Once the cabling and interconnections for the HE4000 are completed, the unit may be powered
up. The HE4000 power switch is a rocker switch located on the front panel. The power switch is
labeled 1/0 where the 1 represents the On position and the 0 represents the Off position.
To power up the HE4000, press the power switch to the On, or 1 position. The power-on cycle
takes approximately 20 seconds, as the unit performs extensive self-diagnostics in this time
period.
