TIP
NOTE:
¡ If a lighting system is employed together with
some types of computers and inverter air-
conditioners and/or the regulated power supply
for TV sets, the lights might suffer flickering. This
phenomenon is not a trouble of the generator: it is
caused by poor matching between the above-
mentioned regulated power supply and the
generator's automatic voltage regulator. In such a
case, modify the load combination and make sure
no flickering appears any longer.
