Instructions:
- Power Supply: Connect the positive lead to the power supply within the operating voltage range (3V to 12V DC). Connect the negative lead to ground.
- Frequency Tuning: The buzzer operates at a fixed frequency of 3.2kHz ± 0.5kHz. No external tuning is required.
- Mounting: Secure the buzzer using the soldering tabs. Ensure that the connections are soldered properly to avoid any mechanical stress on the leads.
- Environmental Conditions: Operate the buzzer within the specified temperature and humidity ranges to ensure reliable performance.
- Storage: Store the buzzer in a dry environment with temperatures between -40°C and +85°C and relative humidity between 20% and 90% RH.
- Handling: Handle the buzzer with care to avoid damage to the piezoelectric element. Do not apply excessive force or bend the leads.
- Testing: To test the buzzer, apply the recommended operating voltage and listen for a clear, consistent sound. If the buzzer does not produce sound, check the connections and power supply.
