For best service, please take a few minutes to review this manual before you call. 

 

This unit is RoHS (Reduction of Hazardous Substances) compliant. The components, including the 
solder used are all lead free. If you decide to do any modifications or internal repairs, you should use 
only lead free solder and lead free soldering tools. Lead free solder melts approximately 100 degrees 
higher than the old leaded solder, so you may need to upgrade your current soldering system.
