IDENTIFICATION OF CONTROLS

FRONT PANEL

1. STANDBY LED: This indicator will light up amber when the C 426 is in standby state. When the C 426 is at ON state, this indicator will illuminate blue. This indicator will extinguish itself when the power cable is unplugged from the AC supply.
2. STANDBY BUTTON: Press this button to turn ON the C 426. The Standby LED indicator will turn from amber to blue and illuminate the VFD. Pressing the STANDBY button again turns the unit back to standby mode.
3. FM/AM: Toggle [FM/AM] button to select AM or FM band.
4. FM MUTE/MODE: The front panel [FM MUTE/MODE] button is a dual-purpose control. In the normal position, "FM ST" and "FM MUTE" icons on the VFD are lit; only the stations with a strong signal can be listened to, and the noise between stations is muted.
   Pressing the [FM MUTE/MODE] button again ("FM ST" and "FM MUTE" icons on the VFD are extinguished) allows distant and potentially noisy stations to be received. Noise is reduced if the FM station signal level is less than the FM Stereo threshold (since mono FM is inherently less noise prone) though at the sacrifice of the stereo effect.
   The "FM MUTE" status can be stored for individual presets.
5. BLEND: The NAD BLEND feature will allow you to reduce the amount of noise and hiss but still retain some level of stereo separation, instead of mono. The [BLEND] button toggles between engaging and disengaging the BLEND feature. When engaged, "BLEND" is illuminated in the VFD; "BLEND" is extinguished when not engaged.
   The "BLEND" status can be stored for individual presets.
6. DISPLAY: Use this multifunction button to toggle between RDS PS, RDS RT and station frequency in FM tuner mode. Refer also to the item about VIEW RDS TEXT at the LISTENING TO AM/FM RADIO section of the OPERATION page.
   In combination with [MEMORY] button, [DISPLAY] button is also used in deleting stored presets. Refer also to the item about DELETE A PRESET at the LISTENING TO AM/FM RADIO section of the OPERATION page.
7. MEMORY: Press this button to store tuned AM or FM stations to the C 426's 40 preset-memory locations. One can store a mix of any AM or FM stations to the 40 available presets.
   In combination with [DISPLAY] button, [MEMORY] button is also used in deleting stored presets. Refer also to the item about DELETE A PRESET at the LISTENING TO AM/FM RADIO section of the OPERATION page.
8. PRESET/TUNE: Toggle [PRESET/TUNE] button to switch between "Preset" and "Tune" mode. Select TUNE mode ("TUNE" scrolls through the VFD) or PRESET mode ("PRESET" scrolls through the VFD).
9. REMOTE SENSOR: Point the TNR 1 remote control at the remote sensor and press the buttons. Do not expose the remote sensor of the C 426 to a strong light source such as direct sunlight or illumination. If you do so, you may not be able to operate C 426 with the remote control.

   Angle: About 30° in each direction of the front of the remote sensor
10. VACUUM FLUORESCENT DISPLAY (VFD): Provide visual information on the settings, conditions, status and other information relevant to the currently tuned station.
11. PRESET/TUNE CONTROL KNOB: The function of this control knob depends upon the selected tuning mode via the PRESET/TUNE button. Toggle [PRESET/TUNE] button to switch between "Preset" and "Tune" mode.
    1. Preset mode: Rotate the PRESET/TUNE control to the left to scroll to a lower Preset number; rotate the PRESET/TUNE control to the right to scroll to a higher Preset number. This is a "wrap-around" function – upon reaching the last stored Preset number, preset search will continue on with the first stored Preset number and vice-versa. Unused preset numbers are skipped over.
    2. Tune mode: Rotate the PRESET/TUNE control in either direction for more than 1 second to engage automatic tuning. The tuner will stop at the next sufficiently strong signal it encounters. Note that this function "wraps" – that is, it will continue to search from one end of the AM or FM band to the other until it stops at a strong signal. Rotate the PRESET/TUNE control again for more than 1 second to start searching again.

By briefly rotating the PRESET/TUNE control in either direction, manual tuning is engaged for precise tuning to a specific frequency. With each brief rotation, the tuner will take 0.05 MHz steps at FM band and 10 kHz (120V version) or 9 kHz (230V version) at AM band. When tuned accurately to a station, "TUNED" will be illuminated in the VFD. The antenna bars displayed below the ANTENNA icon in the VFD reflects the signal strength of the tuned station.

Automatic tuning is available on both AM and FM band.

OPERATION

LISTENING TO AM/FM RADIO

The C 426 offers very high quality sound from radio broadcasts. The reception and sound quality will always be dependent to a degree however on the type of antenna(s) used as well as proximity to the broadcast origin, geography and weather conditions.

ABOUT ANTENNAS

The supplied ribbon-wire FM antenna can be connected to the rear panel FM-antenna input using the included "balun" adapter and should be fully extended to form a "T". This folded-dipole antenna will usually work best when oriented vertically, with the arms of its "T" fully outstretched and arranged perpendicular to the origin of the desired broadcast. There are no "rules" however, and experimenting freely with antenna placement and orientation may yield the clearest sound and lowest background noise.

In areas of poor FM reception, an exterior FM antenna can improve performance dramatically. If radio listening is important to you, consider consulting an antenna installation professional to optimize your system.

The supplied AM "loop" antenna will usually provide adequate reception. However, an exterior AM antenna can be used to improve reception. Consult an antenna professional for more information.

ASSEMBLING THE LOOP ANTENNA
