Handling Notice
- Please don't touch the component with the bare hand, because electrode maybe corroded.
- Avoid excessive pulling lead wire because wire may break or soldering point may come off.
- The circuits utilizes transistor switching. The circuit constants for heft of the transistor are optimally chosen to maintain stable, so please follow it when you design a circuit.
- Magnetic sounders are driven by an input frequency; the given frequency characteristics can be obtained only when applying 1/2 duty square wave (Vb-p). The end-users must know the facts that the characteristics of frequency may be quite changed in different shapes with the applied various waves, like sine wave, square wave (Vb-p) or other waves.
- When other voltages are applied than the recommended one, the characteristics of frequency will also be changed.
- Please keep proper distance from strong magnetic fields when storing, transiting, and mounting.
Soldering and Mounting
- Please read the HYDZ specification if soldering of the component is needed.
- Washing of the component is not acceptable, because it is not sealed.
- Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.
