Q.
How do I know if I'm receiving an HD digital radio signal?
A. If you are tuned to a radio station broadcasting an HD signal, the “DIGITAL’ light on the front of
the receiver will be lit.
Q.
Why doesn’t the HD Radio signal come up right away?
A. It takes a few seconds for the receiver to find and convert the HD digital signal, which is normal.
During this time you will hear an analog signal if it’s available. Once the digital signal is converted,
the receiver will “blend” the two signals as it switches to digital.
Q.
Why can’t I receive an HD signal on an AM station at night?
A. The Federal Communications Commission (FCC), which regulates US radio transmissions, pro-
hibits AM radio stations from transmitting in HD digital after sunset. This is due to the greater dist-
ances AM signals can travel at night. At night, a strong HD signal from one location could interfere
with distant stations on a similar frequency. Some AM stations are required to reduce the power of
their analog signal at night for the same reason.
Q.
Why is the informtion stream scrolling across the LCD display wrong or incomplete?
A. The text is made available by each radio station. Contact your local station with any questions
regarding the content of their text stream.
Q.
Why is there no sound (or the sound cuts out)?
A. First, check the volume. Make sure there are no headphones plugged into the receiver. Using the
HEADPHONE connection prevents sound from playing through the speakers. Check to make sure
all cables are connected to the back of the receiver.
Q.
I have connected the external antenna. Why hasn’t the reception improved?
A. When using an AM antenna, be sure the + and - are connected to the proper posts. Next, try re-
adjusting the antenna by a quarter-turn to see if the reception improves. When using an FM dipole
antenna, be sure both “arms” are fully extended to form a T. Try adjusting the antenna a quarter-
turn to see if the reception improves. If reception still hasn’t improved, you may have a source of
interference nearby. For more information on improving reception, visit our online support center
at www.radiosophy.com/help.
Q.
How do I connect to cable TV radio signals?
A. Some cable companies do provide an FM radio signal (Contact your cable provider for assist-
ance). To connect your radio to a cable FM signal, you must use an FM signal splitter. Connect
their coaxial cable to the 75 ohm FM antenna connector on the back of the HD100. This connection
is easier if you obtain a screw-on or push-on RF adapter (available at electronic stores).
