RIT/SUB DIAL SWITCH [RIT/SUB]
(pgs. 21, 47)
➥
Push to toggle the RIT or SUB DIAL function ON
and OFF—initial set mode is used to select the
desired action*.
• Lights green when the SUB DIAL function is ON; lights
red when the RIT function is ON.
• Use the [M-CH] control to vary the RIT frequency or
SUB DIAL frequency (see below).
➥
When the RIT function is ON, push for 1 sec. to
add or subtract the shifted frequency to the oper-
ating frequency.
*Even if RIT is selected in initial set mode, RIT cannot be se-
lected when operating AM or FM modes.
✔
What is the RIT function?
The RIT (Receiver Incremental Tuning) shifts the receive fre-
quency without shifting the transmit frequency.
This is useful for fine tuning stations calling you on an off-fre-
quency or when you prefer to listen to slightly different-
sounding voice characteristics, etc.
!7
SHIFT CONTROL [SHIFT]
(outer control; p. 47)
Shifts the center frequency of the receiver’s IF pass-
band.
• Rotate the control clockwise to shift the center frequency
higher, or rotate the control counterclockwise to shift the
center frequency lower.
• When rotate the control, the IF passband is graphically
displayed and changes in accordance with the [SHIFT]
control.
!8
M-CH CONTROL [M-CH]
(inner control)
➥
When the RIT or SUB DIAL functions are OFF, ro-
tate to select a memory channel number (p. 56).
➥
Shifts the receive frequency while the RIT func-
tion is ON in SSB, CW and RTTY modes (see
above or p. 47).
• RIT variable range is ± 9.99 kHz
➥
Changes the operating frequency in the selected
tuning steps while the SUB DIAL function is ON
(p. 21).
!9
HEADPHONE JACK [PHONES]
(p. 14)
Accepts headphones with 8–16
Ω
impedance.
• When headphones are connected, no receive audio
comes from the speaker.
• When the PHONES/SPEAKER switch on the back of the
front panel is set to the [SPEAKER] position, an external
speaker can be connected. This is convenient for mobile
or outdoor operation.
@0
TUNER SWITCH [TUNER]
(pgs. 64–66)
➥
Push momentarily to toggle the automatic an-
tenna tuner function ON and OFF (bypass).
• Lights red when the automatic antenna function is ON.
➥
Push this switch for 1 sec. to manually tune the
antenna.
• When the tuner cannot tune the antenna, the tuning
circuit is bypassed automatically after 20 sec.
@1
FRONT PANEL LATCH
(p. 12)
Pull away from the transceiver (towards yourself
when looking at the front of the transceiver) to de-
tach the front panel from the main body of the trans-
ceiver.
@2
PRE AMP/ATTENUATOR SWITCH [P.AMP/ATT]
(p. 46)
➥
Push momentarily to turn the preamp ON or OFF.
➥
Push for 1 sec. to turn the 20 dB attenuator ON;
push momentarily to turn the attenuator OFF.
• Lights green when the preamp is ON; lights red when the
20 dB attenuator is ON.
✔
What is the preamp?
The preamp amplifies received signals in the front end cir-
cuit to improve the S/N ratio and sensitivity. Turn ON ‘P.AMP’
when receiving weak signals.
✔
What is the attenuator?
The attenuator prevents a desired signal from distorting
when very strong signals are near the desired frequency, or
when very strong electric fields, such as from a broadcast-
ing station, are near your location.
P.AMP/ATT
Lights green while the preamp is activated;
lights red while the attenuator is activated.
TUNER
Lights while the automatic
tuning function is activated.
