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.
How it connects
- Installed external antenna Model-matched antenna cable kit
- Terra 400 · TR400 Existing telephone connection
- Telephone and account
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.
Lights and messages
- 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.
- An audible RF-short alarm is a stop condition. Beam advises removing power to avoid further damage. Use the normal safely accessible power control, keep the unit off and contact the installer; do not repeatedly reconnect power or isolate antenna cables as a household test.
A light is one clue, not a complete diagnosis. Match the indicator’s label and the on-screen message.
Before buying parts
- 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.
