6. GETTING STARTED
Connect VK2000 firmly to a free serial port of the PC. Double-click on the program icon to start the
control software which will come up with the screen pictured below for the selection of the serial port.
By default, COM1 is selected. Any valid selection you make will be stored in an initialisation file and
be available at next start up. Before going further, please make sure that the serial cable is properly
connected to both VK2000 and the host. Then engage power to VK2000 and push the Reset button
briefly before you click on the START button.
NOTICE
When using a laptop or notebook, noise may interfere from theAC adapter. In such an event please run on
the battery.
The recording devices, ML2500, MSM9841 and MSM9888L have no pre-recorded samples associated
with them. Please record first before you click on a playback button.
7. THE SPEECH LSI PANEL
The LSI panel is the working screen. The control software is so designed as to provide a panel on
which each LSI can be selected and activated simply by a mouse click. Please refer to the following pages
for more information.
Commonly used by all LSI modes are the optical symbols for REC, PLAY and PAUSE, which come
on and go off in accordance with a current selected mode.
RECORDING
PLAYING BACK
REC/PLAY PAUSED
