5. Full setup and clock modes
In sections 3 and 4 of this manual a short explanation is given of how to quickly set up the
clock. In this chapter we will go over the functions and modes of the clock in more detail.
Selection mode
When you turn on the clock it starts in “Selection mode”. In this mode you can navigate
through all options using the plus and minus buttons. For each possible option the display will
show the starting time, the total number of periods, the default freeze, sound or forced move
counter settings. And the two bars indicating which side is white.
If freeze is activated, the clock will not be able to count down on either side if one side has
reached 0:00. Freeze is on by default for all Bonus and Delay options but can be turned off.
Figure 2. Selection mode

4DGT2500
Manual
In this mode you can switch the lever freely, but not change any other settings.
Pressing the left arrow button will show the settings details. More information on setting the
chess clock is given under the heading “Setting details” of this section.
When you have found the timing option you wish to use, press the play/pause or right arrow
button to select it.
If you want to check if the chosen time control/ option is correct, you can also press the left
arrow to show the setting details.
When all settings are correct, press the play/pause button to start the clock.
Time running mode
When the clock has been started, it will start counting down on the side where the lever is up.
When a player has finished their turn, they must push the lever down. When this happens, the
other side has the lever up and their clock starts counting down. This will continue until either
side has reached zero.
Wait for start
After selecting an option, the clock enters “Wait for start” mode. This is the “Pause” before
the start of a match. Now some final adjustments can still be made:
The freeze function can be turned on or off by holding the right arrow button.
The sound function can be turned on or off by holding the minus button.
The “Forced move counter” can be turned on or off by holding the left arrow
button.
The position of the lever can still be changed to indicate the correct starting
side/ white side.
When the clock is running, pressing buttons has no effect except when the plus button is
pressed and the move counter screen is shown. This can be done with or without “Forced
move counter” active.
When the time is running the option and period numbers will be hidden. If the sound, freeze
and/or “Forced move counter” are activated, the corresponding symbol will remain visible.
Figure 3. Time Running mode

DGT2500 Manual
Show move counter
During certain modes the move counter can be shown using the plus button. When holding
the plus button, the screen will show a “W” and “B” to indicate the “White” and “Black” side.
The digits next to the “W” and “B” show the number of times the lever has been switched.
Which, when the clock has been properly used, should correspond to the number of moves
completed on the board.
Pause
You can pause and start the clock by pressing the play/pause button. This will pause the
countdown for both sides, the play/pause symbol will be shown, and the option number
and period number will be visible. During pause you can turn the settings for freeze, sound
and “Forced move counter” on or off. But you may not change the lever position. If the lever
position is changed during pause, it must be returned to it’s original position from before the
clock was paused. Otherwise, the clock will go in to “Arbiter mode” as a safety precaution.
Flag-fall
A Flag-fall occurs if a player has used all their available time. To indicate the Flag-fall, two
blinking bars are shown above the numbers 0:00. If the clock is used with the freeze function
not active, the other side is still able count down if the lever is up on that side. If freeze is active,
the time cannot count down for either side after 0:00 is reached. Even if the lever position is
switched.
Note that the flag bars are also shown when a period transition occurs. At that moment the
flag bars are displayed (not blinking) for 5 minutes.
Setting details
It is possible to check the current settings of the clock during “Option select, Wait for start
and Pause”. By pressing the left arrow button, the clock will first show the time control
category. For example, “Fischer” for Fischer bonus time controls. By pressing the right arrow,
you can go to the next screen and view the starting time of the first period. When you press
the right arrow again you can see the bonus time for the first period. This action can be
repeated until you have seen the starting time and increment for each period.
Return to the previous clock mode by pressing the left button again, pressing the play/pause
button or by pressing the right button until all information screens have passed.

Manual
For each of the timing methods a separate manual setting is available on the clock. In the
manual setting you can set a custom time per period. Option specific time settings such as
bonus, delay or Byo-Yomi periods can also be customized.
6. Manual settings
When you enter the manual setting for the first time, you will see a display as shown above.
The number in the corner of the display indicates that you are editing the starting time for the
first period.
The bars are blinking above and below the digit that is currently selected. By using the plus
and minus buttons you can edit the digit value. Pressing the arrow buttons will move you
to the next or previous digit. Changes made to the left side of the clock are automatically
applied to the right side. If you wish to make an asymmetric setting, first edit the left side.
Then change the time on the right side. At the last digit of the screen, pressing the right arrow
button will move you to the next screen.
After setting the starting time for the first period, the second screen depends on the chosen
manual setting type. In the picture above the second screen for the “Fischer bonus” manual
setting is shown. Editing the values is done in the same manner as in the previous screen.
After setting the bonus, delay, or other option specific setting, you will enter the moves
screen. In this screen the number of moves per period can be set. If you do not wish to use
the “Forced move counter” you can leave the number on zero. If set to a specific number,
the clock will transition to the next period after the set number of moves is completed.
Note that the bonus or delay must be set for each period. If you wish to use a bonus starting
from move 1, the bonus must be set for period 1 and again for any periods that may follow.
If you wish to use a bonus only during a specific period, then you must set the bonus only in
that specific period.

