CHECKING CONFIGURATIONS
You can check your DIP switch configuration by pulling and holding the trigger when you turn the marker on. Hold the
trigger until the LED starts flashing. Red indicates the eye sensitivity setting and yellow the anti bolt stick (ABS) setting (1
flash off and 2 flash on). For example, if your eye sensitivity is 3 and ABS is ON then the LED will flash red three times and
yellow two times.
BATTERY
There is no low battery warning on the DM4. The 9V battery will last for about 40,000 shots, but there are big
differences between different kinds/brands of batteries. Use of high quality alkaline or lithium ion batteries is
recommended for maximum battery life. If you plan not to use your marker for a long period of time (a month) it is
recommend that you remove the battery from the marker. When the battery voltage starts to go too low, you will notice
your velocity starts to decrease and the board can turn off. For tournament use, it is recommended to change the battery
for each tournament. When changing your battery, take special care to ensure the wiring harness is not pinched under
the battery
(see figure 1).
CHANGING THE BATTERY
The battery is housed on the right side of the grip frame. To access the battery remove the three screws holding the right
side grip panel down. Use a 3/32” Allen wrench. Carefully lift the Battery out of the frame, taking care not to damage
the battery lead wires.
When inserting a new battery, make sure the solenoid and eye wires are pushed into the wire passage at the rear of the
frame. This will ensure that the wires are not pinched or cut between the battery and the frame.
NOTE: IF THE MARKER WILL NOT FUNCTION WITH THE EYE ON, THERE IS A GOOD
CHANCE THE BATTERY NEEDS TO BE CHANGED.
Configuration Mode -
The following settings can only be modified in configuration mode. To activate the configuration mode, turn your
marker off and set DIP switch 4 to the on position. Next, turn your marker on. The 3-color LED cycles
through all colors for one second to indicate that you have entered the configuration mode. To cycle
through different settings, pull and release the trigger. Configuration mode has 3 settings that can be changed.
Green - Trigger Sensitivity
Values 1 - 20
(factory default 5)
Trigger sensitivity is the amount of time that the trigger has to be released before next trigger pull is allowed.
In some situations with too low of a value, the marker may begin to shoot full-auto.
Red - Dwell
Values 5 - 30
(factory default 18)
Dwell is the amount of time that the solenoid will be activated. Follow these steps for the best way to set your dwell:
• Remove loader and any paintballs from the DM4 marker.
• With the dwell set at 12, start increasing the value until the marker begins to fire.
• When you reach the setting where the marker begins to fire, get some paint and a loader and go to a chronograph.
• Increase the dwell until you see no increase in the velocity. This is the optimal dwell setting to be used.
Blue - Rate Of Fire (ROF)
Values 5 - 24
(factory default 24bps)
[When Anti Chop Eye (ACE) is deactivated]
The ROF is unlimited by software when the eye is on. The only limiting factor is the loader feeding rate and the marker
pneumatic cycle rate which is by far faster than any loader on the market. You should set this setting to the constant feed rate
of your loader. Setting this higher than your loader is capable of feeding risks chopping a ball.
TO CHANGE THE VALUE OF A SETTING:
1
While in configuration mode, pull the trigger and hold it for more than one second. The LED will flash to indicate the previous setting.
After that, you can set the new value with the trigger.
For example, if you want to change the trigger sensitivity to 7 units:
2
Cycle through menus by pulling and releasing the trigger until the LED lights GREEN
(trigger sensitivity)
.
3
Pull and hold the trigger until the LED starts to flash (factory default for trigger sensitivity setting is 5 units, so the LED will flash 5 times).
4
When the LED stops flashing, pull and release the trigger seven times in a fast pace. The new value is set after you haven't touched the trigger for one second.
The LED will cycle through all colors to indicate that the new value is saved. All other configurations are changed the same way. Just as in part 2 above, change the mode to
RED for "dwell" or BLUE for "ROF when ACE is deactivated" to change the desired configurations.
5
To exit configuration mode, set DIP 4 to the off position.
NOTE: You cannot turn your marker off with the power button when the marker is in configuration mode. You must first set DIP switch 4 to the off position.
NOTE: When you set the values, remember that only trigger sensitivity starts from 1. The "dwell" and "rate of fire" start from 5.
Therefore, to set the dwell at 20, you need to pull the trigger sixteen times, because the first trigger pull will start at 5.
DM4 BOARD
- Settings and Functions (continued).
Normal Mode
Configuration Mode
DM4 BOARD
- Settings and Functions (continued).
• A low battery will not be able to power
both the ACE eye and the trigger switch,
causing ACE eye failure.
• If the battery is low, it may not be able to
power the solenoid correctly. This will
affect the DM4’s velocity, causing it to
become inconsistent and/or low.
