SAFETY PRECAUTIONS FOR USING TDK Electromagnetic Buzzer——SD1209T3-A1
Please be sure to read the specifications of TDK Electromagnetic Buzzer before use.
1. Please pay sufficient attentions to the warnings for safe. designing when using the buzzer. Incorrect usage may cause smoke or fire.
2. Do not make sound on the buzzer when it is close to ears. Listening to the buzzer when it is close to ears, or continuant lis tening to it for an extended period, may result in hearing disor ders. Thoroughly warn consumers not to turn on the sound when the buzzer is close to ears.
3. Do not exceed the rated operation voltage range when using the buzzer. If it is exceeded beyond the rated operation voltage, a built-in coil may generate heat, resulting in deterioration of the coil, which may cause a drop in sound pressure or a change in the terminal resistance value. If a rare short circuit occurs due to heat generated in the built-in coil, a large electrical current flows to the equipment used, possibly causing it to emit smoke or fire.
4. The buzzer is a magnetic type sounder. Do not use it for any other purpose than a sound generation.
5. Do not use the buzzer in other than atmospheric air.
6. Do not use the buzzer in the following environments (excluding cases in which countermeasures are taken).
7. After installing the buzzer when designing an apparatus, confirm that there are no abnormalities by performing a reliability evaluation test.
