5.1 O-ring Care

Proper O-ring maintenance is crucial for maintaining the waterproof seal of your diving light.

1. After each dive, rinse the light thoroughly with fresh water.
2. Carefully remove the Tail Cap and inspect the O-rings for any dirt, sand, hair, or damage. Use the provided O-ring removal tool if necessary.
3. Clean the O-rings and the O-ring grooves with a soft cloth.
4. Apply a thin layer of silicone grease to the O-rings.
5. Replace any damaged O-rings with the provided spares.
6. Ensure the Tail Cap is screwed on tightly and evenly before diving.

5.2 Automatic Overheating Protection

Figure 6: Automatic Overheating Protection

The Smart Focus 2500 has a built-in automatic protection function against overheating. If the ambient temperature exceeds 50°C (e.g., when used out of water for extended periods), the light will automatically reduce its brightness to 20% to prevent damage to internal components. This is a normal safety feature.

5.3 సాధారణ సంరక్షణ

• ఉపయోగంలో లేనప్పుడు కాంతిని చల్లని, పొడి ప్రదేశంలో నిల్వ చేయండి.
• Avoid exposing the light to direct sunlight for prolonged periods.
• Do not attempt to disassemble the light beyond removing the tail cap for battery access.

6.1 Light Does Not Turn On

• Check if the battery is properly installed and fully charged.
• Ensure the tail cap is securely tightened.

6.2 Light Dims Automatically

• This is likely the automatic overheating protection activating. If the light is used in high ambient temperatures (above 50°C), it will reduce brightness to 20% to protect components. Allow the light to cool down.

6.3 నీటి లీకేజ్

• Immediately turn off the light and remove the battery.
• Inspect the O-rings and their grooves for any debris, damage, or improper seating.
