1) CB Band Inhibit
T
he amp will shut down the transmission when
driving signal of 26,000 through 27,999 (CB
band) is detected due to FCC rule. When
combining with ICOM and Kenwood radios,
frequency data of operation is passed to CPU,
even at RX state, to prohibit the transmission.
EXCDMHz Is signed on LCD. (Freq. exceeded)
EXCDMHz AUT-CIV ANT-A
STBY Temp35C OUT_Hi
With ICOM, KENWOOD
28 MHz AUT-YAE ANT-A
PROT INHIBIT FREQ
With YAESU, Manual Band Set, Frequency Count Band Set
2) OPER. MODE Switch
The amp will be shut down, if POWER switch
is turned on, while OPER/STBY is set at
OPER. PSE STBY OPERSW! To reset,
switch OPER. off and on. This is to avoid
unintended sudden transmission, for your
safety

D lamp lights when FET drain currents
exceeds 55A, and is a kind of peak current
indicator. It is not a problem, if it lights only at
a voice peak (SSB).

3) TRACK Sign
3.5 MHz AUT-CIV ANT-A
TRCK Temp35C OUT_Hi
TRACK (Tracking) sign will appear, when the
BAND changes , for a short period of 0.2 sec.
This indicates that band frequency data is
being sent over to combined auto tuner.
When with Yaesu Radio, and with manual band
set and freq. count band set methods, the amp
transmission will be shut down when at TX
PROT INHIBIT FREQ will appear on LCD.
