How to squeeze a trigger: Step one....

All the KM2 circuit boards or board modifications use the same general method of programming the different fire modes.
These general instructions cover the Gabriel, the Glacier, the Gale Force, the Gladiator
and the forthcoming Genesis boards.

If you simply turn the gun on, it will automatically default to standard semiautomatic mode. If the board has the capability of programmable timing or dwell adjustments, the previously-set adjustments are "remembered".

To activate one of the Gabriel-type fire modes, with the gun off, hold the trigger back. Then turn the gun on, and release the trigger. You're now in "program mode".

Then, you can click the trigger once to select a fire mode, or click it twice to select "burst fire".

If you clicked it once, you now have four options:

• One click- Standard Semiautomatic.

• Two clicks- "Turbo" mode, or three shots for every two pulls.

• Three clicks- "Autoresponse"- it fires once on the pull of the trigger, then again on the release.

• Four clicks- Standard fully-automatic.

If you clicked it twice (for a "burst" mode) you can now enter the number of shots for the burst. Click it twice for a two-shot burst, three times for a three-shot burst, five times, ten, forty, or whatever, on up to 200 shots, if you want. (But that's pretty much the same thing as "full auto", so hey... )
The "burst" mode only continues as long as the trigger is held back. If you have it set for an eight-shot burst, and you release the trigger after only four shots have been fired, the gun stops immediately, and resets for another full burst when the trigger is pulled again.

All Boards also incorporate a "tournament lock", which locks the system in either semiauto only, or, if the event permits, it can be locked in "Turbo-9": turbo mode, limited to 8.75 shots per second.

Some boards, such as the Shocker, have other trigger-programmable modes as options.
In the Glacier, the first-click fire mode is called "Sniper" mode- this fires the gun on the pull of the trigger, but the bolt does not reset until you release it. This mode is especially handy when "timing" the Shocker.
Also for the Shocker is the optional AT, or Advanced Timing, system. This option allows the user to program the fire pulse, the bolt pulse, the bolt standoff (the interval between the gun firing and the bolt cycling) as well as the overall ROF.
Using the AT system, the user can fine-tune their marker's operation to millisecond precision, no matter whether they have a vertical feed, standard side feed, powerfeed or an air-assist.

Any board that allows external timing or dwell changes also incorporates a "tourney lock" for that option as well, since some timing changes can and do have an effect on velocity.
