Page 3: Information About Lead-Free Soldering
To avoid wear-out of tips switch off un-used equipment, or reduce heat. • Mix of lead-free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoid mixed solder alloy types (leaded and lead-free). -

Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz). -
