HAL™ Trigger Calibration Before First Use
This airsoft gun is equipped with the HAL™ system, and the trigger must be activated before using the gun. Activation is done as follows:
Setup:
1. Turn the fire selector to the “SAFE” position.
2. Connect the battery to the gun.
3. Wait three (3) seconds until the gun emits a “beep” sound.
4. Pull and hold the trigger for approximately five (5) seconds until the gun emits a “beep” sound. This means that the HAL module activation has been successful.
