Pressing the PWR knob alternately turns the radio ON or OFF. On the UM7 and the UN6, the power knob is a rotary ON/OFF switch that is shared with the volume control.
A single multi-function rotary/push control provides the following functions:
• | The on-off power |
• | The volume control |
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. The volume function will not be available during radio conditions that do not permit audio output. Actively seeking/scanning in tuner or tape modes does not permit audio output. The volume control functions the same in both Bose® and non-Bose® applications. Volume changes do not affect the radio display. The volume function replicates on the steering wheel control with separate volume buttons. Each momentary button closure causes the volume to increase or decrease by one step. Pressing either one of these buttons causes the volume to change at a rate of 12 steps per second.
The word STEREO (UM7), or ST for all other models displays whenever a stereo broadcast is received.
The tuning control is a continuous rotary knob with 20 detents per revolution. In order to tune the receiver, turn the control in the desired direction. Turning the controls clockwise increases the frequency. Turning the controls counterclockwise decreases the frequency. Frequency increases or decreases by one channel per detent.
Adjusting the tuning control stops the SEEK and the SCAN functions. Tuning continues from the frequency that the receiver was at when you last stopped the function. The tuning function replicates on the steering wheel controls with separate TUNE buttons, if equipped.
The AM/FM button is a sequencing, push-push type that toggles between the following bands:

The button is active anytime the unit is on. Pressing the AM/FM button while in the receiver mode will change the tuning to the frequency last selected on the next band. Pressing the AM/FM button while in the playback mode causes the unit to switch into the receiver mode with the last selected band and frequency. From an initial state of FM1, the band switch takes the following sequence:
Pressing the knob RCL, or the RECALL button alternates the display between frequency or time information. With the ignition in the OFF position, pressing the RCL or RECALL button briefly turns on the display indicating the time of day.
The bass and treble controls are separate rotary control knobs. Use these controls in order to adjust the system's audio frequency response. The knob operates the BASS function. The BASS function affects only the lower audio frequencies. The bass function has a center frequency of 60 Hz. The TREB function operates by turning the knob. The TREB function affects the high audio frequencies. The TREB function has a center frequency of 10 kHz. The center position of a given control indicates the flat response over that particular frequency range.
Moving a control to the right of center position produces boost. Moving a control to the left of center position produces a cut in frequency range related to that control. All units incorporate a loudness feature that automatically increases bass bias at low listening levels. On the Auto Tone Control (ATC) models, any adjustment of the controls activates the MANUAL tone control (ATC) mode. The adjustment of the controls establishes the MANUAL ATC mode as default. The MANUAL tone mode displays on the ATC models. The bass and treble changes do not affect the radio display on non-ATC models.
