aia °Turns the speech compressor ON and
OFF in SSB and AM modes. (p. 34)
eEnters memory keyer set mode in CW
mode. (pgs. 35, 36)
we turns the % function ON and OFF in
RTTY mode. (p. 24)
- % function sets dial rotation to 1⁄4 of normal for
fine tuning.
V What is the speech compressor?
The speech compressor compresses the transmitter
audio input to increase the average audio output level.
Therefore, talk power is increased. This function is effec-
tive for long distance communication or when propaga-
tion conditions are poor.
© ELECTRONIC CW KEYER SPEED CONTROL
[KEY SPEED] (p. 35)
Adjusts the internal electronic CW keyer's speed.
- 7 wpm (min.) to 56 wpm (max.) can be set.

KEY SPEED
@ SEMI BREAK-IN DELAY CONTROL
[BK-IN DELAY]
Adjusts the transmit-to-receive switching delay time
for CW semi break-in operation.
Short delay for
high speed keying KON
Long delay for
slow speed keying
@ MODE SWITCHES
Selects the desired mode. (p. 25)

PANEL DESCRIPTION 1
@ LCD FUNCTION SWITCHES [F-1]-[F-5]
Push to select the function indicated in the LCD dis-
play above these switches.
- Functions vary depending on the operating condition.
@ SPEECH SWITCH [SPEECH] (pgs. 59, 61)
Announces the selected readout frequency when an
optional UT-102 is installed.
@ TUNING DIAL (p. 23)
Changes the displayed frequency, selects set mode
items, etc.
@ MAIN/SUB SWITCH [MAIN/SUB]
Selects the main or sub readout for access.
- The sub readout frequency is displayed in outline and
functions only during split operation or dualwatch.
@ VFO/MEMORY SWITCH [VFO/MEMO]
e Toggles the selected readout operating mode be-
tween the VFO mode and memory mode when
pushed. (pgs. 22, 41)
*Transfers the memory contents to VFO when
pushed for 2 sec. (p. 44)
@ MAIN/SUB CHANGE SWITCH [CHANGE]
e Toggles the frequency and selected memory chan-
nel between main and sub readouts when pushed.
- Toggles between transmit frequency and receive fre-
quency when the split frequency function is ON. (p. 31)
eEqualizes the sub readout frequency to the main
readout frequency when pushed for 2 sec.
@ DUALWATCH SWITCH [DUALWATCH] (p. 30)
¢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 function)
- The quick dualwatch function can be turned OFF using
set mode. (p. 56)
@® SPLIT SWITCH [SPLIT] (p. 31)
e 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. 38, 57)
e Turns the split function ON and shifts the sub read-
out frequency after inputting an offset (+1 MHz in 1
kHz steps).
