that square, please lift it up briefly).  The current level setting will be displayed on the LCD and 
the LEDs on the corresponding square will light up. If you wish to change the level setting tap the 
square corresponding to the level you wish to set (please see LEVEL CHART at the beginning of 
this chapter) and the LCD will show the level number. For example if you wish to set level At 4, 
enter the SET LEVEL mode and then tap the square B4. On the LCD display you will see

unit. 

Note

: You can always check or change the skill level during a game, however not whilst the 

computer is calculating! Changing level resets the clocks. If you switch the computer off 
to continue your game at a later time or if you start a new game, the previously set skill 
level will be retained.

SQUARE B8 : RANDOM

Every time you switch the computer on, the move with the highest rating is chosen automatically, 
based on the depth of the search which is determined by the skill level. This is always the case 
after the opening is finished. 
 
If you select the RANDOM function when in the MENU mode (see “USING THE MENU 
FUNCTION” above) you can choose various levels of randomness.  To do so, tap on square B8 
and any of the following random levels will be displayed in the LCD each time you tap on the 
square: 

rAnd /  r And - /  rAnd = /  rAnd 

(Level "

rAnd

" is the least random). The computer 

will select a move at random from a list of possible moves which are similar in their evaluation. 
To save and exit, press the MENU button on the right hand side of the unit.

SQUARE C8 : EASY

The chess computer always uses the opponent's time to compute its best response since it has 
predicted your move and completed its assessment of your move. To disable this advantage please 
enter the EASY function (see “USING THE MENU FUNCTION” above). When this mode is 
activated you will see the message "

EASY 

" on the LCD and if turned off you will see "

EASY

". 

To turn it on or off, please toggle square C8 and it will change from “

” with 

each tap, then press the MENU button on the right hand side of the unit to save and exit.
