8 Preset/Tune - The PRESET/TUNE button toggles between two
different modes:
a) Preset mode: In this mode you can use the PRESET/TUNE
Control (No. 10) or
Mode is selected "PRESET" will scroll once through the display
and the PRESET indicator lights up in the display.
b) Tune mode: By rotating the PRESET/TUNE Control (No. 10)
or you can engage automatic or manual tuning
respectively down or up the frequency band. When Tune mode
is selected, "TUNE" will scroll through the display once.
9 Display Area - The display area gives all vital information on the
status of the tuner.
Displayed are:
• Band and frequency of current station, RDS PS (station name), or
RDS Radio Text. The latter two only if RDS is available; select using
the Display button (No. 7).
• If an FM Stereo broadcast is received.
• If the FM station also broadcasts RDS.
• If "Memory" has been engaged
• Preset number if the current station is stored in the tuner's
memory bank.
• If Blend and FM Mute/Mode are switched On.
• Radio Signal Strength. The bars just below "ANTENNA" indicate
the radio station's signal strength. The more bars are lit, the
stronger the station.
NOTE
The infrared sensor, which receives commands from a remote control
is located on the left side of the display window. There must be a
clear line-of-sight path from the remote control to this window; if
that path is obstructed, the remote control may not work.
10 Preset/Tune Control (TNR 1 Figure 3)- The function of this
control depends on the tuning mode selected with the PRESET/TUNE
button (No. 8). The PRESET/TUNE (No. 8) button toggles between the
two operational modes:
a) Preset mode (indicated in the display area): Rotate the
PRESET/TUNE Control to the left to scroll to a lower number
Preset; rotate the PRESET/TUNE Control to the right 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 either up or down when
tuning.
b) Tune mode: Rotate the PRESET/TUNE Control in either direction
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. Rotate the PRESET/TUNE Control again for 1 second
to start searching again.
to select a Preset. When Preset
By briefly rotating the PRESET/TUNE Control in either direction you
will engage manual tuning respectively up or down the frequency
band for precise tuning to a specific frequency. With each brief
rotation, the tuner will take 0.05 MHz steps 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/MODE 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.

memorise user defined names to Presets. Refer to the separate
chapter "Storing, recalling and labelling Presets" for more
information.
11 Sleep Mode (TNR 1 Figure 3) - The Sleep Mode timer will switch
the C425 to Standby mode automatically after a preset number of
minutes. Pressing the TNR 1's SLEEP button once will display the
setting of the sleep time increment. Pressing the TNR 1's SLEEP
button a second time within a 3-second period will change the sleep
time increment in 30-minute intervals, after which time the C425 will
automatically switch into Standby mode. To adjust the sleep delay,
press the TNR 1's SLEEP button twice; first to display the sleep time
increment, and a second time to change the sleep time increment.
Each consecutive press increases the sleep time in 30-minute
increments from 30 to 90 minutes. To cancel the sleep mode,
continue pressing the TNR 1's SLEEP button until "OFF" displays.
Switching the C425 to standby from either the TNR 1's OFF or the
C425's Power button will also cancel the sleep mode
12 Dimmer (TNR 1 Figure 3) - The brightness of the C425's VFD
can be adjusted to match your room's ambient lighting. Press this
button once for 1/2 VFD brightness, a second time for completely
darkening the VFD, and then a third time to bring the VFD back to
full brightness. The brightness will revert to full brightness when
power is cycled.
