FAQ

• A: Hook your antenna to the BNC connector on the left side of the FX-2. We recommend using RG174 for a feed line up to 25 feet in length.
• Q: What type of key can I use with the FX-2?
• A: You can use either a straight key or a paddle key. The paddle key requires a 1/8 stereo plug, while the straight key requires a 1/8 mono plug.
• Q: Can I use low-cost headphones with the FX-2?
• A: Yes, the unit has good volume, so it is acceptable to use low-cost phones. Simply connect your earbuds or headset to the phone’s port.
• Q: What should I do if there is sound distortion when the volume control is turned to maximum?
• A: If you experience sound distortion when the volume control is turned to maximum, reduce the volume until the distortion is reduced. In most cases, turning the volume back less than a quarter of a turn should solve the issue.
