Version 2: Wholesale FAQ (Focus on Compatibility & Orders)

1. What plug types can you supply?

We manufacture this model with US, EU, and UK standard plugs. The internal PCBA supports wide voltage (110V-240V), so the same unit works safely in 110V countries (like USA/Japan) and 220V countries (like Europe/Asia).

2. How does the code matching work for inventory management?

The units come pre-paired. However, they use a "Learning Code" system.

• To Pair: Hold the volume button for 3 seconds, then press the transmitter.

• To Clear Code: Hold the volume button for 10 seconds.
  This allows end-users to mix and match sets easily without returning products.

3. Can I customize the melody selection?

The standard chip comes with 32 popular melodies (Ding-Dong, Westminster, etc.). For very large OEM orders (MOQ 3000+), we can customize the music chip with specific sound files.

4. Is the packaging suitable for online shipping?

Yes. The product is compact and durable. We can provide it in a sturdy neutral kraft box (brown box) which is crush-resistant and perfect for Amazon FBA or shipping labels, saving you the cost of extra repacking.

5. What is the waterproof rating?

The transmitter is designed with a gap-tight structure suitable for outdoor use (rain splash resistant). While often marketed as waterproof, we recommend listing it as IP44 Weather Resistant to be technically accurate and manage customer expectations for heavy storms.
