1.1.1 CD Player and Mini CD Player

   The CD Player and Mini CD Player are two versions of the same Windows

	  (activated by clicking on controls with the mouse)
	* Continuous Play and Shuffle
	* A program feature that lets you assign titles to CD tracks and 
	  arrange titles in a play list
	* A selectable list of all tracks on the play list that appears
	  when you click in the timer window.

1.1.2 Photo CD Viewer

   Photo CD Viewer for Windows enables you to view, manipulate, export, 
   and display Photo CD images. Photo CD Viewer includes the following 

	* Displays Photo CD images in five resolutions, from thumbnail to 
	  full photographic resolution

	  True Color, or grayscale (depending on type of video card)

1.1.3 SCSI Interrogator

   The SCSI Interrogator is a Windows application that displays 
   information about the SCSI devices on your system. When you double-
   click on a device icon you can view information about its supported 
   features, manufacturer, model number, storage capacity, etc.

1.2 DOS application

   When installed under DOS, the following utility is installed on  
   your PC.

	DOS CD Player

1.2.1 DOS CD Player

   DOS CD Player requires a VGA (or higher) graphics controller and either
   a color or monochrome display.

   To start DOS CD Player, change to the EZ-SCSI directory (usually 
   C:\SONYSC), type the following:

	C:\SONYSC>cdplayer <Enter>

   You select functions either by clicking the mouse on a button or by 
   pressing the Hot Key letter. For example, you press [P] or [p] to play 
   and [Q] or [q] to quit the program. The Hot Key letter appears in white
   on each button.

   Command Line Options
   By default, the DOS CD Player plays CDs in the CD-ROM drive with the 
   lowest drive letter. If you have multiple CD-ROM drives, and the one 
   with the lowest drive letter is not the one you want to use, you can 
   direct it to another drive with a command line option.
   For example, if you have two CD-ROM drives assigned to drive letter E 
   and F, and you want to play a disc in drive F, start the program with
   this command line:

	cdplayer /f:

   Be sure to include a colon after the drive letter.

   program while the disc continues playing. If you restart the DOS CD 
   Player before the disc is finished, the screen displays the current 
   track and playing time.

2. Windows 95 notes

2.1 Connecting the PRD-250 to your PC

   The PRD-250 does not have to be connected to your PC when booting. You 
   can connect it after Windows 95 has started. 

2.2 Plug and Play

   You can insert and remove the PRD-250 PC card while Windows 95 is 
   running. Please note, however, that you have to notify Windows 95 before
   removing the card from your PC. To do so, follow the steps below:

	a) Click the PC Card icon in the Task Bar.
	b) Click "Stop Adaptec APA-1460 SCSI Host Adapter."
	c) When message appears, click OK and remove the card.

   If you press the STOP button on the PRD-250 when the drive is connected
   to your PC, the drive will not be recognized by Windows 95 until the 
   PC card is inserted again. To use the drive again, follow the above 
   steps to remove the card, press the PLAY button to supply power and 
   insert the card again.

3. Windows 3.1/DOS notes

3.1 Connecting the PRD-250 to your PC

   BEFORE YOU BOOT YOUR PC. If the PRD 250 is not present when booting your
   PC, the CD-ROM device driver will not be loaded. 

3.2 Multiple APA-1460 PC card 
   If two APA-1460 SCSI card are inserted in one system, the second host
   adapter will not be seen by ASPI manager. However, the first APA-1460
   still operates normally.

3.3 New Media WAVjammer

   If you use the PRD-250 alone with a New Media WAVjammer PC card, you
   need to add /IRQ = n to the command line of the client driver
   (NMCMSSND.SYS). The 'n' should be an IRQ number other than the one that
   APA-1460 is using.

3.4 Suspend/Resume function

   Many notebook PCs have suspend/resume function. If you have a problem 
   with this function when the PRD-250 PC card is inserted, remove the 
   card before suspension, or disable the function.
