LCD module layout
LCD control module is pretty simple and self-explanatory, but let us have a quick look, note you can disable keys by
soldering over the “Lock Keys” solder bridge:

POWER indicator LED. Illuminated whenever you turn on the exciter.
5, C
ERROR indicator LED. This LED is activated when RF output stage is NOT active. For example,
whenever if temperature protection is activated, this LED illuminates and RF power is reduced.
Important: This LED is also illuminated whenever you change frequency as the control unit turns RF
power off until adjustments are finished and VCO is locked. In such case this does not signal a problem
with temperature or SWR.
