BUZZERS

Do not reconfigure the buzzer.

Sound pressure changes depending on the shape of the part to be installed in a device, or the installation location. Check the buzzer in

the mounted condition.

The buzzer has polarities.

When installing, be careful not to make a mistake with the polarities. Incorrect polarities will cause the following irregularities.

• Without circuit type: differences in sound pressure will be created.

• With circuit type: no sound will be generated.

Frequencies other than the rated frequency will change the characteristics (sound pressure), and may cause wide unevenness.

As the buzzer uses a magnet, it generates a surrounding magnetic field.

When designing a device, etc., confirm that there are no irregularities due to the magnetic field.

Check the buzzer in the mounted condition, and take measures such as shielding, etc.

The characteristics of the buzzer may change because of the influence of an outside magnetic field.

Because of deterioration or damage, maintain in rated storage temperature range, avoid environments where there are sudden temper-

ature changes, direct sunlight, corrosive gases and dust, and store wrapped in order to avoid applying stresses.

High safety and reliability is needed, and or, there is fear that failure, wrong movement, failure of product damages and worldly goods

etc related to life and health of people, or do not use for equipment(as nuclear power equipment-?automobile?-aircraft-?medical?

device) with fear that significant influence is had socially.
