The mobile telephone includes voice recognition which allows the following procedures to be done by voice usage only:

These features operate in conjunction with the following systems:

The voice recognition will recognize the user's voice without being programmed. The system has 400 different voice types that are automatically programmed into the voice recognition feature. The system uses a hands-free microphone for voice recognition.

Cellular Telephone Handset

The cellular telephone handset is located in the forward compartment of the console. Place the handset in the ON position in order to place or receive calls.

Hands Free Operation

Hands free operation allows the occupants in the vehicle to converse without using the handset. Hands free operation is automatic during the conversation. The conversation is carried on by the use of the hands-free microphone and the audio system speakers.

Cellular Microphone

The cellular microphone is located in the inside rearview mirror. The microphone operates while in hands-free mode. While in the hands-free mode, the user may mute the microphone during a call. Use the mute function in order to speak privately with a passenger.

Cellular Telephone Module

The cellular telephone module is located in the rear compartment, behind the rear shelf trim, mounted to the rear shelf carrier. The module provides the following features:

Cellular Telephone Antenna

The 3-decibel noiseless antenna is mounted on the right side of the rear window glass.

Celular Telephone Circuit Description

Power is supplied from the AUDIO fuse in the rear fuse block via CKT 2240 to the cellular telephone module. The module is grounded via CKT 1051 to ground G401.

The module controls the cellular telephone handset power via CKT 1941 and CKT 2526. The module controls the handset display and transfers handset/keypad data on CKT 679, CKT 1156 and CKT 1798.

The handset communicates shielded signals to the cellular telephone module as follows:

When the handset is placed in the docking station, the system operates in the hands-free mode. This mode enables the hands-free microphone to pick up the the driver's voice. During hands-free mode, the radio amplifier mutes the radio or cd changer audio signal and sounds the the incoming cellular telephone voice audio signal through the speakers. Removing the handset from the docking station disables the hands-free feature, which allows the radio amplifier to play the radio or cd changer audio signal. The handset must be held to the driver's head for voice conversation.

The cellular telephone microphone is wired to the cellular telephone module via CKT 655 and CKT 814. During hands-free operation, the module provides mono audio output to the vehicle audio system on CKT 658 and CKT 659 .

The module communicates on the Class 2 serial data line CKT 1807, which the module uses for transmission of messages, status and diagnostic information.
