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 change in different shapes with the applied various waves, like sine wave, square wave (Vb-p) or the other waves.
- When other voltage are applied than recommended one, the characteristics of frequency will be also changed.
- Please keep proper distance for strong magnetic field when you storing、transiting and mounting.
Soldering And Mounting
- Please read of HYDZ specification, if soldering component is needed.
- Washing of the component is not acceptable, because it is not scaled.
- Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.
