Connecting an AM outdoor antenna
When reception is not satisfactory with the
supplied AM loop antenna alone, connection of
an outdoor antenna is recommended.
The outdoor antenna will be more effective if it is
stretched horizontally above a window or outside.
• Do not remove the AM loop antenna.
• To avoid the risk of lightning and electrical
shock, grounding is necessary. Follow item 19
of the “Important Safeguards” on page 3 when
you install the outdoor antenna.
