FRONT PANEL CONTROLS
1 Power On/Off - POWER switches the tuner on or off. Pressing the
Power switch turns the Tuner on, the Display Panel and Power Status
Indicator (No. 2) will light up. Pressing the Power button again will
switch the unit off.
NOTE
The C 422 has a receiver for remote control commands built-in. Most
NAD system remote control handsets with an On/Off toggle button
or separate On and Off button will be able to switch the tuner from
On to Stand-by and vice-versa.
The C 422 uses a memory back-up system to store Preset
information. This information is retained for several weeks, even if
the unit is switched off completely or unplugged. When switching
power On, the C 422 will go back to the station last tuned to before
the unit was turned off. This will allow you to make timer recordings
using an external timer and recorder.
2 Power Status Indicator - The Power Status Indicator will light up
green when Power is on. When the tuner is switched to Stand-by
mode (through either a remote control or the 12V trigger input) the
indicator will light up amber. When the unit is switched off
completely, it is off.
3 Blend - Weak or remote stereo radio stations are sometimes
received with noise and hiss as the antenna signal is too weak. By
switching the tuner to mono will reduce the amount of noise and
hiss but at the expense of any stereo information. The NAD Blend
feature will allow you to reduce the amount noise and hiss but still
retain some level of stereo separation, instead of mono. The Blend
button toggles between engaging or disengaging the Blend feature;
when engaged, "BLEND" lights up in the display.
NOTE
The "Blend" status can be stored for individual presets. Refer to the
separate chapter "Storing, Recalling and Labelling Presets" for more
information.
4 Memory - The Memory is used to store stations into the Preset
Memory bank and to store user defined names for non-RDS Preset
stations. When Memory is pressed during normal operation, the
Preset number and the red "MEMORY" indicator will flash in the
Display Panel. If no other buttons are pressed within 12 seconds, the
tuner will revert to its previous state. Refer to the separate chapter
"Storing, Recalling and Labelling Presets" for more information.

5 FM Mute/Mode - This button combines two functions; it switches
the tuner from Stereo to Mono and disengages the muting circuitry
at the same time. The muting circuit will mute the tuner in between
radio stations when searching or tuning. This way the tuning noise is
avoided. The muting circuit however may suppress very weak radio
station signals. If a 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 will allow
the station to be heard and will cancel most or all of this background
noise.
In normal operation the mute circuit is engaged, the display indicates
"FM MUTE". Press the FM Mute/Mode button to disengage the
muting circuit and switch from stereo to mono reception. "FM
MUTE" in the display will extinguish. Press the FM Mute/Mode switch
again to return to Auto Stereo FM operation.
NOTE
The "FM Mute/Mode" status can be stored for individual presets.
Refer to the separate chapter "Storing, Recalling and Labelling
Presets" for more information.
6 AM/FM - The AM/FM button switches the tuner from the AM band
to the FM band and vice-versa. The Display Panel shows the
frequency of the tuned station and which band is selected. The FM
tuning is in 0.05 MHz increments, AM tuning is in 9 kHz or 10 kHz
increments, depending on the version.
7 Display - With stations carrying RDS information, The Display
button scrolls between three different display modes, each successive
push of the button engages the next one of the three modes:
a) In the default mode, the station's RDS name is displayed, Program
Service (PS; normally the station's calling letters, BBC R3, for
instance).
b) From the default mode, press the button once to view Radio Text
(RT). This can be additional information such as the presenter's or
program's name; what song is playing, etc. This text scrolls
continuously over the 8 alphanumeric display segments.
c) Press the button from the display RT mode to display the station
frequency. Press again to return to the default mode (a).
When tuned to a non-RDS station - The Display button toggles
the display to show either the station frequency or user entered
station name. If no user name was entered the display will indicate
"NO RDS". The Display button is also used to label non-RDS stations
with a name. Refer to the separate chapter "Storing, Recalling and
Labelling Presets" for more information.
