4. SEARCH/PRESET
The Search/Preset button scrolls between three different tuning modes, each successive push of the button engages the next one of the three 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” lights up in the display.
b)Search mode: By pressing the Tune/Preset button (10) 
or
you can 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 Tune/Preset button again to start searching again. “SEARCH” lights up in the display. If a stereo station is received “STEREO” will light up in red in the display, unless FM Mute/Mode (No. 7) was engaged.
c) Tune mode: By pressing the Tune/Preset button (No. 10)
or | you can engage manual tuning respectively up or down |
the frequency band for precise tuning to a specific frequency. Keep either one of the Tune/Preset buttons pressed until you
are in the proximity of the desired frequency (use the | to | |
tune upwards in frequency; | for downwards tuning). With | |
each successive tap of the keys, the tuner will take 0.025MHz steps on FM so you can accurately tune into the desired frequency. For AM the tuning steps can be 9 kHz or 10 kHz, depending on the version of your C440. This tuning mode can also be useful when trying to receive a radio station which is too weak for the Search mode. When tuned accurately to a station, “>TUNED<” will light up in the display.
NOTE: The Search/Preset buttons are also used in conjunction with the Memory (No. 6) and Tune/Search (No. 10) buttons to add and memorise user defined names to Presets. Refer to the separate chapter “Storing, recalling and naming Presets” for more information.
5. 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.
6. MEMORY
The Memory is used to store stations into the three Preset Memory banks or to store user defined names for
Note: The 120V versions (North America) do not have RDS (Radio Data System).
7. 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.
Very weak radio station signals however may be suppressed by the muting circuit. 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 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.
8. PS/RT (ON RDS VERSIONS ONLY)
With stations carrying RDS information, The PS/RT 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. It takes a few seconds for the tuner to gather the RT information, so immediately after tuning to a station and selecting to view RT the display will indicate “WAIT” and default to the station name.
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 GB entered the display will just flash once.
NOTE: The 120V versions (North America) do not have RDS (Radio Data System)
8.DISPLAY (ON NON-RDS VERSIONS ONLY)
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 just flash once.
9.CHARACTER
The Character Button is used to enter the names of Preset radio stations for display when the station is selected. Used together with the Tune/Preset (No. 10) and MEMORY (No. 6) Buttons. Refer to the separate chapter “Storing, recalling and naming Presets” for more information.
