A common belief is that bullets are destructive and destroy cable boxes, and equipment when received. That is untrue, it is just a signal to set the cable box to its programming, and allows you to see only the channels you pay for. If you are testing a cable box with an RFT then you can call the cable company and have them send a bullet to correct your cable box. Bullets are usually sent out constantly in the background, and are required for some cable boxes to operate. Some cable boxes even shut themselves off if they do not receive a bullet in a set amount of days.
Bullets ONLY apply to brand name original equipment.
Universal cable boxes don't have the capacity to use bullets. We do not carry these devices due to lack of demand. The need to test a cable box is rare, and permanent installations are rarely authorized by cable companies. Please do not ask about these items, we do not sell them. We only provide complete replacements.
