CONTROL FUNCTIONS
(Numbers correspond with product diagram on page 13)
1. POWER – Switches the power (AC) on and off to the receiver.
2. INPUT SELECTOR – Changes the input source sequentially.
3. MUTE – When on, inter-station noises are muted while tuning the tuner.
4. STEREO – Switches the tuner from Mono to Stereo.
5. BW1 BANDWIDTH SETTING – When BW 1 is selected the tuner is in the “Wide”
IF Bandwidth setting. This setting produces the best sound where adjacent
channel interference is not a factor.
6. BW2 BANDWIDTH SETTING – When BW 2 is selected the tuner is in the
“Narrow Bandwidth” setting. This setting produces the best results where
adjacent channel interference is a factor.
7. SIGNAL STRENGTH/MULTIPATH METER – When the LED above the button is lit,
meter #11 will read the signal strength of the incoming signal, the higher the
better. The signal meter is calibrated so that it will never reach 10, this is done
to protect the meter mechanism. When the switch is set up to multi-path, meter
#11 will indicate the presence of multi-path. The unit should be tuned so that this
meter reads zero.
8. TUNING KNOB - Rotating this knob allows you to precisely tune to the frequency
of your choice. Slight detuning of the tuner may help eliminate multi-path or some
unusual atmospheric conditions that are affecting the sound of the tuner.
9. VOLUME CONTROL – The digitally controlled precision volume control allows you
to vary the volume from 0-99. Normal operating range is 40-85. Note that it is
not a linear volume control – therefore volume changes will vary more as you turn
the control at higher levels than at lower levels. The volume control has been
calibrated so that the volume level can not exceed the safe operating parameters
of the system
DISPLAY FUNCTIONS
10. FREQUENCY/VOLUME DISPLAY – Shows the tuned frequency from 87.5 MHz
thru to 108.5 MHz. This readout is controlled by the tuning control. Volume
control is between 0 – 99 controlled by the volume knob.
