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

Rotate the outer frame of the antenna.

Insert the bottom edge of the outer frame into the groove on the stand.

Extend the antenna cord.

SELECTING A TUNER BAND

Toggle front panel’s [FM/AM] button to select either AM or FM band. Using 
the TNR 1, select desired band by directly pressing [AM] or [FM] button.

TUNING STATIONS

Toggle front panel’s [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).

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. 

DIRECT TUNING

If you know your desired station’s frequency allocation, you can tune 
directly to the station. 

Toggle front panel’s [PRESET/TUNE] button to switch between “Preset” 
and “Tune” mode. Select TUNE mode (“TUNE” scrolls through the VFD).

Using the numeric keys of the remote control, key-in the frequency 
allocation of the station. For example, to enter 104.50MHz, press “1”, “0”, 
“4”, “5” and “0” or press “1”, “0”, “4” and “5”. 

STORING PRESETS

The C 426 can store a mix of your 40 favorite AM and FM stations for 
immediate recall.

To store a Preset, tune first to the desired frequency and then press the 
front panel [MEMORY] button.

“MEMORY” and the next available Preset number will continually flash 
on the VFD (If all 40 preset numbers are allocated already, you can 
overwrite an existing Preset number. Rotate the PRESET/TUNE control 
knob to select the Preset number you want to overwrite). 

Press the [MEMORY] button again to store the desired frequency on the 
Preset number shown (“STORED” scrolls through the VFD). Your desired 
frequency is now stored in the assigned preset.

DIRECT RECALL OF A PRESET

You can directly recall a desired Preset number. 

Toggle front panel’s [PRESET/TUNE] button to switch between “Preset” 
and “Tune” mode. Select PRESET mode (“PRESET” scrolls through the 
VFD).

Using the numeric keys of the remote control, key-in directly your 
desired Preset number. 

DELETE A PRESET

Select the Preset number to be deleted.

Press and hold both the front panel [MEMORY] and [DISPLAY] buttons 
until “DELETE” is shown flashing in the VFD. Immediately release both 
buttons and then press [DISPLAY] button again (“DELETED” scrolls 
through the VFD). Current Preset number is now deleted.

ABOUT USER NAMES

A particular Preset number can be assigned an eight-character “User Name”. 
This applies only to stored AM stations and non-RDS FM stations. The 
assigned “User Name” will be shown in the VFD whenever the associated 
Preset number is recalled.

ENTERING USER NAMES

To assign a Preset number with the user name “NEWS”, follow the procedure 
as below. 

Recall the desired Preset number.

Press and hold [DISPLAY] button until the display shows a flashing 
cursor point. 

Rotate the [PRESET/TUNE] control knob to select the first character of 
the name (“N” from the alphabetical list).

Press [DISPLAY] button to select the character and correspondingly 
move forward to the next position. Repeat this process for each 
character in sequence. 

Press the [MEMORY] button to store the User Name (“STORED” scrolls 
through the VFD). The current Preset number is now assigned the user 
name “NEWS”.
