DM4 BOARD
- Settings and Functions.
DM4 BOARD
- Settings and Functions (continued).
When servicing your marker:
• Make sure a barrel sock is fitted
to the DM4.
• Make sure your hopper is removed
from the DM4.
• Make sure there are no paintballs in the
breech of the DM4.
• Always remove the first stage regulator and
relieve all residual gas pressure from the
DM4 before disassembly.
• The DM4 can hold a small residual charge
of gas, typically 2 shots, with the first stage
regulator removed. Always discharge the
marker in a safe direction to relieve this
residual gas pressure.
W A R N I N G
• The DM4 is not water resistant.
Excess moisture can cause damage
to electronic parts.
• Keep the board and all electrical
components clean of dirt, paint,
and moisture.
• To clean the board use canned air. If a
more aggressive cleaning method is needed
lightly scrub the components with a soft,
dry brush. Heavy scrubbing will damage
the board.

TURNING THE DM4 ON AND OFF
To turn on the DM4 press and hold the power button
(see figure 1)
until the LED light turns blue. The blue light indicates
board bootup. After the bootup sequence, the LED will turn either RED (no ball) or GREEN (ball ready to fire). To turn the DM4
off press and hold the power button until the LED turns off.
NOTE: The DM4 automatically switches off after 10 minutes of non-use.
FIRING THE DM4
As soon as the marker is turned on and the LED turns from blue to either red or green, the DM4 is ready to fire. If there is no
ball and the LED is RED, you need to hold the trigger for 1 second to force the DM4 to fire once. If there is paint inside the
breech and the LED is green, just press the trigger to fire the marker.
LED LIGHT INDICATOR
There is a super high intensity LED light mounted on the board behind the DM4 logo on the left side of the grip panels. This
light provides information to the user by the DM4. There are three colors on the LED light. Red, green and blue.
When you turn on the marker in normal operation mode with the power button, the light colors mean the following:
Blue Bootup
sequence.
Red
No ball detected inside the DM4 (eye on)
Green
Ball detected inside the DM4 (eye on)
Blinking Red
Eye function turned off, The DM4 will fire even though there is no ball inside the breech.
Blinking Green
Eye blocked. This means that your eyes are either dirty or there is a bad connection.
The ROF (rate of fire) is automatically reduced to prevent chopping.
If this happens during game play, you can turn the eye off to increase your ROF.
NOTE: The eye is always activated when you turn the marker on.

BOARD SETTINGS AND CONFIGURATION MODE
There are five settings you can alter on the DM4 board with the DIP switches inside the grip frame
(see figure 1)
:
ABS
Anti Bolt Stick.
Eye sensitivity
This setting changes how long the eye waits for the ball to set into the breech.
Trigger sensitivity
This setting adjusts the delay between two trigger pulls.
Dwell
This is the time the solenoid is activated for.
ROF
Rate Of Fire when the eye is deactivated.
Anti Bolt Stick -
When ABS is activated, the dwell is increased after 15 seconds of non-use for the next shot fired.
This helps to prevent bolt-stick, but may result in higher velocity for the first shot.
ABS on
ABS off
(default)
Eye Sensitivity -
The eye sensitivity setting determines the time that is needed to allow the next ball to settle
into the breech. Too sensitive an eye setting may result in chopping and too high a setting limits
the maximum ROF that can be achieved. Optimal sensitivity setting varies between different
paintball brands and the loader used. There are 4 different settings available. These settings can
be achieved using DIP switches 2 and 3.
FASTEST

Setting 1
Setting 2 (default)
Setting 3
Setting 4
DIP 2 - off
DIP 2 - off
DIP 2 - on
DIP 2 - on
DIP 3 - off
DIP 3 - on
DIP 3 - off
DIP 3 - on
The most sensitive and fastest setting is 1; this should only be used with force feed loaders such as a HALO™.
The middle two settings are good for other agitated loaders. Setting 4 is for slower loaders.
