Sim2 Multimedia HT300 Link Switching On And Off, b, Switching On From Stand-By

5 SWITCHING ON AND OFF

The HT300 LINK system consists of the Projector and the DigiOptic™ Image Processor (which is also the system control centre). The DigiOptic™ Image Processor sends commands to the Projector and receives operating status information from the Projector and function commands from the user. The system can be controlled from either the remote control (via the infrared sensors on the DigiOptic™ Image Processor and on the Projector) or the keypad located on the rear of the Projector.

The two units have separate power supplies however: after connecting the unit to the electrical mains supply:

1)Set the two power switches to “I”; the DigiOptic™ Image Processor power switch is located on the external power supply unit (Fig. 13c), while the Projector switch is on the rear panel (Fig. 13a).

2)Turn on the DigiOptic™ Image Processor by pressing the button on the front panel (Fig. 13b).

After a few seconds (system initialisation interval), the DigiOptic™ Image Processor and the Projector assume stand- by mode.

System status information is provided by two LEDs (green and blue) on the front panel of the DigiOptic™ Image Processor, a blue and green LEDS on the rear of the Projector.

Significant status signals are given in Table 3.
