Applies to: Match Terra 400 and part number TR400 on the installed unit. The shared manual also names Oceana 400; do not extend its instructions to Terra 800, an IsatDock cradle or another Beam terminal. Record the existing antenna and cable-kit labels without disconnecting them.
Match your symptom
| What you see | What to do next |
|---|---|
| Audible alarm | If the terminal sounds an alarm, use its normal power control to switch it off safely and stop. Beam associates this alarm with an RF short; leave antenna and cable fault isolation to a qualified technician. |
| Searching or calls fail | Ask the airtime provider to confirm activation, restrictions and outages for this account and location. Discontinued hardware is not proof that the account is usable today. Do not guess PIN or PUK codes. |
Work through these checks
Record registration state
Record the indicator colour and exact message before changing anything. Distinguish searching for the network from registered with poor signal.
What the result means: For Terra/Oceana 400, Beam describes green as registered with good signal and yellow as registered with poor signal. Record the displayed state and whether an ordinary call connects; the colour alone does not establish emergency-call reliability. Do not place test emergency calls.
Observe the existing antenna path
From a safe accessible position, note new obstructions and visible cable damage. Do not climb, move the fixed antenna, disconnect powered RF cables or substitute a cable because its plug fits.
What the result means: This overview describes an existing installation. Leave fixed power, antenna positioning and cable replacement to a qualified installer. A cable with a matching plug is not proof of the correct active/passive antenna arrangement. Ask Beam to confirm the exact cable and antenna combination before ordering parts.
Check the service separately
Ask the airtime provider to confirm activation, restrictions and outages for this account and location. Discontinued hardware is not proof that the account is usable today. Do not guess PIN or PUK codes.
What the result means: For support, supply the TR400 label, antenna and cable-kit identification, LED state, exact message and whether the problem affects voice or data. Keep account identifiers private. Historical modem and software instructions may target older computers; confirm supported software with Beam rather than installing unrelated drivers or firmware.
When to stop and get help

What to tell support
For support, supply the TR400 label, antenna and cable-kit identification, LED state, exact message and whether the problem affects voice or data. Keep account identifiers private.

Common questions
Does yellow mean no registration?
For Terra/Oceana 400, Beam describes green as registered with good signal and yellow as registered with poor signal. Record the displayed state and whether an ordinary call connects; the colour alone does not establish emergency-call reliability. Do not place test emergency calls.
