Read Speed Control for CD-R Data CD The basic default reading speed for CD-R disc media in this drive is 40X. The Read Speed Control will allow you to select the maximum read speed (52X) for CD-R media, simply by pressing the eject button. Note that this function is only available with a CD-R data disc. To enable 52X CD-R read speed, follow the chart below: Flow Chart Operation User instruction Open the Disc Tray (Push Eject / button) Load CD-R Disc (Put CD-R disc on Tray) Close Disc Tray Initialize 52X READ (Push and hold the eject button for more than 3 seconds) The LED indicator turns on for 3 seconds. The 52X maximum read speed for this CD-R disc has been enabled. The Read Speed Control will allow you to select the 48X maximum read speed for CD-RW Data CD. Ejecting this disc or turning off the PC will disable the 52X maximum read speed function. The drive will default back to the 40X CD-R read speed. CAUTION: The quality of CD-R data disc varies significantly from brand to brand (or brandless), as well as disc condition used over time. A disc that is poorly balanced or that may have cracks in it greatly increases the chance of disc failure or disc shatter when being read back at speeds higher than 40X, possibly causing damage to the drive. Closely inspect discs you plan to use in the drive for any abnormalities or cracks. If you hear strange noise or sounds from the drive during operation, this could be a sign of an unbalanced or damaged disc and it should be removed immediately. LG Electronics does not warranty drive damage caused by faulty or shattered discs. 14
