10. PRESET/TUNE AND
The function of these buttons depends on the tuning mode
selected with the Preset/Tune button (No. 8). The Preset button
toggles between the two operation modes:
a) Preset mode (indicated in the display area): Press the
(down) button to scroll to a lower number Preset; press the
(up) button 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 when tuning either up or down.
b) Tune mode: Press the (down) or (up) button 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. Press the Down/Up button again for 1
second to start searching again.
By briefly tapping the (down) or (up) buttons you can
engage manual tuning respectively up or down the frequency band
for precise tuning to a specific frequency. With each successive tap
of the keys, the tuner will take 0.1 MHz steps (120V version) or
0.05 MHz steps (230V version) 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).
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/MONO
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
C420, have Preset Up and Down functions. Even if the C420 is in
Tune Mode, these remote control’s Preset Up and Down buttons
will only change presets. The Preset/Tune
and buttons
are also 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.
STORING, RECALLING AND LABELLING
PRESETS
Up to 30 presets in total can be stored in the C420’s memory bank;
these can be any mix of either AM or FM stations. When scrolling
through the presets, empty preset places will be skipped; it is thus
possible to go from preset No. 4 to No. 7 without having seen No.
5 and 6. With the presets you can also store whether you want
Blend (No. 3) and FM Mute/Mode (No. 5) to be activated as well
every time you recall the preset.
TO STORE A PRESET
• Tune to the radio station you wish to enter into a Preset (refer
to this chapter’s section 10). If the station is transmitting RDS
information, the RDS indicator will light up and station initials
or name will be shown in the Display Panel. If a non-RDS
station is found, then just the frequency will be shown.
• Select Blend (No. 3) or FM Mute/Mode (No. 5) if desired.
• To store that station as a Preset, press Memory (No. 4). The
Preset number and the red “MEMORY” indicator are flashing
in the Display Panel. The lowest available empty preset number
will be shown. If no other buttons are pressed within 12
seconds, the tuner will revert to its previous state.
• Press Memory again to store the preset. If you wish to assign a
different preset number, press either the Preset/Tune or
button to select the desired preset number. You can over-
write an existing preset. If the preset number already has been
assigned, “MEMORY” will stop blinking, but the preset will
continue to blink. When you have selected the desired preset
number, press Memory again to store the station.
NOTES:
You can enter a new station into an unused Preset or
over-write an existing programmed Memory Preset. By doing this
you will replace all the data previously held on that Preset number.
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. The Memory Presets have a memory
back-up, so they will remain stored for several weeks even if the
Tuner is switched off or unplugged from the mains supply.
RECALLING A PRESET
• To select a Preset station, check if Preset mode is engaged (the
display indicates “PRESET”). If not, press the Preset/Tune
Mode button (No. 8); “PRESET” will now light up in the
display.
• Press either the Tune/Preset or buttons (No. 10)
until the right Preset is found and shown in the Display Panel.
Any unused Presets will be skipped; this avoids having to scroll
through empty presets.
DELETING A STORED PRESET
You can empty a Preset by deleting the stored information:
• Select the Preset to be emptied.
• Press and hold the Memory button (No. 4) and Display button
(No.7) for two seconds. The preset number and the text
“DELETE” will flash in the display.
• Press only the display button again (within default time of 5
seconds) to confirm you want to delete this preset. The text
“DELETED” and “—” as the Preset number appear in the
display for a couple of seconds.
