HINTS FOR BEST RECEPTION:

The AM antenna is located inside the cabinet of the unit. If AM reception 
is weak, change the position of unit until the internal antenna picks up 
the strongest signal.
To insure maximum FM tuner reception, the Telescopic Antenna should 
be fully extended and rotated to obtain the best possible station reception.
