Cradle The cradle connects your Telit Sat 550 telephone to the car kit allowing you to use it with the micro telephone or in hands-free mode. When connected to the amplifier using a coaxial wire, the cradle amplifies the audio output, removes the echo, charges the Sat 550’s battery and keeps it charged, and connects the telephone to the vehicle IO devices.
The micro telephone is fitted with a 3 m wire for connecting it to the cradle via the 2.5 mm mono jack. When installing, position the microphone not further than 40 cm from the driver and secure it in position using the two- sided tape or the bracket provided, which is to be screwed to the vehicle using the two screws provided in the pack.
Indication of switching on By connecting the white wire to the vehicle‘s ignition you will avoid any possibility of the vehicle telephone running the vehicle‘s battery flat. In fact, the switching on indication will only allow the car kit to be switched on and off when the vehicle is switched on and off.
GSM external antenna (optional) An external antenna can be used to improve the telephone’s performance in GSM 900 MHz mode. This antenna must be connected via the TNC type connector, on the rear of the cradle, marked with a small black square. Data connector A serial RS232, 9 –pin port is provided on the cradle.
Installation Precautions The car kit must only be installed by trained technicians using the technical assistance provided at authorised service centres (a list of these centres is included in the pack). Any installation or repair that is not done correctly may be dangerous and cause damage to the car kit and the Sat 500, and will cause the guarantee to lapse.
Installation Example The installation of the car kit varies depending on the model of the vehicle. The diagram below shows a possible installation of the various components in the car kit. Manuale_551_Inglese_New Martedì 29 Agosto 2000 10.56 pagina 15...
Installing the car kit Installing the amplifier (ODU) Install the metal bracket for the amplifier and the four spacers (provided in the pack), by fixing it to a metal panel using 4 screws (not supplied). Note: Before beginning to install the amplifier (for example in the boot), check that it will be possible to connect it to the cradle using the 5 m long Globalstar wire (provided in the pack) and the magnetic external antenna (using the 2 m long antenna wire).

Connect the coaxial wire for the Globalstar magnetic external antenna to the red and black connectors on the amplifier. Metal lugs Globalstar external antenna connectors Globalstar wire connector Screw fixing to the bracket Insert the two metal lugs on the amplifier into the spaces provided on the bracket, then fix in place using the screw provided in the pack.
Installing the cradle Note: Position the cradle inside the vehicle so that it does not interfere with normal driving operations, is not exposed to streams of hot air coming from the vehicle’s heating system, and away from the airbag. Before installing the cradle bracket, check that it can be connected to the amplifier (using the 5 m long Globalstar wire), the microphone (using the 2.8 m long wire), the loudspeaker (using the 3 m wire), the micro telephone and the vehicle’s IO devices.

Connectors and keys on the cradle 5 4 11 13 12 8 Cradle connector – Sat 550. Connector Sat 550 – cradle. Cradle antenna connectors – Sat 550. Connector for external GSM 900 MHz antenna (optional). Globalstar wire for connecting the cradle to the amplifier. RS232, 9-pin data connector.
Installing the micro telephone Note: Install the micro telephone inside the vehicle near the cradle, being careful not to hamper normal driving operations and staying clear of airbag openings. Secure the micro telephone bracket on a flat surface inside the vehicle using two screws (not provided in the pack).
Installing the microphone Install the microphone in the upper portion of the vehicle body using the relevant plastic bracket and two screws (provided in the pack), or on the sun visor using the double-sided adhesive tape. The microphone must face the driver’s mouth and not further than 40 cm from his mouth.
Installing the speaker For best results, the speaker should be installed at least one metre from the microphone and not facing it. Remove (if the speaker is to be fixed) the speaker bracket by exercising gentle outward pressure on it. Secure the bracket on a flat surface inside the vehicle using two screws (not provided in the pack).
Connecting to vehicle IO devices Ensure that the vehicle is switched off and that the battery terminals have been removed before connecting the wires. Connect the red and then the white wire only after all the other wires have been connected. Ensure that the connections have been formed tightly.
Advice for wire routing Where possible use existing ducts. When choosing a route for wires, ensure that they do not hamper the movement of pedals, seats or the handbrake. Position the wires so that they do not interfere with other electronic devices.
Using the car kit Placing the Sat 550 in the cradle and removing it To avoid damaging the Sat 550 telephone, before placing it in the cradle check that the yellow key at the top of the cradle is pressed and the Sat 550 is switched off.
Switching on the telephone and the car kit The telephone and the car kit switch on automatically when the vehicle‘s ignition is switched on (if the white wire has been connected). For information on operating the Sat 550, consult its instruction manual. If the Sat 550 is correctly placed in the cradle, the display will show the symbol H.
Adjusting the volume in hands-free mode To adjust the conversation volume when in hands-free mode, merely press the keys on the side of the cradle. The upper key increases the volume, the lower decreases volume. The volume of the ring can be set using the same keys while the telephone is in stand-by mode.
Adjusting the volume on the micro telephone The volume of a conversation in private mode can be adjusted by using the volume adjuster on the side of the micro telephone. Connecting to a Personal Computer A laptop PC can be connected to the car kit, using the RS232, 9-pin connector, to transmit data and faxes.
