Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the operating range of 3V to 12V DC.
   • Connect the positive lead (red wire) to the positive terminal of the power supply and the negative lead (black wire) to the ground.

2. Installation:

   • Solder the leads to the appropriate terminals on your circuit board.
   • Ensure the buzzer is securely mounted to avoid mechanical stress on the leads.

3. Testing:

   • Apply the rated voltage to the buzzer and verify that it produces the expected sound output.
   • Check the sound pressure level at a distance of 10cm to ensure it meets the minimum requirement of 85dB.

4. Environmental Considerations:

   • Operate the buzzer within the specified temperature and humidity ranges to ensure reliable performance.
   • Avoid exposing the buzzer to condensation or extreme environmental conditions.

5. Handling:

   • Handle the buzzer with care to avoid damaging the piezoelectric element.
   • Do not apply excessive force or torque to the leads during installation.

6. Storage:

   • Store the buzzer in a dry, cool place within the storage temperature range of -40掳C to +85掳C.
