Car stereo muting (STEREO MUTE)
The phone provides a feature to mute the car stereo automatically during a
conversation which is convenient and provides for safer hands-free
operation. When the phone rings, the green fused lead provided for the
stereo mute feature goes to ground.
Note
This feature requires a car stereo that supports it.
Ignition sense
The ignition sense feature prevents the car kit from draining the vehicle’s
battery by executing an auto power off 30 seconds after the ignition key has
been turned off, if not currently in a call. The yellow wire of the car interface
cable (GCK-7) is used for the ignition sense feature. The use of ignition
sense is recommended to prevent accidental draining of the vehicle’s
battery. The wire is connected via a fuse to the vehicle’s ignition. Do not
connect it directly to the high voltage sections of the ignition circuit.
Outdoor unit
The Globalstar outdoor unit (ODU/GCK-9) permits communication with
the satellite when the phone is installed in the cradle.
ODU cables
The ODU cables consist of a pair of coaxial cables (GCK-10, GCK-11) that
connect the ODU to the cradle. Use only the ODU cables that come with
your car kit when connecting the ODU. Do not cut or modify the ODU
cables.
Caution
Note that DC voltage exists in the central conductor of the ODU
cable. Be sure that the cable connector is installed inside the
vehicle.
Optional accessories
ODU cable
If a longer transition cable is needed, an optional longer cable is available.
Contact your service provider for more information. Use only the ODU
cables that come with your car kit when connecting the ODU. Do not cut
or modify the ODU cables.
Privacy handset
The privacy handset (GCK-8) offers more privacy during a call than the
hands-free mode and can be attached to the cradle (GCK-2) with a
mounting plate. It is connected to the GEM (GCK-1) via a 6-position RJ-45
connector.
