(Radiance 10 Units only)
• Cycle the main power switch to reset machine and verify operation
• Call Technical Service if issue not corrected
(Communications issues can occur due to Electro-Magnetic Interference at a particular installation. A dedicated power circuit for the
unit is required. However, the equipment that is installed near the machine can also be affecting the communications.)
