Features

• Reduction by power consumption of approximately 35% as compared with conventional products, contributing to low power consumption of a set.
• Eliminating the DC/DC converter so far needed for conventional system due to 1.5 V single power supply, and reducing approx. 40% of external components. This contributes to space saving in a set.
• Built-in standby switch to reduce consumption current considerably. Seating plane 0.15
