Connect the supplied AM antenna plug into
the Motorola-style AM antenna jack as shown
below. Extend the wire within the wall if it was
not previously installed.

External Antenna Installation

To improve radio reception external antennas can be used. Before committing to the cost and difficulty of external
antennas it is advisable to try moving the antennas within the wall to see if a suitable position can be obtained. Moving
the antenna wires up the wall with a non-metallic object will generally yield better reception. If this does not yield the
desired results, then an attic-mounted antenna will likely work.
If an attic-mounted antenna is to be installed it is recommended that the installation be performed by a qualified
person(s). Extending the length of the AM wire with a single conductor can improve reception. For the FM antenna
it is recommended that a coaxial cable be run to the attic space and that the dipole antenna be mounted in the attic
space (if available) and connected to the coaxial cable using a female-to-female "barrel" F-connector. Alternatively
an omnidirectional or directional FM antenna (depending on location) may be necessary. Should an outdoor antenna
be necessary then it is important that it be installed properly by a qualified person(s). Outdoor antennas require
special safety precautions and proper grounding to prevent electrical shock and damage to the system from static
discharge and lightning. More information is available in the first section of this manual entitled,
INSTRUCTIONS.
Notes:
1. When installing an external antenna, pay attention to the antenna safety instructions in
"IMPORTANT SAFETY
AM / FM / CD / AUX / USB
AM ANT
INSTRUCTIONS"
Connecting FM Antenna
31
Secure the two leads of the 300-ohm FM dipole antenna
beneath the two screws of the black balun that was sup-
plied with the system. Connect the supplied FM antenna
balun onto the F-style 75-ohm FM antenna jack as shown
below. Extend the antenna within the wall if it was not
previously installed.
These should be the only antennas required for good AM &
FM radio reception. Should you live is a difficult reception
area or should the building's structure inhibit
good radio reception then an
external antenna can be
used. This is described
in the following sec-
tion.
