FM outdoor antenna
If the reception is not very clear with the supplied FM antenna, the use of an outdoor antenna is
recommended.
Please make sure that you follow the considerations below regarding the location.
• Keep the antenna away from noise sources (neon signs, busy roads etc.).
• It is dangerous to put the antenna close to power lines. Keep it well away from power lines, etc.
• 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.
