**Design and Construction:**
- The device is made with AlGaInP on a GaAs substrate Light Emitting Diode for a bright and long-lasting green light.
- Electrostatic discharge and power surges can damage the LEDs; it is recommended to use a wrist band or anti-electrostatic glove when handling.
- All devices, equipment, and machinery must be electrically grounded.

**Packaging & Label Specifications:**
- The DA04-11CGKWA is carefully packaged to ensure safe delivery and storage, with detailed specifications and instructions for use.

**Soldering and Cleaning Recommendations:**
- Through-hole displays are incompatible with reflow soldering.
- Mild "no-clean" fluxes are recommended for soldering.
- If cleaning is required, Kingbright recommends washing components with water only, avoiding harsh organic solvents that may damage the plastic parts.
- The cleaning process should be at room temperature, not exceeding one minute of wash time.
- After water cleaning, excess moisture should be removed immediately with forced-air drying.

**Circuit Design Notes:**
- Protective current-limiting resistors may be necessary for operating LEDs within the specified range.
- LEDs in parallel should each have their own current-limiting resistor.
- The driving circuit should protect the LED against reverse voltages and voltage spikes during power-up or shut down.
- The safe operating current should consider the maximum ambient temperature of the operating environment.
- Prolonged reverse bias should be avoided to prevent metal migration and potential leakage current increase or short circuit.

**Precautionary Notes:**
- The information in this document is for technical reference and represents typical usage scenarios.
- Part numbers, types, and specifications are subject to change without notice. Customers should refer to the latest datasheet before production usage.
