. _ RECEIVER OPERATION eB
Operate your National Panasonic RF-2800LBS/LBE radio receiver
as you would with any ordinary radio. To obtain the best per-
formance and take advantage of some of the high-performance
features of the receiver, keep in mind the following operating
hints.
FM Reception:

Radio/Phono Selector® ............ RADIO
Band Selector@ ..........ccceeeee FM AFC
Digital Display Switch® ............ ON (only during tuning)
Tuning Control® .........cceeeee Desired station
Volume Controi@ —.......eeeeeee eee Desired level

Note: Changing the receiver's direction may improve reception
as the built-in AM ferrite core antenna is somewhat direc-
tional.
SW Reception:

To correct a frequency display error:
1) Tune to any SW station whose frequency is known, and make
sure the frequency tallies with the display (the selected
station will be detuned if there is an error in the Digital
Frequency Counter@).
2) Slowly move the SW Calibrator@, watching the Tuning
Indicator@, for best reception. When the meter pointer de-
flects to the extreme left, optimum reception is achieved and
the error will be corrected.
Note: + At the "STD" positions on the Tuning Dial@, the 5, 10,
and 15 MHz standard frequency signals will be received,
and those signals may be used for error correction.
«If the Tuning Indicator@ pointer exceeds full scale be-
cause the signals are too strong, decrease the receiver
sensitivity to the optimum tuning readout level by turn-
ing the RF Gain Control counterclockwise.
SSB and CW Reception:
Set the receiver up in the same manner as for SW Reception, and
then:
H Set the BFO Switch@ to ON.
™ Tune to the desired signal.
™@ Carefully move the BFO Pitch Control@® back and forth until
the signal becomes most understandable.
Note: In receiving two-way communication signals, a possible
difference between the two frequencies may require
another BFO Pitch Control adjustment.
To reduce interference:
M™@ Set the Bandwidth Switch@® to NARROW (down), and retune.
@ Turn the RF Gain Control@ counterclockwise until the inter-
ference fades away, and readjust the Volume Control@.
M™ Turn the receiver in the direction which offers minimum inter-
ference.
To decrease background noise:
W@ Perform external antenna and ground connections.
M™@ Lower the treble tone by turning the Treble Control@® counter-
clockwise.
M Push the Digital Display Switch@® to OFF to eliminate the
frequency counter noise or beat note.
Note:
* Allow about 30-minute warmup for absolutely exact and stable
frequency display.
* Turning the Digital Display Switch@® on and off may slightly
shift the tuned frequency.
