SAFETY NOTICE

SAFETY/1

Safety and Regulatory Notices

Read the separate Power Connection Guide before using the computer for the

first time.

The computer uses a safety ground and must be earthed. The system unit

AC power cord is its ‘disconnect device’. Ensure that the system unit is

positioned close to the AC power outlet and that the plug is easily

accessible. The power cord packed with the computer complies with the

safety standards applicable in the country in which it is first sold. Use only

this power cord. Do not substitute a power cord from any other equipment.

It is imperative that the system unit is set to the correct voltage range before

use. If not, the machine may be irreparably damaged.

To prevent fire and electric shock, do not expose any part of the computer

to rain or moisture.

When positioning the system unit, monitor and keyboard, take into account

any local or national regulations relating to ergonomic requirements.

Microphone, headphone and speaker cables should be less than 2 metres

long.

Replace a discharged configuration (CMOS) battery with one of the same

type. Dispose of the battery in accordance with the manufacturer's

recommended instructions. Do not attempt to recharge, disassemble or

incinerate. Keep away from children.

Any CD-ROM drive fitted in this system is

classified as a CLASS 1 LASER PRODUCT

according to IEC825 Radiation Safety of Laser

Products (Equipment Classification: Requirements

and User's Guide).. The CLASS 1 LASER

PRODUCT label is located on the under side

of the system unit.

Use the CD-ROM drive only as described in

this manual. Failure to do so may result in

exposure to hazardous radiation.

Refer to the labels on the computer to establish

which of the following applies.

SAFETY NOTICE

SAFETY/2

E.E.C.

This equipment complies with the relevant clauses of following European directives:

89/836/EEC and 73/23/EEC,and is able to bear the CE mark.

U.S.A

FCC Class A

Warning - this equipment has been tested and found to comply with the limits for a Class A computing

device, pursuant to Subpart J of Part 15 of FCC rules. Only peripherals (computer input/output devices,

terminals, printer, etc.) certified to comply with the Class A limits may be attached to this computer.

Operation of this equipment in a residential area may cause unacceptable interference to radio and television

reception requiring the operator to take whatever steps are necessary to correct the interference.

FCC Class B

Warning - this equipment has been certified to comply with the limits for a Class B computing device,

pursuant to Subpart J of Part 15 of FCC rules. Only peripherals (computer input/output devices, terminals,

printer, etc.) certified to comply with the Class B limits may be attached to this computer. Operation with

non-certified peripherals is likely to result in interference with radio and TV reception.

Radio and television interference

The computer described in this manual generates and uses radio frequency energy for its operation. If it is not

installed and used properly, in strict accordance with the manual, it may cause interference with radio and

television reception.

The computer has been tested and found to comply with the RF emission limits for an FCC Class B

computing device which is intended to provide reasonable protection against such interference in a

residential installation. However, there is no guarantee that interference will not occur in a particular

installation.

If this equipment does cause interference with radio or television reception, which can be determined by

turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of

the following measures:

•Move the computer away from the receiver being interfered with.

•Turn the computer with respect to the receiver.

•Turn the receiver with respect to the computer.

•Plug the computer into an outlet that is on a different branch circuit from the receiver.

•Disconnect and remove any I/O cables that are not being used.

•Unplug and remove any expansion cards that are not being used. Replace the relevant blanking

plates.

•Make sure that the computer is plugged into a grounded outlet

If you need additional help, consult your supplier. You may find the following booklet helpful, How to

Identify and Resolve Radio-TV Interference Problems. This booklet is available from the US Government

Printing Office: Washington DC 20402 - Stock No. 004-000-000345-4.

PREFACE

There are many variants within the Apricot VS and LS range. The

basic difference being a Soundblaster 16 bit audio system, integrated

into the computer’s motherboard.

Some systems also may be supplied for the networking environment

and therefore may not have a hard disk fitted. These systems would

probably have a network card installed in an available slot.

Similarly, some systems may be supplied with Windows ®95 instead

of DOS and Windows ®as their operating system. The appropriate

guide will be supplied for the software.

This handbook is intended to give advice and guidance on the use of

your computer and include details on some of the optional drives

and upgrades that you may have chosen to be fitted into it.

Many of these will have been fitted prior to supply, during

manufacture at the factory. Others may be installed by your supplier

or Apricot dealer.

1 THE BEGINNING. . .

You should read this chapter even if you do not read any other. It

provides important basic information to help you in using your

computer. It is the minimum you need to know in order to start

work straight away.

Note particularly the information given in the section

‘Energy Saving Features’.

Connections

Individual details of the rear port connections are shown in the

appendix B ‘System Motherboard’, but an overall view is given here.

1 Mains in socket 2 Power out to monitor 3 Optional case lock

4 System security loop 5 Rear audio panel *a 6 Keyboard port

7 PS/2 mouse port 8 Serial port (COM1) 9 Serial port (COM2)

10 Parallel/printer port 11 Monitor connection

*a If fitted. See chapter ‘Multimedia’ for details on connections.

The optional Security case-lock (3), can help prevent unauthorised removal

of the cover, while the security loop, (4) above, can be used for an alarmed

loop cable or a padlocking mechanism. This will help deter theft of the

system, or removal of its cover if the case-lock, (3), is not fitted.

Turning on and booting the computer

Turning the power on

To turn on the computer, press the lower POWER button. The green

POWER ON light should come on to show that the system unit is

powered. Remember that the monitor has its own power control (see

the monitor’s User’s Guide for details) and that it may take a few

moments to warm up. Do not touch the purple button yet.

If nothing happens when the POWER button is pressed, check that

the system unit and monitor power cords are securely connected and

that the AC power supply is switched on. See also the chapter on

‘Troubleshooting’.

Power-on self-test

Whenever the computer is turned on, the ‘power-on self test’ (POST)

routine checks the actual set-up of the computer against that

recorded in its internal configuration memory. During this time,

various messages are displayed. Further information on the

computer’s Basic In/Out System (BIOS) and its setting up can be

found in Appendix C, ‘System BIOS and set-up’.

The boot sequence

Provided that POST succeeds without any serious errors, the

computer attempts to find its operating system to start it going, that

is, it attempts to boot. By default, the computer will first look for a

system diskette, then for a bootable hard disk partition or area.

System diskette

A system diskette is a diskette bearing at least the rudiments of an

operating system. If the computer finds such a diskette in the

diskette drive, it boots from it. If it finds a non-system diskette, the

computer will ask you to replace it.

Bootable Hard disk

Most computers with a hard disk containing pre-installed software

arrive set up with a single ‘partition’. The operating system already

in place or pre-installed on this, the C: drive, and it is usually made

‘active’, i.e. the bootable hard disk.
