The following steps show you how to tune in to FM and 
AM radio broadcasts using the automatic (search) and 
manual (step) tuning functions. If you already know the 
frequency of the station you want, see Tuning directly to a 
station below. Once you are tuned to a station you can 
memorize the frequency for recall later—see Saving 
station presets below for more on how to do this.

 

 

necessary.
Each press switches the band between FM and AM.

There are three ways to do this:

Automatic tuning – To search for stations in the 
currently selected band, press and hold TUNE 

/ 

for about a second. The receiver will start searching 
for the next station, stopping when it has found one. 
Repeat to search for other stations.

Manual tuning – To change the frequency one step 
at a time, press TUNE 

/.

High speed tuning – Press and hold TUNE 

/ for 

high speed tuning. Release the button at the 
frequency you want.

If the TUNED or STEREO indicator doesn’t light when 
tuning to an FM station because the signal is weak, press 
MPX to switch the receiver into mono reception mode. 
This should improve the sound quality and allow you to 
enjoy the broadcast.

This feature uses Neural Surround™, THX

®

 technologies 

to achieve optimal surround sound from FM radio.

• While listening to FM radio, press AUTO/ALC/

DIRECT for Neural THX listening.

See About Neural – THX Surround on page 110 for more 
on this.

The Neural THX mode can be selected also with 
STANDARD.

Sometimes, you’ll already know the frequency of the 
station you want to listen to. In this case, you can simply 
enter the frequency directly using the number buttons on 
the remote control.

necessary.
Each press switches the band between FM and AM.

the radio station.
For example, to tune to 106.00 (FM), press 1, 0, 6, 0, 0.

If you make a mistake halfway through, press D.ACCESS 
twice to cancel the frequency and start over.

If you often listen to a particular radio station, it’s 
convenient to have the receiver store the frequency for 
easy recall whenever you want to listen to that station. 
This saves the effort of manually tuning in each time. This 
receiver can memorize up to 63 stations, stored in seven 
banks, or classes (A to G) of 9 stations each. When saving 
an FM frequency, the MPX setting (see above) is also 
stored.

See Listening to the radio above for more on this.

The display shows PRESET MEMORY, then a blinking 
memory class.

/ to select the station preset you 

want.
You can also use the number buttons to select a station 
preset.

After pressing ENTER, the preset class and number stop 
blinking and the receiver stores the station. 

For easier identification, you can name your station 
presets. 

See Listening to station presets below for how to do this.

The display shows PRESET NAME, then a blinking cursor 
at the first character position.
