### Radio Controls Description

#### UM7 Radio

#### UN6 Radio/Cassette

#### ULO Radio/Cassette with Auto Tone

#### UNO Radio/CD with Auto Tone

#### UPO Radio/Cassette/CD with Auto Tone

#### Volume Control (VOLUME)

Important: When you jump start the vehicle, turn off the radio in order to avoid damaging the sound system.

A single multi-function rotary/push control provides the following functions:

• | The ON/OFF power

• | The volume control functions

Pressing the VOLUME knob will alternately turn the radio on or off. The volume control portion of the switch is a continuous rotary detent type with 36 detents per revolution. You may increase or decrease the volume over a range of 64 possible steps. This function will not be available during radio conditions that do not permit audio output, such as actively seeking/scanning in tuner mode or in tape mode. The radio display is not affected by volume changes. The volume function is replicated on the steering wheel control with separate volume buttons. Each momentary button closure causes the volume to increase or to decrease by 1 step. Pressing either one of these buttons causes the volume to change at a rate of 12 steps per second.

#### Stereo Indicator

The word STEREO (UM7) or the letters ST for all other models displays whenever a stereo broadcast is received.

#### Tune Control

On the UM7 and the UN6 models, the tuning control is a continuous rotary knob with 20 detents per revolution. Turn the control in the desired direction in order to tune the receiver:

• | Clockwise turning increases the frequency.

• | Counterclockwise turning decreases the frequency.

The UL0, the UN0, and the UP0 models, incorporate a vertically-mounted tuning control button.

• | Pressing the top portion of the button increases the frequency.

• | Pressing the bottom portion of the button decreases the frequency.

Frequency is either increased or decreased by one channel per detent.

Adjusting the tuning control will stop the SEEK and the SCAN functions. Tuning will then continue from the last frequency where the SEEK/SCAN function stopped. The tuning function is replicated on the steering wheel controls with the separate SEEK and SCAN buttons, when equipped.

#### AM/FM Switching

The AM/FM button is a sequencing (push-push) type that toggles between the AM, FM1, and FM2 bands The button is active anytime that the unit is on.

• | Pressing the AM/FM button while the radio is in the receiver mode changes the tuning to the frequency which was last selected on the next band.

• | Pressing the AM/FM button while the radio is in the playback mode causes the unit to switch into the receiver mode at the last selected band and frequency.

The following band switching sequence is from an initial state of FM1:

• | The first push toggles the receiver to FM2.

• | The second push toggles the receiver to AM.

• | The third push toggles the receiver back to FM1.

#### Recall Button (RECALL)

On the UM7 and the UN6 models, the RECALL activator is a knob. On all other models this activator is a button. Pressing this activator alternates the display between frequency information or time information. With the ignition turned to the OFF position, pressing this activator briefly turns on the display indicating the time of day.

#### Bass and Treble Controls (BASS) (TREB)

Bass and Treble controls are separate rotary control knobs. Each control is used for adjusting the system's audio frequency response. Operate the BASS function by first pressing and releasing the knob to the out position. This affects only the lower audio frequencies and has a center frequency of 60 Hz.

Operate the TREB (treble) function by first pressing and releasing the knob to the out position. This affects the high audio frequencies and has a center frequency of 10 kHz.

The center position of a given control indicates a flat response over that particular frequency range. Moving a control to the right of center position produces boost, while moving a control to the left produces a cut in frequency range related to that control. All units incorporate a loudness feature that automatically increases the bass bias at low listening levels.

On Auto Tone Control (ATC) models, any adjustment of these controls will activate the MANUAL tone control mode. The MANUAL tone mode will display on the ATC models. On non-ATC models bass and treble changes do not affect the radio display.

