2. Safety Information
- Do not use indoor TVs in humid and high-temperature outdoor environments. This SYLVOX TV is specifically engineered for outdoor conditions.
- Ensure proper ventilation. Due to its brightness and heat output during operation, flush mounting is not advised. Allow at least 4 inches of clearance around the perimeter and on the back of the TV to facilitate heat dissipation and prevent damage.
- Operating temperature range: -22°F to 122°F (-30°C to 50°C). Prolonged exposure to direct sunlight may cause the surface temperature to reach 194°F (90°C). If the TV displays abnormalities in high-temperature conditions, turn it off until it returns to the normal operating range. Consider providing shade to extend the TV's lifespan.
- The TV is IP55 waterproof, designed to withstand rain and dust. However, a TV cover is recommended for prolonged periods of extreme weather or non-use to further protect the unit.
