ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position and the time button is pressed.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
Clock Setting Procedure
1. Turn the ignition switch to the ON or ACC position
and press the time button. Using the tip of a ballpoint pen
or similar object, press either the hour (H) or minute (M)
buttons on the radio.
2. Press the H button to set hours or the M button to set
minutes. The time setting will increase each time you
press a button.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.

To Set The Radio Push-Button Memory

to push-button memory, press the SET button. SET 1 will
now show in the display window. Select the ª1±5º button

that button. If a button is not selected within 5 seconds
after pressing the SET button, the station will continue to
play but will not be locked into push-button memory.
You may add a second station to each push-button by
repeating the above procedure with this exception: Press
the SET button twice and SET 2 will show in the display
window. Each button can be set for SET 1 and SET 2 in
both AM and FM. This allows a total of 10 AM and 10 FM
stations to be locked into push-button memory. The
stations stored in SET 2 memory can be selected by
pressing the push-button twice.
