1. GENERAL 

HINTS 

Playing with this NOVAG chess computer is very simple. However we recommend 
reading the instruction before starting to play. 
 
The NOVAG AMETHYST runs on 4 x 1,5V UM 4-type (or AAA) 

alkaline

 

batteries, which allow about 1000 hours of play. Do not use ordinary batteries as 
they will result in irregular performance. To insert the batteries, open the 
BATTERY DOOR on the underside of the unit and place the batteries as indicated 
by the +/- signs.

3. GETTING 

STARTED 

Set up the chess pieces on the board with yourself playing White. The White pieces 
should be placed on the 1st and 2nd rows and the Black pieces on the 7th and 8th 
rows. (see Board Setup). Press the ON/OFF key to turn on your NOVAG chess 
computer and the LCD should display "

", which means you are ready to 

play and it is White's turn. If the display is not showing this, press NEW GAME and 
it should appear. The computer is now waiting for you to make a move, should you 
choose to play the White pieces. If you prefer Black, press ENTER and the 
computer makes a move for White (probably something like "

d2 d4

").
