Clock
Indicates the current time.
To set the clock:
1. Press and hold the [ C.S ] button until the clock
digits blink.
2. Enter the present time via the number keys
[ BAND ]
( keys).
3. Press the [ ENT ] button.
Multi-Function Display
This area usually displays the status of major func-
tions.
Press the [ /// ] buttons to select an indicator
for the desired function, then press the [ SELECT ]
button to select either of the settings.

This area also shows the CW/RTTY/DATA texts,

SCOPE level meters, memory channels, and
menu items.
VOX:
This is the ON or OFF indicator for the automatic
voice-actuated transmitter switching in the SSB,
AM, and FM modes. The controls affecting VOX
operation are the Menu items "181 VOX GAIN",
"182 VOX DELAY", and "183 ANTI VOX GAIN".
By proper adjustment of these controls, hands-free
voice-actuated operation is possible.
METER:
This indicator determines the function of the meter
during transmission.
Indicates the RF Power Output, from 0
PO:
to 150 Watts on transmit.
Indicates the relative ALC voltage.
ALC:
SWR: Indicates the Standing Wave Ratio
(Forward/ Reflected).
COMP: Indicates the speech compressor level
(SSB mode only).
Indicates the final amplifier drain cur-
ID:
rent.
Indicates the final amplifier drain volt-
VDD:
age.

PROC ( Processor):
This indicator enables the Speech Processor for
SSB transmission. Adjustment of the Processor
level is accomplished via the [ PROC/CAR ] knob.
A :
dvice
 The Speech Processor is a tool for increasing
the average power output through a compres-
sion technique. However, if the Processor level
is advanced too far, the increase in compression
becomes counter-productive, as intelligibility
will suffer. We recommend that you monitor
the sound of your signal using the Monitor (with
headphones).
DNR:
This indicator turns the Main band (VFO-A) re-
ceiver's Digital Noise Reduction circuit on and off.
Adjustment of the Noise Reduction level is accom-
plished via the Menu item "110 DNR LEVEL".
MIC EQ:
This indicator enables the Three-Band-Parametric
Microphone Equalizer. The Equalizer settings are
activated via the Menu.
DNF:
This indicator turns the Main band (VFO-A) re-
ceiver's Digital Notch Filter on and off. This is an
automatic circuit, and there is no adjustment knob
for the DNF.
KEYER:
This indicator toggles the internal CW keyer on
and off. The Keyer sending speed is adjusted via
the front panel's [ MIC/SPEED ] knob and the CW
Hang Time is adjusted via the Menu item "064
CW BK-IN DELAY".
ZIN/SPOT:
This indicator enables the CW receiver spotting
tone. By matching the SPOT tone to that of the in-
coming CW signal (precisely the same pitch), you
will be "zero beating" your transmitted signal with
the frequency of the other station.
