Setup and Installation
Proper installation ensures the sign's effectiveness and longevity. The sign is designed for easy mounting on various surfaces.
Mounting Instructions:
- Prepare Mounting Surface: Ensure the surface (U-channel post, square or round galvanized post, wooden post, or chain-link fence) is clean and stable.
- Align Sign: Position the sign at the desired height and location. The sign features pre-drilled 3/8 inch holes for convenience.
- Secure Fasteners: Use appropriate fasteners (not included) such as bolts, screws, or zip ties, depending on the mounting surface, to secure the sign through the pre-drilled holes. Ensure the fasteners are tightened sufficiently to prevent movement but do not overtighten to avoid damaging the sign.

Operation
The SmartSign "Speed Limit 5 MPH" sign operates passively by clearly displaying the speed limit. Its primary function is to provide visual communication to drivers and pedestrians, promoting safety and adherence to designated speed zones.
Visibility:
- Daytime: The bold black text on a white background ensures high contrast and readability in daylight conditions.
- Nighttime: The 3M High-Intensity Grade reflective material significantly enhances visibility in low-light conditions and at night when illuminated by vehicle headlights. This ensures the sign remains effective 24/7.

Troubleshooting
While the SmartSign is designed for durability, here are some common issues and their potential solutions:
| Issue | Possible Cause | Solution |
|---|---|---|
| Reduced Reflectivity at Night | Dirt, grime, or debris on the sign surface. | Clean the sign surface thoroughly with mild soap and water. |
| Sign Appears Loose or Wobbly | Loose mounting hardware or damaged post. | Check and tighten all mounting fasteners. Inspect the mounting post for damage and repair or replace if necessary. |
| Fading or Discoloration | Extreme prolonged exposure to harsh UV rays (unlikely due to UV laminate). | While highly resistant, extreme conditions over many years might cause minimal fading. No direct solution other than replacement if significant. |
