To store stations in memory
Any FM station can be storedon any
through Q2U by
button marked
first tuning in the desired station, de­
pressing the button desired and hold­
ing it until the display has changed
from the "old" setting to a "blank" and
then to the new station to be stored.
Showing the "old" setting first allows
for reconsideration of the decision to
store. If it is desirable to leave the
"old" station in memory rather than
exchanging it with the "new" one,
quickly release the button. The "old"
station will remain in memory.
Any AM station can be storedsimi-
larly on any button marked

Stereo reception
The stereo indicator
a stereo program in the AM or FM
band is received.
Note: The radio receives AM stereo
programs which are broadcast via the
C-Quam®* AM stereo system.
The radio is equipped with an auto­
matic stereo/mono blend switch that
electronically switches to mono for
clear reception if a weak signal is
received.
The stereo indicator will remain lit
even if the receiver has changed to
the mono mode and will turn off at an
antenna signal considered insufficient
to provide acceptable reception
quality.
Although FM is normally static free,
reception quality can be limited by
geographic and atmospheric condi­
tions, station strength and distance
from the transmitter. Buildings or other
obstructions can cause momentary
static, flutter or station swapping. If
good reception cannot be obtained,
tune to a stronger station.

In the event that it is important to listen
to a weak station or to a strong station
lights up if
that is masked by terrain-induced
noise or interference problems, the fol­
lowing steps can be taken to increase
the listenability of the station.
Fringe area AM and FM reception of
weak stations can be improved by first
insuring that the antenna is at its max­
imum height and then reducing the
treble and bass settings as required to
filter out as much background noise as
is needed.
FM noise problems that are caused by
urban and hilly conditions may be re­
duced by lowering the treble setting
until the pops and hisses associated
with this type of terrain are reduced to
acceptable levels.
AM reception difficulties caused by
strong adjacent stations or nighttime
atmospheric conditions may be re­
duced by fine tuning the selected sta­
tion with the two fine tuning buttons.