If you press any of the format presets, the receiver begins seeking. In order to store a format selection, the user selects a format type. Once a format type is selected, you store the format type in the selected format preset in the same manner as a normal preset stored (press and hold). When the storing process is complete, the display shows the following items:

• | The format button stored

• | The format type

An automatic seek will not occur after this process. A format seek invoked using the format presets cancels by pressing any button. Load the media in order for SOURCE to cancel the format seek. The defaults for the format preset buttons after battery cycle are ANY TYPE.

## Radio/Audio System Operation Pontiac

### Radio Controls

#### UM7 Radio

#### UN6 Radio/Cassette

#### UT6 Radio/Cassette with Equalizer

#### U1C Radio CD

#### UP3 Radio/CD with Equalizer

### Volume Control

Important: When you jump start the vehicle, turn the radio off in order to avoid damaging the sound system.

A single multi-function rotary/push control provides the following functions:

• | The ON/OFF power control

• | The volume control functions

Pressing the volume knob will alternately turn the radio on or off. The volume control portion of the switch is a continuous rotary detent type with 36 detents per revolution. You may increase or decrease the volume over a range of 64 possible steps. Thus function will not be available during radio conditions that do not permit audio output, such as actively seeking/scanning in the tuner mode or in the tape mode. The radio display is not affected by volume changes. The volume function is replicated on the steering wheel control with separate volume buttons. Each momentary button closure causes the volume to increase or to decrease by 1 step. Pressing either one of these buttons causes the volume to change at a rate of 12 steps per second.

### Stereo Indicator

The word STEREO (UM7), or the letters ST for all other models, displays whenever a stereo broadcast is received.

### Tune Control

The tuning control is a continuous rotary knob with 20 detents per revolution. Turn the control in the desired direction in order to tune the receiver.

• | Clockwise to increase the frequency.

• | Counterclockwise to decrease the frequency.

The frequency is either increased or decreased by one channel per detent.

Adjusting the tuning control will stop the seek and the scan functions. Tuning will then continue from the last frequency where the SEEK/SCAN function stopped. The tuning function is replicated on the steering wheel controls with the separate SEEK and SCAN buttons, when equipped.

### AM/FM Switching

The AM/FM button is a sequencing (push-push) type that toggles between the AM, FM1, and FM2 bands. The button is active anytime that the unit is on.

• | Press the AM/FM button while the radio is in the receiver mode in order to change the tuning to the frequency which was last selected on the next band.

• | Press the AM/FM button while the radio is in the playback mode in order to cause the unit to switch into the receiver mode at the last selected band and frequency.

The following band switch sequence is from an initial state of FM1:

• | The first push toggles the receiver to FM2.

• | The second push toggles the receiver to AM.

• | The third push toggles the receiver back to FM1.

### Recall Button (RECALL)

The format type 30 is reserved for emergency broadcast tests in the US. Format 31 is reserved for broadcast emergencies. Do not use the Format 31 as a search criteria. The format lists include several special types. Use ANY TYPE in order to select any RDS station. While displaying a search format, enabling seek or scan finds the next available RDS station with the selected format type. The display shows SEEK or SCAN and the format type while the function is engaged. When the radio stops on a station during scan, the PS name will display. When you select format seek or scan without first selecting a search format, the previously selected format will be used. If the receiver does not find a station after wrapping around the band twice, the receiver returns to the previous station. Cancel the format seek or scan by pressing any button. Load the media for SOURCE in order to cancel format seek or scan.

### Format Presets

The format presets feature allows the user to store and recall format types using the following keys:

• | FMT A

• | FMT B

• | FMT C

If you press any of the format presets, the receiver begins seeking. In order to store a format selection, the user selects a format type. Once a format type is selected, you may store the format type in the selected format preset in the same manner as a normal preset is stored (press and hold). When the storing process is complete, the display shows the following items:

• | The format button stored

• | The format type

An automatic seek will not occur after this process. A format seek invoked by using the format presets is cancelled by pressing any button. Load the media in order for SOURCE to cancel the format seek. The defaults for the format preset buttons after battery cycle are ANY TYPE.
