Connecting antennas

Connecting an FM outdoor antenna

Make sure to follow the general rules given below:

•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, transformers, etc.

•To avoid the risk of lightning and electrical shock, grounding is necessary. Follow item 14 of the “Important Safeguards” on page 2 when you install the outdoor antenna.

Directional linkage

Do not use the same antenna for both FM and TV (or VCR) reception since the FM and TV (or VCR) signals can interfere with each other. If you must use a common FM/TV (or VCR) antenna, use a directional linkage type splitter.
