Lights and messages
- Inspect the BAM alert text and state before resetting. Acknowledging or silencing an alert does not remove its cause. Separate network rejection from optional Bluetooth hardware and retain a diagnostic report for authorized support.
A light is one clue, not a complete diagnosis. Match the indicator’s label and the on-screen message.
Before buying parts
- Do not open units or connect/disconnect powered antenna cables. Keep clear of the transmitting antenna; use an authorized marine installer for wiring or antenna work. Preserve configuration and contacts; factory reset is destructive.
These are compatibility notes and official reference links. Confirm the fault and exact part before buying.
