Connecting antennas
To TV (or VCR)
If the reception condition cannot be improved by adjusting the
provided antenna, install an outdoor antenna and connect it to this unit.
Connecting an FM outdoor antenna
Please make sure that you follow the considerations:
• 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.

Connecting an AM outdoor antenna
An outdoor antenna will be more effective if it is stretched
horizontally above a window or outside.
Notes:
• Do not remove the AM loop antenna.
• 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.
