Remote control unit Dry cell batteries (SIZE "AA*(RE6P)}
Setting up the AM Antenna
+ Insert the claw on the bottom of the antenna into the hole in
the leg.
+ Place the antenna on a level surface and rotate it to locate the
orientation that yields the best reception.
+ Use the attachment hole in the leg to screw to wall or other
location, then insert the claw on the bottom of the antenna
into the hole in the leg (fixing the antenna in the direction that
gives the best reception).
@) Lead wire @ Leg @® Lead wire
NOTE FOR FM ANTENNA:
Stretch the antenna out to its full length, and affix it to a wall,
ete.
NOTE FOR AM LOOP ANTENNA:
The antenna should be placed at a distance from the receiver,
and should not be allowed to touch metallic objects.
Avoid placing it near CD players, personal computers, television
sets, and other devices generating radio frequencies.
EXTERNAL FM ANTENNA
The main advantage of FM over AM is the quality of the broad-
cast signal. In order to benefit fully from the high signal quality
of FM broadcasts, it is recommended that a special-purpose FM
antenna be installed. In weak signal areas, a multi-element (3-
element, 5-element, 7-element, etc.) antenna should be used.
FM OUTDOOR ANTENNA CONNECTIONS
There are two ways of connecting the FM antenna to the an-
tenna input terminals: with a 300 twin-lead feeder or with a 75
coaxial cable .
To get the most performance from the receiver, a 75 coaxial
cable is recommended since it is more immune than the twin-
lead feeder to noise and interference from external sources. If
an FM antenna has already been erected outdoors, connect it,
referring to the figure.
GROUNDING
Grounding is recommended if reception of FM programs is im-
paired by noise. To ground, connect a thick polyvinyl insulated
wire to the GND terminal and attach the other end to a metal
water pipe or grounding bar or wind it around a copper plate
and bury it.
NOTE:
Never connect a wire to a gas pipe for grounding since sparks
May ignite the gas.
EXTERNAL AM ANTENNA
If it is not possible to obtain adequate AM reception even by
changing the orientation of the AM loop antenna, a separate in-
door antenna, or an outdoor antenna should be installed.
INDOOR AM ANTENNA
Use a polyvinyl insulated wire (5 - 6m) and connect one end to
the AM antenna terminal and affix the other end to the wall or
ceiling, as high as possible.
OUTDOOR AM ANTENNA
if reception quality is not improved sufficiently even when an
indoor antenna is used, a polyviny! insulated wire should be in-
stalled outside and fixed in place.
NOTE:
Do not detach the AM loop antenna when using an indoor or an
giideer AM antenna.

CONNECTIONS
When not using the unit for a long period, disconnect the power, vr

+ Set the antenna on a level surface, and point in the direction
that gives optimum reception.
+ Do not install the antenna in locations where it touches the
AM loop antenna cover of the receiver or other meta! objects, or near a CD
player, personal computer, or television set.
