Control Functions

The premium sound system consists of six speakers (two high frequency instrument panel speakers, two premium front door speakers and two premium rear speakers). The door and instrument panel speakers are wired in parallel. Separate signal return wiring to each speaker is used. The four-channel amplifier is in operation and is part of the circuit at all times.

 

Electronic Search Radio (ESR)

Three types of radios are available on the Mustang: the Electronic Search Radio (ESR), the Electronic Stereo Cassette (ESC) and the Compact Disc Receiver (CDR). On the Cobra, the Compact Disc Receiver (CDR) or the Premium Analog Cassette/Multi Disc Controller (PAC/CDDJ) is available.

The Electronic Search Radio (ESR) contains some features which may not be familiar to the user. These instructions will explain the features.



The following is a description of the various controls:

  1. POWER: Push to turn ON, push again to turn OFF.
  2. BAND INDICATOR: Indicates if band is in AM, FM1 or FM2 setting.
  3. STATION INDICATOR: Indicates radio station frequency in radio mode.
  4. TUNE: This button is used to change the frequency up or down one increment at a time by pressing the right (>) or left (<) side of button. To change frequencies quickly, press and hold either right or left side of button.
  5. SEEK: Push right (>) side of SEEK button to tune radio to the next higher frequency station. Push left (<) side of SEEK button to tune radio down to next lower frequency station.
  6. CLOCK: The clock can be set at any time (Radio, Power "off," ignition "off"). First depress the CLOCK button and simultaneously depress "SEEK (<)" to advance hours, or "SEEK (>)" to advance minutes. The CLOCK button must be held in throughout the time setting operation. Seconds are reset to zero when the CLOCK button is released.
  7. MEMORY BUTTONS: The six memory buttons are used to store preferred broadcast stations in radio memory. To store a station, tune to desired station, push memory button in and hold for approximately two seconds until station sound returns, then release button. Repeat process for each memory button. Once a station is stored in memory, pushing a memory button for less than two seconds will cause radio to turn to stored station. All six memory buttons will store a station on AM, FM1 or FM2 for a total of 18 storable radio stations.
  8. AM/FM: Each successive push, when in radio mode, will select AM, FM1 or FM2 as indicated by band indicator in display window.
  9. VOLUME: Push right (+) side of VOLUME button to increase volume. Push left (-) side to decrease volume. If VOLUME button is held to the right or left, the volume will continuously increase or decrease (bars in display will show relative volume) until button is released.

    NOTE: If the VOLUME button is set above a preset listening level when ignition switch is turned off, when ignition switch is turned back on, the volume will return to a nominal listening level. However, if radio power is turned off with the POWER button before ignition is turned off, volume will return to the position it was set at previously, when radio power is switched back on.
