Chapter 1
Customer Information
This chapter summarizes the Information the customer receives. This indudes basic setup
instructions and Software operations. The Amiga CD32 System comes with the items illustrated
in Figure 1-1.
Figure 1-1. Amiga CD 2 System

1-2 Connecting a Television/Monitor
Connecting a Television/Monitor
The easiest way to connect the Amiga CD32 System to a television/monitor is to use the RF
modulator that provides all the video and audio connections necessary. For a PAL System: Use
the provided RF modulator cable. For a NTSC System use the provided RF switch box to
connect a television/monitor with a VHF cable (F-type) connector and 75Q antenna, cable or
VCR cable. The NTSC System requires a 300/75Q Converter for an antenna or rabbit ears with
twin lead wire and a 75/300Q Converter for VHF screw type connectors.
S-video and composite video are options, but require the customer to purchase additional
spedalized cables. The customer is referred to his TV documents in order to determine whether
his set is S-video or composite video compatible.
The Stereo audio cables allow the customer to connect to TV stereo, powered Speakers, or
Standard stereo output.
See Figure 1-2 for the location of the side and rear panel features.
Figura 1-2. Slde and Rear Panels

Connecting a Television/Monitor 1-
Table 1-1 lists each socket on the System unit side and rear panels and summarizes the
Information provided to the customer.
Table 1-1. Side and Rear Panel Connectors
Connector Description
Game Controller
Connector Plug the game Controller into socket 1. To use a second game Controller, joystick
or mouse, plug it into socket 2. Donl plug or unplug a Controller while the power is
on.
Auxiliary Connector To use keyboard or another device, plug it into the socket marked AUX.
RF Connector Plug the RF modulator cable into the jack and the other end into the
television monitor.
For a PAL System:
Set the switch to the left (5.5 mHz) for the United Kingdom and to the right (6.0
mHz) for all other countries.
If the television monitor picture is not clear, use a small flat-bladed screwdriver to
turn the screw until the picture is in Sharp focus.
For a NTSC System:
Set the switch to left for channel 3 and or the right for channel 4, whichever is not
used in your geographical area.
For both Systems use the television monitor volume control to adjust the sound.
S-video Connector To use S-video, the customer must buy an S-video cable with a 4-pin mini-DIN
connector at each end. Plug one end of the cable into the socket under the Symbol
and the other into the television monitor.
Composite Video
Connector To use composite Video, the customer must buy a composite video cable with an
RCA plug at each end. Plug one end of the cable into the yellow socket and the
other into the television monitor.
Right and Left Audio If the customer has a Stereo television monitor, he can use the Stereo audio cables
Connectors shipped with the System. Plug the white cable into the white socket and the other
cable into the red socket. Connect the other end to the television monitor.
If the customer wants to connect a television monitor with mono sound, he should
plug the white cable into the white socket under the Symbol. Do not connect the
other cable. Plug the white cable on the other end into the television monitor.
Plug in the power supply and turn on the System only after securely connecting these options.
In the United Kingdom manual, the customer is told to have a certified electrician attach the
correct plug to the cable.
The control panel in the front of the machine contains the reset button, power and disk activitv
lights, headset jack and headset volume control.

1-4 Using the Amiga CD 2 Software
The Game Controller
The System comes with a customized game Controller that has four play buttons, a pause/start
bar, two general feature bars and an omni-directional movement button. The Controller is used
for controlling game play, making audio selections and defining System set-up options..
Using the Amiga CD 2 Software
Once the System has been tumed on, you can change CDs by just lifting the lid and the disc
stops spinning. The System Starts again when you dose the lid.
• Ifyou put an Amiga CD32 game in the drive the logo screen appears for a few seconds while
the game loads. Then the game Starts.
• Ifyou put an audio CD in the drive you’ll see the audio control display.
• If there is no CD in the drive you'll see the Amiga CD32 logo screen.
Play Ing Audio CDs
The user can play an audio CD in one of two ways: from the Controller or from the audio display.
The easiest way is to press the appropriate button on the Controller. The function Symbols
associated with the buttons are identical to those on the display. The other way is to highlight
the appropriate box on the display and press the red button to select it. Use the black
directional button to move the highlight around the display.
Selecting a Language
From the logo screen press the blue button to see the language selection screen. Choose a
preferred language for game playing on this screen. This is a one time selection.
Locking Game Information
From the logo screen press the red button to see the gamelock screen. The Amiga CD32 can save
100 memory units worth of game information. This screen allows the user to protect old game
information from being aeleted or replaced by other game information by "locking" it.
