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.
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.
