Scrabble + Upcount (Option 21); Hourglass (Option 22); Internet Chess (Option 23); Batteries - FIDE DGT XL Manual De Usuario

When playing with traditional clocks was the method that was most commonly used, an
official who would be in control of the time using a stopwatch would always accompany
the players.
The player gets an extra 5 or 10 minutes of extra thinking time to complete a
predetermined number of moves, usually 10 or 15, after the standard thinking time has
been used up.
When the Byo-yomi method is active it is possible to reload the Byo-yomi time
for the player whose time is currently counting down by pressing and holding
the BACK button
in the display a player must indicate their turn is over.

10. Scrabble + Upcount (Option 21)
In Scrabble, games have to be finished, even if a player exceeds the available thinking
time. The more time a player uses after exceeding the available thinking time, the bigger
the number of points that will be subtracted.
You can use Upcount as an independent method by choosing manual settings
(option 00). This way, the display will show 0 seconds when starting the game.

11. Hourglass (Option 22)

The thinking time for the player to move decreases, while simultaneously the opponent's
thinking time increases.
This method offers an exciting alternative to the traditional 'quickie'.

12. Internet Chess (option 23)

In combination with a DGT Electronic Chess Board, the DGT XL can be used for playing
games on Internet Chess servers, or as a computer controlled clock for playing against
chess programs. When option 23 is activated, the clock accepts game timing instructions
or messages from the server. For these functions, the board driver version 1.10 or later
(dgtebdll.dll) must be used. This driver and additional information is available on

Operation

1. Batteries

The DGT XL requires 2 AA (penlight) batteries. We recommend alkaline batteries.
To insert the batteries, remove the cover from the battery compartment on the bottom
of the timer by clicking on it.
NOTE: If you do not plan to use your timer for a long period, we recommend that you
remove its batteries.
If 'BAT' (Fig. 2G) appears on the timer display, the batteries are nearly discharged and
should be replaced as soon as possible. When this message first appears, the batteries
still contain enough energy to allow the current game to be completed.
See the below paragraph 9 how to check the battery condition.
