Fire Missions using PRF Code
The PRF code is a 4 digit number combination that is in the range of 1111 - 1788 and only digits 1-8 can be used. (for instance 1169 is an invalid code). The code is a target identification mechanism that is to be entered by the observer in VBS3 and in VBS3Fires. The PRF code is to be used with the Laser Designator for Laser Guided Ammunition such as CPHD.
When the observer is in place, choose the Laser Designator from inventory and designate towards the target. It is important to note that the laser designator has to be switched on with the laser.
While in this view using the Laser designator, from the inventory selection menu, select SET PRF code.

A dialog box will open in VBS3 requesting a PRF Code to be entered. Enter the PRF Code which is to be used for the fire mission here and click ENTER.

The system would now take the PRF Code that is to be searched for by CPHD fired ammunitions.
On VBS3Fires, at the third panel, the same PRF Code that was entered in VBS3 is to be entered here for VBS3Fires to interact with the Laser Designator effectively.

Fired CPHD ammunitions start to seek and contact the laser designated target that is aiming over the same PRF Code configuration. The CPHD ammunition will follow the designated laser and impact if the target is achievable. If not it will hit the initially given grid location.
