PANEL DESCRIPTION
#5 PBT CLEAR SWITCH [PBT CLR] (p. 26)
Clears the PBT settings when pushed for 2 sec.
•The [PBT CLR] indicator appears when PBT is in use.
#6 NOTCH SWITCH [NOTCH] (p. 27)
➥Toggles the notch function between auto, manual
and OFF in SSB and AM modes.
➥Turns the manual notch function ON and OFF
when pushed in CW mode.
➥Turns the auto notch function ON and OFF when
pushed in FM mode.
•“AN” appears when auto notch is in use.
•“MN” appears when manual notch is in use.
✔
What is the notch function?
The notch function eliminates unwanted CW or AM carrier
tones while preserving the desired signal’s audio response.
The filtering frequency is adjusted to effectively eliminate un-
wanted tones via the DSP circuit.
#7 PASSBAND TUNING CONTROLS [TWIN PBT]
Adjust the receiver’s “passband width” of the DSP
filter. (p. 26)
•Passband width and shift frequency are displayed in the
LCD.
•Push [PBT CLR] for 2 sec. to clear the settings when not
in use.
•Variable range is set to the half of the IF filter passband
width. 25 Hz steps and 50 Hz steps are available.
•These controls function as an IF shift control while in AM
mode and when the RTTY filter is turned ON. Only the
inner control may function in this case.
✔
What is the PBT control?
General PBT function electronically narrows the IF passband
width to reject interference. This transceiver uses the DSP
circuit for the PBT function.
#8 LOCK INDICATOR [LOCK] (p. 45)
Lights when the dial lock function is activated.
#9 MEMO PAD-READ SWITCH [MP-R] (p. 55)
Each push calls up a frequency and operating
mode in a memo pad. The 5 (or 10) most recently
programmed frequencies and operating modes can
be recalled, starting from the most recent.
•The memo pad capacity can be expanded from 5 to 10
in set mode for your convenience. (p. 71)
$0 KEYPAD
➥Pushing a key selects the operating band.
•[GENE] selects the general coverage band.
➥Pushing the same key 2 or 3 times calls up other
stacked frequencies in the band. (p. 24)
•Icom’s triple band stacking register memorizes 3 fre-
quencies in each band.
➥After pushing [F-INP], enters a keyed frequency
or memory channel. Pushing [(F-INP)ENT] or
[Y]/[Z] is necessary at the end. (pgs. 24, 50)
•e.g. to enter 14.195 MHz, push [F-INP] [1] [4] [•] [1]
[9] [5] [(F-INP)ENT].
$1 MEMO PAD-WRITE SWITCH [MP-W] (p. 55)
Programs the selected readout frequency and op-
erating mode into a memo pad.
•The 5 most recent entries remain in memo pads.
•The transmit frequency is programmed when pushed to-
gether with [XFC].
•The memo pad capacity can be expanded from 5 to 10
in set mode for your convenience. (p. 71)
$2 DUALWATCH SWITCH [DUALWATCH] (p. 31)
➥Turns the dualwatch function ON and OFF when
pushed.
➥Turns the dualwatch function ON and equalizes
the sub readout frequency to the main readout
when pushed for 2 sec. (Quick dualwatch func-
tion)
•The quick dualwatch function can be turned OFF
using set mode. (p. 68)
$3 SPLIT SWITCH [SPLIT] (p. 32)
➥Turns the split function ON and OFF when
pushed.
➥Turns the split function ON, equalizes the sub
readout frequency to the main readout and sets
the sub readout for frequency input when pushed
for 2 sec. in non-FM modes. (Quick split function)
•The offset frequency is shifted from the main readout
frequency in FM mode. (pgs. 46, 69)
•The quick split function can be turned OFF using set
mode. (p. 68)
➥Turns the split function ON and shifts the sub
readout frequency after inputting an offset (±4
MHz in 1 kHz steps).
$4 RECEIVE INDICATOR [RX]
Lights green while receiving a signal and when the
squelch is open.
$5 TRANSMIT INDICATOR [TX]
Lights red while transmitting.
