Introduction

The FDU-XT (Fixed Docking Unit) is a home/office docking adapter that allows you to use Thuraya satellite services in indoor environments. It provides additional flexibility and convenience when using Thuraya XT-series handsets.
In addition, FDU-XT and its accessories are designed to meet Thuraya’s specifications and quality standards.
This indoor enabler enhances the capabilities of your Thuraya handset to meet your communication requirements, both in the home and in the office.
When a Thuraya handset is used with FDU-XT, the handset becomes an indoor communication center providing voice and data communication.

Package Contents

The FDU-XT package consists of the following items:

Installation Instructions

After unpacking, please make sure that your FDU-XT and all its accessories are fully ready for installation. Please read the instructions carefully. If you encounter any difficulty in installation, contact your Service Provider for assistance.

3.1. Antenna Installation
The FDU-XT antenna set consists of the following components:

  1. Satellite antenna with mounting adapter.
  2. Satellite antenna cable to connect the satellite antenna to the FDU-XT (25 m).
  3. GPS antenna with attached coaxial cable to connect to the FDU-XT (25 m).

3.2. Installing the Satellite Antenna
The satellite antenna is a rectangular patch antenna and is supplied with mounting brackets.
3.2.1. How to install the Satellite Antenna

  1. Mount the antenna onto any suitable fixture (mounting pole or wall) using the provided mounting brackets and bolts. The antenna should face the Thuraya satellite (see 3.2.2 for antenna orientation).
  2. When installing the antenna, make sure the connectors are accessible when mounted.
  3. Connect the coaxial cable to the antenna connector located at the base of the satellite antenna and tighten it properly by turning it clockwise. Leave enough length for a small loop and secure the rest of the cable using the cable ties.
  4. Connect the other end of the satellite antenna cable to the reverse side of the FDU-XT marked “SAT”.THURAYA FDU XT Satellite Phone - Figure 3

3.2.2. How to align the Satellite Antenna
Satellite based communication requires a direct line of sight to the satellite to achieve optimal signal strength. Therefore, the antenna must first be mounted in a location facing the satellite where it can then be finely adjusted for maximum reception.
The locations of the Thuraya satellites are on a geostationary orbit (at the equator) at a more or less constant position:
Satellite based communication requires a direct line of sight to the satellite to achieve optimal signal strength. Therefore, the antenna must first be mounted in a location facing the satellite where it can then be finely adjusted for maximum reception.
The locations of the Thuraya satellites are on a geostationary orbit (at the equator) at a more or less constant position:

  • Thuraya-2 satellite at 44 degrees east of the zero meridian (approximately over Somalia)
  • Thuraya-3 satellite at 98.5 degrees east of the zero meridian (approximately over Sumatra).

Antenna orientation:

  • Align your antenna towards the Thuraya-2 satellite if your location is within the Thuraya-2 coverage area (Europe, Africa, Middle East).
  • Align your antenna towards the Thuraya-3 satellite if your location is within the Thuraya-3 coverage area (Asia, Australia).
    In the overlapping areas, you can approach either of the two satellites and choose the satellite with the stronger signal.

If you require an accurate antenna alignment, you can retrieve precise directions from your current location to the satellite (azimuth and elevation angle) by either of the following methods:

  1. Acquire your current GPS position data with your Thuraya satellite phone (function ‘Current position’), press Option and send this data by SMS to the short code 1300. You will then receive the directional data from your location to the respective Thuraya satellite.
  2. There are several independent websites where you can retrieve directional data to a specific satellite by entering your current location (www.dishpointer.com, www.satsig.net or others).

3.3. Installing the GPS Antenna
The GPS antenna comes with an attached coaxial cable to connect to the FDU-XT unit.

  1. Find an appropriate location to mount the antenna.
    Make sure the antenna has a clear view of the sky.

  2. Mark locations of the “screw holders” on the surface/rooftop for fixing the antenna.

  3. Drill holes of adequate depth on the surface.

  4. Keep the antenna in place so that the drilled holes and the screw holders line up.

  5. Fix the antenna securely using the screws provided.

  6. Connect the free end of the attached cable to the GPS antenna connector marked “GPS” on the reverse side of the FDU-XT.
    Note: Maintain a distance of 0.5 to 1 meter between the GPS and SAT antenna.

3.4. External Accessories
In order to use the FDU-XT, a Thuraya XT-series satellite phone with an active SIM-card is required. In addition the following external devices can be used with the FDU-XT:

  1. Ana log extension phone
  2. PC or laptop for data transfer
    Note: The RJ-11 cable should be 2-wire inner at both ends.

  2. Press # → Old PIN (4 digits) → → New PIN (4 digits) → (e.g.: # 0000 1234 )
  3. Hang up the phone after hearing the beep which indicates the confirmation of the PIN change.

Please make sure you do not forget the new PIN code, otherwise you need to bring the FDU­ XT to the Service Center in order to reset the unit.

Troubleshooting

Your FDU-XT does not contain consumer serviceable components. You are advised not to carry out any kind of troubleshooting. In case you face any problems, contact the nearest service center. Only authorized service personnel can repair the equipment.
Use only the antennas and cables that have been provided with the unit or that have been specifically designed for your FDU-XT.
Unauthorized antennas, cables and cable length modification or attachments could damage the FDU-XT and may violate the relevant regulations, causing loss of performance and radio frequency (RF) energy above the recommended limits. If your FDU-XT’s antenna gets damaged, please take it to an authorized Service Provider.

  • Do not place the FDU-XT in a wet area.
  • Do not expose the FDU-XT to temperatures higher than +55°C Celsius or less than 0°C Celsius.
  • Do not expose the FDU-XT to moisture, dust etc.
  • Do not expose the FDU-XT to direct sunlight.
  • Do not disassemble the FDU-XT; this will void your warranty.
  • Do not store it in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.
  • Do not drop, apply pressure or shake it. Rough handling can break internal circuit boards.
  • Do not use chemicals, cleaning solvents, or strong detergents to clean it. Wipe it smoothly with a soft cloth.
  • Do not paint it. Paint can clog the device’s moving parts and prevent proper operation.

If the FDU-XT, the phone, battery, charger or any accessory does not function properly, take it to your nearest authorized service center. The personnel there will assist you, and if necessary, arrange for service.

Common Problems

  • Thuraya handset is not properly docked.
  • Thuraya handset is switched OFF.
  • There is not enough satellite signal strength (minimum of two bars should be shown on the handset display, otherwise adjust the antenna).
