SAFETY PRECAUTIONS
Mains Supply
The mains supply required is 240 volts 50 Hz. Aplug is not supplied with the computer
because of the wide variety of wall sockets used in domestic dwellings. You will
therefore need to have fitted to the mains lead a plug suited to the particular sockets in
your home.
We recommend that where possible a13-amp.plug is used, FITTED WITH A3-AMP.
FUSE. Connect the plug as described in the instructions below.
IMPORTANT
The wires in the mains lead are coloured as follows:
BLUE :NEUTRAL
BROWN :LIVE
Connections to atypical 13-amp. plug
These colours might not be the same asthose used to identify the terminals of your
plug, so connect the wires as follows:
BLUE —to the terminal marked N, or coloured black
BROWN —to the terminal marked L, or coloured red
ALWAYS SWITCH OFF YOUR COMPUTER BEFORE
INSERTING OR REMOVING AROM CARTRIDGE

INTRODUCTION
The Toshiba HX-10 Owners Manual has been compiled to enable you to properly set up
the equipment, to familiarise yourself with the connection and operating procedures,
and to begin using the computer as quickly as possible.
The Toshiba HX-10 incorporates many exciting features such as built-in music and
sound effects with aconnection point for stereo or hi-fi, multi-window graphics for
creating ‘perspective’ in graphic images, and, of course, sufficient connections allowing
you to expand the system as your computing requirements grow.
Asample program cassette included with your computer demonstrates the HX-10's
versatility and gives an early opportunity for ‘hands on’ experience.
Before running any program, however, we recommend you follow the procedures
outlined in the Chapters on ‘Setting Up’ and ‘Getting Started’.
NOTICE

2. When using aspecial application program or computation procedure on the
HX-10, it is advisable that the execution sequence, intermediate results, and
final results be checked out carefully.
3. We are not responsible for any financial loss which might result from the use
of the computer.
