1. Set the air pressure
Increase the dwell time to its maximum setting by turning the dial labeled “dwell” counterclockwise as far as it will go.
2. Maximize air efficiency
To achieve maximum air efficiency, turn the dwell time down as far as possible until the velocity begins to drop. This is the precise point at which you are providing just enough air through to carry the BB to the end of the barrel. However, if you turn the dwell all the way down, it will set it to zero. If you don’t have a chronograph to do this step, you can also watch the flight of the BB and listen to the sound of the gun firing. When you see a reduction in range or velocity and the muzzle crack becomes muffled, you have turned the dwell down too far and you are no longer providing enough air. Turn the dwell back up just enough to achieve the desired velocity.
3. Adjust rate of fire
The rate of fire (ROF) can be adjusted by turning the dial labeled “ROF” on the FCU. Turn the dial counterclockwise to increase the ROF and clockwise to decrease the ROF. The maximum ROF that can be obtained is determined by the selected operating pressure and dwell settings.
4. Set burst mode
DISCONNECT THE GUN FROM YOUR AIR TANK BEFORE ATTEMPTING TO SET THE BURST MODE TO ENSURE THAT NO ROUNDS ARE ACCIDENTALLY FIRED.
The SMP is capable of programable select fire to allow safe-semi-auto, safe-semi-burst, or safe-semi-semi select fire. To set what mode your gun operates in, do the following.
Now you’re ready to get out and play! To change your settings, be aware of the following:
If you want to change your velocity, start at the beginning of the instructions. With the dwell turned all the way up, set the air pressure to achieve the desired velocity. Then, decrease the dwell until you find the precise point at which velocity begins to drop.
