The Thrane-Thrane EXPLORER 700 is a compact, high-performance satellite communication terminal designed for reliable voice, data, and fax services in remote locations. It features a robust antenna, intuitive user interface, support for multiple network services, and is built for harsh environmental conditions. This guide provides essential information for safety, initial setup, basic operation, and troubleshooting.
Key components: Satellite Antenna Unit (SAU), Terminal Unit (TU) with display and keypad, Power Supply Unit, Handset, and necessary cables.
| Feature | Description |
|---|---|
| Antenna Unit | Integrated stabilized antenna for satellite signal acquisition and tracking |
| Terminal Unit Display | Backlit LCD for status, menus, and call information |
| Keypad | For dialing numbers and navigating menus |
| Handset Port | For connecting the supplied telephone handset |
| DATA Port | For fax or data modem connection (RS-232) |
| POWER Port | For connection to DC power source (10.5-32 VDC) |
| POWER Button | Turns the terminal ON/OFF |
| MENU Button | Accesses the system configuration menu |
| MUTE Button | Mutes the handset microphone during a call |
| GPS Receiver | Integrated for position reporting and terminal setup |
Unpack and inspect all components. Choose a mounting location with a clear view of the sky.
WARNING! The antenna must have an unobstructed 360-degree view of the sky for initial acquisition. Do not mount near magnetic compasses or other sensitive equipment.
Power on the terminal; the system will perform self-tests and attempt satellite acquisition.
CAUTION! Ensure the terminal is powered from a stable DC source. Voltage spikes or drops can disrupt operation.
Primary control is via the Terminal Unit's keypad and display. Front Panel: POWER, MENU, numeric keypad, arrow keys, ENTER, and BACK.
Display Icons: Signal strength, network registration, GPS fix, call in progress, message waiting, battery/power status.
Menu Structure: SYSTEM (language, time, diagnostics), CALLS (call log, redial), MESSAGES (SMS, email setup), SETUP (network selection, data profiles). Status Screen: Shows primary information like signal level, position, and network name.
Handset: Plug directly into the TEL port on the TU. Data Device: Connect a fax machine or PC via the DATA port (RS-232) using a null-modem cable. Ethernet: If equipped, connect a LAN device via the RJ-45 port.
Tip: For permanent installations, secure all cables with cable ties and use drip loops to prevent water ingress.
Supports voice, fax, and data calls.
WARNING! Satellite call charges apply from the moment the connection is established until it is terminated. Be aware of your service plan.
Distress Alerting: Supports initiation of a distress alert via dedicated software or menu option (requires pre-configuration and subscription). Position Reporting: Integrated GPS provides location data for all calls and can be sent automatically. Call Priority: Ability to set call priority levels.
Power down before cleaning. Wipe the Antenna Unit radome with a soft, damp cloth. Keep vents on the Terminal Unit clear of obstructions.
CAUTION! Do not use solvents, abrasives, or high-pressure water on any part of the terminal. Inspect cables and connectors regularly for corrosion or damage.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No Power / Display Dark | Power connection, fuse | Check DC input voltage at terminal; verify inline fuse is intact; ensure power cable is securely connected. |
| "Searching for Network" or No Signal | Obstruction, cable, alignment | Ensure antenna has clear sky view; check antenna cable connections; perform a manual re-acquisition from the menu. |
| Cannot Make Calls | Network registration, account | Verify terminal is registered on network (icon on display). Contact service provider to check account status/SIM. |
| Poor Call Quality | Weak signal, interference | Check signal strength icon; ensure antenna is not obstructed; move away from potential sources of RF interference. |
| GPS Not Fixing | Antenna view, cold start | Ensure GPS antenna (integrated in SAU) has clear sky view. Allow up to 15 minutes for a cold start acquisition. |
Reset: Menu > System > Factory Reset (use with caution, erases settings).
