SAILOR SC4150 Installation Manual Single-channel Unit
Introduction Congratulations on your new Iridium handset or PSTN (Public Switched Telephone Network) telephone. Your Iridium system is a modular system that consists of an antenna, transmitter/receiver, handset and/or desk unit, and optional PSTN telephone/PBX (Private Branch Exchange) switchboard. You can operate the Iridium system in voice mode from a handset, desk unit, and/or PSTN telephone. To the system you can connect up to five handsets or desk units and one PSTN telephone or PBX switchboard.

The temperature must not exceed 55° C.
SC4150 2.3 Installation How to Mount the Satellite Transceiver Box Fix the satellite transceiver box to the wall using the four screws included in the package. The screws are positioned as shown below: First tighten three of the screws. The wall surface should be plane. If there is a discrepancy in planeness exceeding 1 mm, level the discrepancy up by shims or washers under the fourth screw before this is tightened.
SC4150 Installation 2.4 How to Put on the Finishing Cover When the satellite transceiver box has been mounted on the wall, put on the finishing cover. The small lid in the finishing cover should be shut. Press the hooks inside the finishing cover down on the two thin edges of the satellite transceiver box. While pressing, let the two plastic spears inside the finishing cover into the two square holes of the satellite transceiver box.
SC4150 2.5 Installation How to Insert the SIM Card First, open the small lid in the finishing cover protecting the SIM card reader. Then go through each of the following steps: Unlock the SIM card holder by pushing the lock with your finger nail. Lift the SIM card holder so that the slot points upwards. Insert the SIM card in the slot. Make sure that the cut-off corner of the card is placed as shown in the picture.
SC4150 Installation 2.6 How to Remove the Finishing Cover You may need to dismount the satellite transceiver box from the wall, e.g. in connection with service. For access to the mounting screws, the finishing cover can be removed from the satellite transceiver box as follows: Put a screwdriver into the slot in the printed circuit board beside the SIM card reader, and press gently to unhook the plastic spear.
SC4150 2.7 Installation How to Change the Antenna Cable Position In some installations, it may be convenient to change the antenna connection to a position at the top of the satellite transceiver box. First face the back of the satellite transceiver box. Now, unscrew the four screws holding the L-band transceiver (LBT) unit. Note that you will need both the screws and the spring washers later on.
SC4150 Installation Place the demounted LBT unit near the satellite transceiver box, without disconnecting it. Rest the bottom of the satellite transceiver box on a block of soft wood. Use a hammer and a mandrel to hammer out the brick indicated by a recess in the top of the aluminium case. Be careful not to pinch, squeeze, or in other ways damage the ribbon cable. If the hole is not “clean”, use a file or pliers to remove the rest. The transceiver box can now be mounted on the wall.
SC4150 2.8 Installation Installation of the Antenna One of the advantages of this equipment is the easy-to-handle, lightweight and rugged antenna. Because the IRIDIUM ® system is characterised by a good link margin, the antenna is a passive quadrifillar helix type, requiring no external power supply and consisting of only nonmoving parts. The following figures show the antenna and the two different mounting accessories available: The mounting bracket in fig.
SC4150 Installation Precautions In order to avoid interference or any other kind of disturbances from other systems on board, there are a few precautions to take note of: Radars According to any installation guide for radars it is of vital importance that any other units are kept outside the radiation beam of the radar. Please consult fig. 3, showing what area to avoid: Unobstructed view until 10° below the horizon Avoid interference e.g.
SC4150 Installation Inmarsat equipment The operating frequency bands of the iridium and Inmarsat systems are neighbours, and it is not in any way by any technical solution possible to completely separate these bands. This means that interference from Inmarsat can be expected, especially if the antennas are placed near each other. The distance between the antennas Should be as far as possible.
