Unpacking and Setting Up Your Horizon Duo  
Carefully unpack the Horizon Duo. 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 a safe place, as it may be required for warranty purposes.  
In the box you should find the Horizon Duo, the remote control and the power cord.  
Placement  
Your Horizon Duo will sound great just about anywhere.  
FM Antenna Input  
AM Antenna Input  
iPod Dock Input  
But if you put it near a wall 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  
Just connect the power cord to the back of the Horizon  
Duo and plug it into the wall power outlet.

AM and FM Antennas  
The Horizon Duo 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 Duo functions are operated by the three  
controls on the front panel.  
Power/Volume – 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 – Tunes in a new radio station.  
These logical, intuitive controls make it easy to operate the Horizon  
Duo. The way you use each contol 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 Duo 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 Duo. The remote also  
has a magnetic backing so it can be attached to many metal surfaces.  
Note: When you unpack your remote control there will be a plastic 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 Horizon Duo  
when using the remote control. Point the remote control at the front panel of  
the Horizon Duo when pressing the buttons. For best results you should be  
within 20 feet of the unit and no more than 45° off axis.  
Note: Eventually you’ll need to replace the remote battery. If the remote doesn’t reliably operate the Duo, put  
in a new CR2025 3V lithium coin type battery.
