WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during servicing of the unit. 1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from the laser pick-up unit at all times. Do not stare at the laser beam at any time. 2) Do not attempt readjustment, disassembly or repair of the laser pick-up, unless noted elsewhere in this manual. 3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Cover (MD)
Laser Emitting conditions:

1) When the Cover (MD) is removed, and the POWER SW is turned to the "ON" position, the laser component will emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.), the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period! If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laser emissions. 2) The laser power level can be adjusted with the VR on the pickup PWB, however, this level has been set by the factory prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device.

Possible cause and check content Perform *1. Perform *2. Perform *1.
*1: Poor soldering of the line at Pin 100 of IC1401. Check the line of Pin 93 of IC1401 for short and poor soldering. (Check all the way to the SW P.C.B.) *2: Check the line of Pin 3 of IC1401 for poor soldering and short with other patterns. Check the pick-up laser for breakage.
q Confirmation of pick-up laser power Recording and reproduction can be checked by using the laser power meter. However it should be used for checking only because there is variation in its measurement. When the measured value is excessively deviated from the reference value, replace the pick-up. Reference value (measured at room temperature of 25 °C) During reproduction (ppw) : 0.72 ± 0.1 mW During recording : 5.5 ± 0.5 mW Note : Be very careful when using the laser power meter. The laser beam would cause damage to your eye if exposed to it directly.
q TEMP (temperature standard) setting (Make this setting quickly when the room temperature is within the range of 21 °C to 29 °C and the P.C.B. is cold.) (1) Set to the TEMP setting mode menu. [ TEMP x x ] : Temperature measured value x x : Temperature setting value (2) Make temperature correction based on the ambient temperature and according to the following table.
Ambient temperature + 21.0 °C ~ + 23.2 °C + 23.3 °C ~ + 26.8 °C + 26.9 °C ~ + 30.7 °C Correction value 1H ± 0H + 1H
Example : When the temperature measured value is 7AH and the ambient temperature is 22 °C:
MDX-596
7AH (measured value) - 01H (correction value) = 79H (setting value) * If the temperature measured value deflects between two values, use the smaller value (If 7AH and 79H in the above example, use 79H.)
(3) Using the jog dial, match the value obtained in Step (2) with the temperature setting value. Example : When the temperature measured value is 7AH and the ambient temperature is 22 °C:

s TROUBLESHOOTING
When MD fails to operate When the objective lens of the optical pickup becomes dirty, MD may fail to operate. Clean the objective lens first and check MD for reproduction function. If it still fails to operate, check according to the following flow charts. Contaminant on the pickup lens such as dust or other foreign matter may cause the pickup to skip or the TOC (content of the selection) not to be displayed. Check if the lens is clean before making adjustments. If the lens is dirty, clean it as follows. q Turn off the power. Dampen the lens cleaning paper with a small amount of isopropyl alcohol and wipe the lens with it, using care not to cause any damage to the lens. Be sure not to touch the lens with your hand directly.
