VL-1000 Operating Manual
4. LOW Switch
This switch selects the RF output power.
When in the LOW position, the RF output
power will be reduced to (approximately) 500
watts PEP, and “
LOW
” will appear on the dis-
play.
Note: This switch should be set to the LOW
position when operating from a 100 ~ 117 VAC
power source.
5. INPUT Switch
Press this switch to toggle between the ex-
citers connected to the INPUT 1 and INPUT 2
connectors on the rear panel. The indicator
“
INPUT 1
” or “
INPUT 2
” will appear on the dis-
play to indicate which exciter is in use.
6. ATT Switch
This switch activates a 3 dB input RF power
attenuator, to reduce excessive input power
from the exciter. It should be on if exciter out-
put exceeds 100 watts PEP, as is the case
when using the FT-1000/D. The “
ATT
” indica-
tor will appear on the display when this switch
is on.
Front Panel Controls and Switches
1. POWER Switch
This switch turns the VL-1000 on and off.
When the amplifier is turned off, the INPUT 1
jack is connected directly to the ANT 1 jack. If
using a Yaesu transceiver with a B
AND
D
ATA
cable, the VL-1000 AC power will be remotely
controlled by the
transceiver’s power switch
when the REMOTE switch on the rear panel
of the VL-1000 is set to ON.
2. OPERATE Switch
Pressing this switch activates the power am-
plifier section of the VL-1000. When the power
amplifier is activated, “
OPERATE
” will appear
on the display. Press this switch again to turn
off the power amplifier section.
3. DIM Switch
This switch selects the brightness level of
the LCD display. In low-light situations, acti-
vating the Dimmer may reduce excess bright-
ness in the display. For normal room lighting,
however, the Dimmer should be set to OFF
for best visibility.
