PANEL DESCRIPTION
!6 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.
