10 and then press the RETURN key. Next insert the WELCOME cassette into your recorder. If your cassette recorder has a tone control then set it to maximum ‘treble’ and leave it there. Now start the cassette recorder playing by pressing the PLAY button on the recorder. Then adjust the cassette recorder volume control slowly, until you get the message: Your volume control is now properly set. Please wait while the first program is loaded on the screen. This will give the minimum volume level. You should then increase the setting a little more. If you need to, you can rewind the tape at any time.

If no message appears rewind the tape and play it again, increasing the volume control setting in larger steps, or check the cassette leads are correctly plugged in. The system is very reliable, so if you have problems it may be that your tape recorder is at fault or that you have a fault in the computer. You are advised to contact your dealer. Note: Each computer program is recorded on the tape as a kind of screeching noise. It’s not meant to be listened to, but some cassette recorders have the annoying habit of playing the tape through the loudspeaker while the tape is loading into the computer. Everything depends on what plugs and sockets are being used.

It is possible to stop this on most recorders by inserting a small (3.5mm) jack plug into the socket on the recorder marked EAR. You could insert the ear piece supplied with the recorder if that is more convenient. On other recorders you may have to insert a DIN loudspeaker plug, with no wire connections, into the socket marked LS to turn off the noise. Don’t try turning the volume control down because then the computer will not be able to ‘hear’ the tape either. The important thing to do is to try to disable the loudspeaker as described above. Make a note of the volume setting on your cassette recorder and always use that setting when playing back the WELCOME cassette.

You may need to use a different setting with other tapes that you have purchased or recorded yourself. On the WELCOME cassette the volume control setting is repeated many times at the beginning of the tape. With practice it is possible to save time by running the tape forward by about two minutes (once the volume control is set) and then begin playing the tape from this point, having first entered the command CHAIN "WELCOME" RETURN When the first WELCOME program has loaded into the computer it will clear the screen and give you instructions. The WELCOME pack includes a booklet which describes not only how to get the programs running but also what each of the programs does.
