Unpacking and Setting UpYour HorizonTrio
Carefully unpack the HorizonTrio. If there is any sign of damage from transit, report it immediately to your dealer and/or
delivery service. Keep the shipping carton and packing materials for future use. Be sure to keep your purchase receipt in
asafe place,
as it may be required for warranty purposes.
In
the box you should find the Horizon Trio, the remote control and the power cord.
Placement
Your Horizon Trio will sound great just about anywhere. But if you
put it near awall or corner the bass response will be enhanced. Don't
block the bass port Be sure the vents on the top of the cabinet are
unobstructed to allow for ventilation.
Power Connection
Connect the power cord to the back of the Horizon Trio and plug it into
the wall power outlet.
AM and FM Antennas
The HorizonTrio comes out of the box ready to use. The internal AM
antenna
is connected.The FM antenna is also connected. Just extend
the wire connected to the plug.With the standard antennas you'll
probably pull in
more stations than any other radio you own. But if you
want to listen to stations that are very far away then external antennas
can be connected
to the antenna inputs.

About the Front Panel Controls
Most of the Horizon Trio functions are operated by the three controls on
the front panel.
PowerNolume - Is controlled by the large knob in the center of the
panel.
Mode -Selects the input you want to use or the function you want to
adjust.
Tune -Controls tuning the radio, changing CD tracks and various other
functions depending on the operating mode.
~ .. ,o Boston o
.... ,~,
.,
These logical, intuitive controls make it easy to operate the Horizon Trio.
The way you use each control is the same for each feature. Once you learn
how to control one of the features the rest of them will be easy. You may not need to refer to this manual once you
understand the way the controls work.
About the Remote Control
Most of the features of the Horizon Trio can be operated with the supplied remote control.
When it's
not being used, the remote control can be conveniently stored in the recess on top of
the Horizon Trio. The remote also has amagnetic backing so it can be attached to many metal
surfaces.
Note: When you unpack your remote control there will be aplastic insulation tab extending
from the battery compartment.
Pull out this tab before using the remote control.
There must be
an unobstructed line of sight to the front of the HorizonTrio when using the
remote control. Point the remote control at the front panel
of the Horizon Trio when pressing
the buttons.
For best results you should be within 20 feet of the unit and no more than 45° off axis.
