Example Dwell Setting: To set a dwell value of 8ms,
rst press the lower programming button repeatedly
until it chirps rapidly indicating that the bottom value
of 3ms has been reached. Then, press the upper
programming button 20 times (20 x 0.25ms = 5ms.)

The dwell and rate of re adjustments are made using the Shocker NXT’s two programming but-
tons. Removing the two grip screws on the left side of the Shocker NXT’s grip frame and folding
back the grip provides access to the programming buttons. The two buttons are small, gray and
rectangular in shape. They are mounted on the front side of the circuit board facing the left edge
for easy access. Notches in the board help to identify the buttons and make them easier to press.
The upper button is located near the top of the board, just below the wiring harness plug, and the
lower button is located near the bottom of the board, just above the round black speaker.
The dwell setting determines how long the Shocker NXT holds open its solenoid valve, which ulti-
mately affects how much gas is released to re each shot. It is important to balance the dwell and
the operating pressure (the setting of the vertical regulator). Too high of a dwell with a low operat-
ing pressure will cause poor gas efciency. Too low of a dwell will leave the Shocker NXT unable to
cycle through a full ring sequence. Dwell setting changes should not be used to adjust velocity.
The dwell value can be adjusted between 3 milliseconds (1ms = 0.001 seconds) and 18ms in
20.5ms increments. To adjust the dwell, make sure the Shocker NXT is already turned on and press
the upper dwell button once for every .25ms increase desired. The circuit board will chirp at each
adjustment to provide feedback that the dwell value has changed. To lower the dwell value press
the lower programming button once for every .25ms of dwell reduction. When either the lower or
upper dwell limits are reached, the circuit board will chirp rapidly in a lower tone. To set an exact
dwell value, cycle to either the upper or lower limit, and then step the dwell value the desired num-
ber of times.
To optimize your dwell setting, wear proper paintball protective goggles and gas up your Shocker
NXT with a barrel blocker in place and with no paint or hopper. Turn on the Shocker NXT and press
the power button once to de-activate Vision mode. Decrease the dwell time until the Shocker NXT
can no longer complete a full ring cycle (bolt does not close all the way) each time you pull the
trigger. Increase the dwell value one button press at a time, test ring after each change until you
hear the Shocker NXT re a full volume shot. Increase the dwell by an additional 10 to 15 button
presses to reach the setting for best gas efciency.
