other equipment drawing as much as 500
watts. The outlet is unswitched and provides
power regardless of whether the hk775 is on
or off.

When power is on, the POWER indicator (6)
will light.
Power level display
The power output of the hk775 can be
monitored by observing the LEDs on the
POWER LEVEL DISPLAY (9).

power output reading will range from 0.1
watts to 200 watts as indicated by the left 88