Figure 6. Bonus selection in manual mode

DGT2500 Manual
To set the bonus from a certain number of moves, the forced move counter must be used. For
example, if you want to set a 30 second bonus starting from move 61. Then set the move count
to 60 in the period before the period that has bonus time. Note that if you have more than two
periods, a move count must be set for all preceding periods.
During the manual setting, you can quickly accept all settings by pressing the play/pause
button. This will skip any further screens and corresponding period settings.
In certain cases you may want to make a correction to the time or the move counter after a
game has already started. This can be done using Arbiter mode. The set-up sequence is the
same as the manual set-up. To enter Arbiter mode, press and hold the Play/Pause button for 3
seconds when the clock is paused.
Quick time penalty
It is also possible to quickly add 1 minute to either side of the clock without going into Arbiter
mode. When the clock is paused, press and hold the right arrow button.
Then press the minus button to add 1 minute to the left side.
Or press plus button to add 1 minute to the right side.
8. Arbiter mode
7. Period transition
When a timing option has multiple periods, the transition from one period to the next occurs
when the time reaches 0:00 in the first period. The time of the second period is applied and for
5 minutes the “flag” bars will be shown to indicate a period transition.
Period transition by move count
It is also possible to set the clock, so that the period transition occurs when a certain number
of moves have been made (or to be precise, when the lever has been switched a certain
number of times). This function is called “Forced move counter”. If this function is active, the
time of the next period is added automatically to the current time when the move counter
reaches the set number of moves. For the default options, the move count has been pre-set
based on standard FIDE timing systems. If you wish to set a different number of moves, use a
manual setting instead.
If you wish to play with the period transition based on the move counter. First select the
option you wish to play. Then before starting the game, press and hold the left arrow button.
When the # symbol appears on the display, the “Forced move counter” is activated.

9. Glossary
Time
In Time mode the clock counts down the time on the side where the lever is up.
Fischer bonus
In Fischer bonus settings players receive an additional amount of time for each move. A bonus
time is added before each move from the start of the game. Playing with increments (bonus)
has become the standard in chess.
Delay
In Delay settings the players are given a certain amount of free time at the start of each turn
before their main thinking time starts counting down. This Delay time is added to the main
thinking time in the display so that the total time available to each player is always visible. At
the start of a player’s turn, the clock starts to count down and if the player moves within the
delay time, the time in the display will return to what it was before the start of the turn.
US Delay
In US Delay settings the clock has a separate timer that starts counting down before each
turn. After the separate timer has finished counting down, the main time will start to count
down.
Byo-Yomi
In Japanese Byo-Yomi settings players transition to the Byo-Yomi period when their main
time runs out. The player receives a number of Byo-Yomi periods with a set amount of time
per period. If the player completes their move within the time of that period, the period time
is reset. However, if they exceed the time of that period, the time does not reset, and the next
period starts counting down. Each time you exceed a period’s time, the number of remaining
periods is reduced by one. When the time in the last Byo-Yomi period is used, the player has
lost on time and the flag will be shown.
Canadian byo-yomi
In Canadian Byo-Yomi, when main time runs out, the player enters a second period to
complete an agreed number of moves in a certain time. When the agreed number of moves is
completed, the player’s clock can be reloaded with the Byo-Yomi time by pressing the minus
button for two seconds.
Hourglass
In Hourglass options players start with the same amount of time on the clock but when one
player’s clock is counting down, the other player’s clock is counting up.
Gong
In Gong options players receive the same fixed amount of time for each move. They must
make their move when the clock signals the end of their turn. The lever is not used in this
option.
Scrabble™
In Scrabble™ options, when zero is reached, the clock will start counting up.
Move timer
In Move timer settings, the clock will countdown a set time and a player must complete their
move before the timer reaches 0:00. The time is then reset for their next move.
