PANEL DESCRIPTION

#7 PBT CLEAR SWITCH [PBT CLR] (p. 25)

Clears the PBT settings when pushed for 1 sec.

•The [PBT CLR] indicator lights when PBT is in use.

#8 NOTCH SWITCH [NOTCH] (p. 26)

➥ Switches the notch function between auto, man-

ual 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.

#9 PASSBAND TUNING CONTROLS [TWIN PBT]

Adjust the receiver’s “passband width” of the DSP

ﬁlter. (p. 25)

•Passband width and shift frequency are displayed in the

LCD.

•Push [PBT CLR] for 1 sec. to clear the settings when not

in use.

•Variable range is set to 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.

$0 LOCK INDICATOR [LOCK] (p. 46)

Lights when the dial lock function is activated.

$1 MEMO PAD-READ SWITCH [MP-R] (p. 56)

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)

$2 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. 23)

•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. 23, 51)

•e.g. to enter 14.195 MHz, push [F-INP] [1] [4] [•] [1]

[9] [5] [(F-INP)ENT].

$3 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 1 sec. (Quick dualwatch function)

•The quick dualwatch function can be turned OFF

using set mode. (p. 69)

$4 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 1 sec. in non-FM modes. (Quick split function)

•The offset frequency is shifted from the main readout

frequency in FM mode. (pgs. 47, 69)

•The quick split function can be turned OFF using set

mode. (p. 69)

➥ Turns the split function ON and shifts the sub

readout frequency after inputting an offset

(±4 MHz in 1 kHz steps).

$5 MEMO PAD-WRITE SWITCH [MP-W] (p. 56)

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)

$6 RECEIVE INDICATOR [RX]

Lights green while receiving a signal and when the

squelch is open.

$7 TRANSMIT INDICATOR [TX]

Lights red while transmitting.
