8 Preset/Tune - The Search/Preset button toggles between two
different modes:
a) Preset mode: In this mode you can use the Tune/Preset button
(No. 10) to select a Preset. When Preset Mode is selected
"PRESET" will scroll once through the display and the PRESET
indicator lights up in the display.
b) Tune mode: By rotating the Preset/Tune control (10)
you can engage automatic or manual tuning respectively
down or up the frequency band. When Tune mode is selected,
"TUNE" will scroll through the display once.
9 Display Area - The display area gives all vital information on the
status of the tuner.
Displayed are:
• Band and frequency of current station, RDS PS (station name), or
RDS Radio Text. The latter two only if RDS is available; select using
the Display button (No. 7).
• If an FM Stereo broadcast is received.
• If the FM station also broadcasts RDS.
• If "Memory" has been engaged
• Preset number if the current station is stored in the tuner's
memory bank.
• If Blend and FM Mute/Mode are switched On.
• Radio Signal Strength. The bars just below "ANTENNA" indicate
the radio station's signal strength. The more bars are lit, the
stronger the station.
NOTE
The infrared sensor, which receives commands from a remote control
(not supplied), is located on the left side of the display window. There
must be a clear line-of-sight path from the remote control to this
window; if that path is obstructed, the remote control may not work.
10 Preset/Tune Control - The function of this control depends on the
tuning mode selected with the Preset/Tune button (No. 8). The
PRESET/TUNE Control operates when the rotational switches are
engaged; either clockwise or counter clockwise, and the contact
switches are engaged. The Preset/Tune button toggles between the
two operational modes:
a) Preset mode (indicated in the display area): Rotate the
Preset/Tune control to the left to scroll to a lower number Preset;
rotate the Preset/Tune control to the right to scroll to a higher
Preset number. This is a "wrap-around" function, so that going
from the highest number Preset, the tuner will go to the lowest
Preset number or vice-versa either up or down when tuning.
b) Tune mode: Rotate the Preset/Tune control in either direction
for more than 1 second to engage automatic tuning respectively
up or down the frequency band. The tuner will search
automatically for the first reasonably strong radio station, where
it will stop. Rotate the Preset/Tune control again for 1 second to
start searching again.
By briefly rotating the Preset/Tune control in either direction you will
engage manual tuning respectively up or down the frequency band
for precise tuning to a specific frequency. With each brief rotation,
the tuner will take 0.05 MHz steps on FM so you can accurately tune
into the desired frequency. For AM the tuning steps are set at 10 kHz
(120V version) or 9 kHz (230V version).
or
This tuning mode can also be useful when trying to receive a radio
station, which is too weak for the auto search mode. When tuned
accurately to a station, "TUNED" will light up in the display. The
muting circuit however may suppress very weak radio station signals.
If such a very weak station is in stereo it will have a high level of
background hiss. Switching to Mono Mode and disengaging the
muting circuit by depressing the FM MUTE/MODE button (No. 5) will
allow the station to be heard and will cancel most or all of this
background noise.
NOTES
Automatic tuning is available on both FM and AM.
Some NAD system remote controls, compatible with the NAD C 422,
have Preset Up and Down functions. Even if the C 422 is in Tune
Mode, this remote control's Preset Up and Down buttons will only
change presets. The Preset/Tune
used in conjunction with the Memory (No. 4) and Display (No. 7)
buttons to add and memorise user defined names to Presets. Refer
to the separate chapter "Storing, recalling and naming Presets" for
more information.
