POWER Switch
This switch turns the VL-2000 “on” and “off”.
When the VP-2000 [POWER] switch is set to the
“off” position, this switch will not function.
If using the Yaesu transceiver with a BAND DATA
Cable, the VP-2000 AC power will be remotely controlled by the transceiver’s power switch when the
REMOTE switch on the rear panel of the VL-2000 is
set to “on”.
Caution: Never turn “off” this switch while transmit-
ting.
METER-1 Switch
Press this switch to toggle the METER-1 function be-
tween “PO” meter and “SWR” meter.
METER-1
This is the two functions (PO/SWR) meter which is
determined by the “METER-1” switch selection.
PO: Indicates the RF Power Output, from 0 to 2k
watts on transmit.
SWR: Indicates the antenna system observed stand-
ing wave ratio (SWR), from 1.0 to 5.0.

tween “ID” meter and “VDD” meter.
METER-2
This is the two functions (ID/VDD) meter which is
determined by the “METER-1” switch selection.
ID: Indicates the f inal amplif ier drain current,
from 0 to 75 A.
VDD: Indicates the final amplif ier d rain volt age
(nominal value: 48 V).
TX Indicator
This indicator glows red when the VL-2000 is trans-
mitting.

ATT Switch
This switch activates a 3 dB input RF power attenua-
tor, to reduce excessive input power from the exciter.
It should be “on” if exciter output exceeds 100 watt
PEP, as is the case when using the FTDX9000 series
transceiver. The LED will glow red, when this switch
is “on”.
Note: This switch does not effect while transmitting.
INPUT Switch
This switch selects the exciters which connected to
the INPUT1 and INPUT2 jacks on the rear panel.
The “INPUT1” or “INPUT2” LED will glow red to
indicate which exciter is in use.
Note: This switch does not effect while transmitting.

normal.
TUNE Button
This is the on/off switch for the VL-2000’s Automatic
Antenna Tuner.
Press this button briey, places the antenna tuner in
line between the transmitter final amplifier and the
antenna connector (The LED will glow red, and reception is not affected).
Press and hold this button for 1/2 second, while re-
ceiving in an a mature band, activates the transmitter
for a few seconds while the Automatic Antenna Tuner
rematches the antenna system impedance for minimum SWR. The LED will blink red when the antenna
tuning is processing.
Pressing this button briefly, while the Tuner is en-
gaged, will take the Automatic Antenna Tuner out of
the transmit line.
HI-SWR LED
This LED blinks red when the antenna system is ab-
normally high SWR condition (over 3.0:1) that cannot
be resolved by the Automatic Antenna Tuner.
When this LED blinks, the exciter output delivers to
the antenna connector directly without through a linear amplier.
Note: Check to be sure that you have the correct an-
ten na selected on the current operating band when
this LED blinks red. If so, you will need to check the
condition of the antenna, its coaxial cable and/or the
connectors on the cable so as to locate and correct
fault.
ANT Button
These momentary buttons select the antenna jack on
the rear panel, with the selection indicated by the red
LED in each button.
Note: These buttons does not effect while transmit-
ting.
BAND Button
These momentary buttons select the amateur band for
the operation, with the selection indicated by the LED
in each button.
If using the Yaesu transceiver with a BAND DATA
Cable, the VL-2000 operation band will be remotely
controlled by the transceiver’s BAND switch.
Note: These buttons does not effect while transmit-
ting.

r When operate the VL-2000 with the FTDX9000MP, should be set the ATT switch on the VL-2000 front panel to “on”
position, and set the maximum RF output power level to “200 W” via menu item “TX GNRL 173 TX MAX POW-
ER” on the FTDX9000MP. The 400 watt power output from the FTDX9000MP is far in excess of what is required to
drive the VL-2000 to its full rated output.
r When operate the VL-2000 with the FTDX9000D or FTDX9000Contest, should be set the ATT switch on the VL-
2000 front panel to “on” position. The 200 watt power output from the FTDX9000D or FTDX9000Contest is far in
excess of what is required to drive the VL-2000 to its full rated output.
r The ALC cable must be connected between the transceiver and VL-2000 to prevent overdrive of the amplier, and
especially to facilitate the proper operation of the protection circuitry if sudden antenna system problems should cause
the SWR to rise to dangerous levels.
r Do not attempt to connect or disconnect coaxial antenna cables when your hands are wet.
noTe
r When the VL-2000 POWER switch is turned “off”, the exciter output is delivered as follows:
¦ INPUT1 exciter: delivers to the ANT1 connector directly.
¦ INPUT2 exciter: delivers to the ANTDIRECT connector directly.
r If you want to link the VL-2000 and FTDX9000 series POWER switches, set the VL-2000 REMOTE switch to the
“on” position.
