14 Preliminary Draft
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-9a) permits communication with
the satellite when the phone is installed in the cradle.
ODU cables
The ODU cables consist of two lengths of paired coaxial cables (GCK-11a,
GCK-12a) that connect the ODU to the cradle (The GCK-12a pigtail from
the Cradle connects to the GCK-11a pigtail from the ODU). 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
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-2a) with a
mounting plate. It is connected to the GEM (GCK-1a) via a 6-position RJ-
45 connector.
