Pressing the left tuning button will change the station frequency down the band. Pressing the right button
will change the station frequency up the band.
The Auto Selector controls whether the tuning buttons will change the station frequency by one channel
spacing (Manual Mode), or automatically move to the next usable station (Auto Mode). The status of
this mode is indicated in the display window by the logo “AUTO”.
In most situations, the Auto Mode is most useful, as it allows the tuner to increment automatically to the
next usable station, avoiding multiple button strokes to find a station.
However, the operation of the Auto
Mode is keyed to signal strength, so weak stations may be “missed” in the Auto Mode. Therefore, when
searching for a weak station, use Manual Mode.
The 945 has a total of 18 memory preset locations that may be used for storing and recalling either AM
of FM stations.
The Memory Preset buttons 1 through 9 access memory locations 1 through 9. Pressing the
+10
Shift
button simultaneously with a 1 through 9 button accesses memory locations 11 through 19. Note that
there is no memory 10.
The selected memory location is indicated in the display window underneath the “CH” logo.
The memory presets available from the front panel are also available from the Remote Control, but use
a different set of buttons.
The Next button may be used to increment the tuner to the next higher preset number. The ‘1’ or ‘11’
buttons may be used to “jump” from one group of preset numbers to another. This avoids having to press
the Next button repeatedly to access a distant preset number.
Example: The tuner is set to preset 4. To get to preset 13, press ‘1 1
',
then press Next twice.
To store a station into a memory location, first set the tuner to the desired broadcast station. Then press
the Memory button. A “MEMORY” logo will appear in the display for about four seconds. During this
period, press the desired preset button 1 through 9, or
+10
with 1 through 9. The station will now be
committed to that memory location.
Note that any station, AM or FM, may be stored in any location. The tuner will automatically switch
between AM and FM according to the station stored. It may be most convenient to store the stations
in numerical order, or to store them in descending order of most frequently used, or to use 1 through 9
for FM, and 11 through 19 for AM.
Storing stations into memory is not available from the Remote Control.
The 945 has the ability to detect FM stations broadcasting in stereo, and automatically switch on its
multiplex decoder. Stereo decoding is indicated by the logo “STEREO” visible in the display.
The background noise level of a stereo broadcast increases as signal strength decreases. The tuner
has the ability to detect low signal strength and automatically switch to mono to reduce this background
noise.
There are situations, particularly when a weak signal strength fluctuates, that it is best to force the tuner
into mono with the Mono Control. Mono Mode is active when the button is lighted green, as well as the
“STEREO” logo in the display being extinguished.
The Mono Control is not available from the Remote Control.
