2. Setup Instructions

2.1 Verifying Compatibility

Before using the charger, it is crucial to verify its compatibility with your smartwatch. This charger is designed for smartwatches that utilize the "Veryfit" or "Da Fit" applications and have a 2.54mm pin spacing between the two charging contacts.

1. Measure Pin Spacing: Carefully measure the distance between the centers of the two charging pins on the back of your smartwatch. Ensure it is approximately 2.54mm.
2. Check App Compatibility: Confirm that your smartwatch uses either the "Veryfit" or "Da Fit" companion application.

Figure 2.1: Smartwatch charging pin spacing measurement (Note: Image shows 2.84mm, but product is 2.54mm compatible. Please verify your watch's specific spacing).

Important Note: The product includes two chargers with opposite electrical polarities (Black: N+ -S, White: N- +S). Due to this, typically only one of the two provided cables will work with your specific smartwatch. Test both cables to determine which one is compatible.

2.2 Connecting the Charger

1. Power Source: Plug the USB-A end of the charging cable into a compatible USB power source. This can be a computer's USB port, a laptop, a wall adapter (5V/1A recommended), a car charger, or a power bank.
2. Smartwatch Connection: Align the magnetic charging pins of the cable with the charging contacts on the back of your smartwatch. The magnetic connection will automatically secure the charger in place.
3. Verify Connection: Ensure the smartwatch displays a charging indicator (e.g., battery icon with lightning bolt, charging animation) to confirm a successful connection.
