AM loop antenna
Connecting antennas
Connecting the AM loop antenna
1. Press down the lever.
2. Insert the end of the
cable into the hole.
3. Release the lever.
The lever will return to the
original position.
Either of the split ends of the AM antenna can be connected to
either terminal. Unlike speaker cabling, there is no polarity for
AM broadcast signals.
The AM loop antenna is for indoor use only. Set it in the direction
and position where you receive signals clearly. Put it as far away
as possible from the HT-R490, televisions, speaker cables, and
power cords.
When reception is not satisfactory with the attached AM loop
antenna alone, connection of an outdoor antenna is recommended.

To the use the tuner of HT-R490, it is necessary to prepare the
supplied FM and AM antennas.
Adjustment and placement of the FM and AM antennas for
better reception must be done while listening to a station
broadcast.
If better reception cannot be obtained, then placement of an
outside antenna is recommended.
Connecting the FM indoor antenna
1. Strip away the insulation from the end of the
cord.
2. Fully insert the stripped end of the cord.
The FM indoor antenna is for indoor use only. During use, extend
the antenna and move it in various directions until the clearest
signal is received. Fix it with push pins or similar implements in
the position that will cause the least amount of distortion.
If the reception is not very clear with the attached FM indoor
antenna, the use of an outdoor antenna is recommended.
Assembling the AM loop antenna
1. Rotate the outer frame of
the antenna.
2. Insert the bottom edge of
the outer frame into the
groove on the stand.
3. Extend the antenna cord.
