ID (LED)
: LED lights when the input drain current is over 20A. This does not
mean that any damage occurred to the amplifier, but is useful for the
user to notice any stress influencing the final FET caused by high drain
current, load impedance trouble, etc. We recommend that you note the
usual condition of the lighting. When any unusual symptoms are
noticed, the user may lower the drive power from the transceiver, check
the antenna SWR, etc.
⑬
FAN (LED)
: LED lights when fan is running at high speed. When the heatsink
reaches 50
℃
the cooling fan will switch to high-speed mode to cool the
heatsink.
⑭
MULTIMETER : Pf (Forward output power), Pr (Reflected power from antenna), Vd
(FET drain voltage), and Id (FET drain current) are shown on the scale
as selected by
