How to Use the Replacement LED 20mA 3.5V 70mW
- Switch off the instrument and disconnect it from the power supply.
- Confirm that the original LED rating matches 20mA, 3.5V and 70mW.
- Check the LED polarity before fitting it into the circuit.
- Install the LED using the correct mounting or soldering method for the equipment.
- Reconnect the power supply and test the LED at the correct operating voltage.
- Stop use immediately if the LED overheats, flickers or fails to illuminate correctly.
Use only in compatible low-voltage circuits, and do not exceed the specified electrical rating.
Care & Maintenance
- Store LEDs in dry, dust-free and anti-static-safe conditions where possible.
- Do not bend leads repeatedly, as this may weaken the connection.
- Avoid reverse polarity, excess voltage and uncontrolled current.
- Keep spare LEDs labelled with voltage and current ratings for safe maintenance use.
