FBB error messages often indicate connectivity or configuration issues. Common errors include “No Signal,” “Login Failed,” or “Antenna Fault.” These messages can result from misaligned antennas, expired airtime, or software glitches. To resolve these, first, check the antenna alignment and ensure it is unobstructed. Next, verify your airtime balance and subscription status. If the error persists, restart the terminal and update its software. For persistent issues, consult the user manual or contact technical support. Understanding these error messages can help you troubleshoot effectively and minimize downtime.
