TOP PREVIOUS NEXT 3 Precaution of Laser Diode TOP PREVIOUS NEXT CAUTION: This product utilizes a laser diode with the unit turned on, invisible laser radiation is emitted from the pickup lens. Wave length: 780 n

19、m Maximum output radiation power from pickup: 100W/VDE Laser radiation from pickup unit is safety level, but be sure the followings: 1. Do not disassemble the pickup unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pickup unit. It was already

20、 adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at the pickup lens for a long time.
