How it connects
Match JUE-87 and indoor unit NTF-318 against manual 7ZPSC0444, September 2012 Edition 1. POWER means power is present; READY means the NCS TDM carrier is received; COMM off can simply mean idle. Record the exact WARNING/CAUTION text and alarm-history time. Window overflow and binary-text display messages are not proof of antenna failure; No Position Data needs a separate position-input investigation. Preserve stored messages. Do not clear history, format USB, reset settings or start PV, distress or SSAS tests as troubleshooting. Follow the vessel’s qualified operator procedure. This archived manual does not establish current service or compliance.
