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.
Privacy headset and adapter
The privacy headset (GCK-4) offers more privacy during a call
and is connected to the GEM through a headset adapter. The
headset adapter (GCK-5) attaches to the cradle (GCK-2a) with
velcro and is plugged into the GEM (GCK-1a).
Note
The optional privacy headset cannot be used at the same
time as the privacy handset, and it will only work with
the optional headset adapter. See your service provider
for this and the other optional accessories.
Cellular antenna (not included)
The cellular antenna is attached with a mini-UHF type
connector to a pigtail (GCK-13) on the cradle and is used to
enhance reception when the phone is in the cellular mode. This
is not included with the car kit.
Data cable (not included)
A serial port data cable, RS-232, 9-pin, can connect a PC to the
GEM (GCK-1a) so that the phone can send and receive data.
