GETTING TO KNOW YOUR AT-100PROII
Your AT-100ProII is a quality, precision instrument that will give you many years of
outstanding service; take a few minutes to get to know it.
Front Panel:
The front panel of the AT-100ProII features seven pushbuttons, two LED bargraph scales,
and two antenna indicator LEDs:
Func: Activates secondary function of other buttons.
Ant: Selects the active antenna port.
C Up: Manually increase capacitance.
C Dn: Manually decrease capacitance.
L Up: Manually increase inductance.
L Dn: Manually decrease inductance.
Tune: Initiates memory or full tuning cycle. Momentary push places tuner in bypass.
PWR Meter: Bargraph display indicates forward power in 0-12.5 and 0-125 watt ranges.
SWR Meter: Bargraph display indicates SWR during tuning or transmission.
Bypass LED: Lights when in bypass mode.
ANT 2 LED: Lights when Antenna 2 is selected.
Each of the pushbuttons has the primary function listed above when pushed. Additionally,
pressing the FUNC button before pressing any other button will activate that button’s secondary
function.
There is no power button on the AT-100ProII. When the tuner is idle, it enters a low-power
sleep mode, drawing very little current. When the tuner detects a button press or an RF
transmission, it “wakes up,” ready to act.
