via email (customerservice@radarsign.com) or by calling 678-965-4814 during normal business hours.
My solar sign only displays speeds occasionally OR my solar sign only works during the day, or not until 9 or 10 in the morning. (Solar panel installation issue)
Is the 4-prong connector in the small box at the bottom of your sign connected?
If not, then the batteries in the sign are not in the charge loop so the sign is running off solar power only, working when there is daylight and not working at night.
Connect the 4 prong plugs and reboot the sign.
The speed display is not activated until the vehicle is very close to the sign (less than 75 feet). (Sign installation issue)
| Issue | Possible Solution |
|---|---|
| Is the sign properly aligned to oncoming traffic? | Rotate the sign left or right up to 1 inch to see if the radar signal improves. If the road is not flat, use a couple of washers to tilt the sign to match the rise or fall in the road. |
| Is the sign installed more that 9 feet off the ground? | If > 9 feet, the signal may be skipping over most of the traffic. Use a couple of washers to tilt the sign down to pick up more traffic. |
| Is the sign installed on the same side of the street as parallel parking of vehicles? | If yes, raise the sign on the pole and tilt the sign down 2°- 4° to ensure the signal is not getting dispersed by the parked vehicles. |
| Is the sign installed in a curve or after a curve? | If yes, move the sign to the entrance of the curve, or to >150 feet after the curve. Radar cannot bend with the road. |
The sign is generating inaccurate speed readings (incorrect speeds, random speeds, or ghost speeds). (Sign installation issue)
Is something interfering with the radar signal? Does the Blue LED go solid with oncoming traffic?
Inaccurate readings can occur in certain environments. To avoid this possibility, do NOT INSTALL the radar speed sign facing any of the following:
- Large LED billboards or signage
- AC units with fans
- Large transformer
- Fan(s)
Some LEDs do not display when the screen is showing speeds. (Sign Installation Issue)
