OPERATION

SWITCHING ON AND OFF

The RTX system consists of the Display and the DigiOptical Image Processor (which is also the system control centre). The DigiOptical Image Processor sends commands to the Display and receives operating status information from the Display and function commands from the user. The system can be controlled from either the remote control (via the infrared sensors on the DigiOptical Image Processor and on the Display) or the keypad located on the top of the Display.

The two units have separate power supplies however: after connecting the unit to the electrical mains supply, set the two power switches to “I”; the DigiOptical Image Processor power switch is located on the external power supply unit (Fig. 6a), while the Display switch is on the Display rear panel (Fig. 6b).

After a few seconds (system initialisation interval), the DigiOptical Image Processor and the Display assume stand-by mode. System status information is provided by two LEDs (green and blue) on the front panel of the DigiOptical Image Processor, a blue LED on the front of the Display, and the keypad status (off or illuminated).

Significant status signals are given in Table 3.

If the “No optical link” or “Error” signals are active the system cannot be operated; if the “Warning” signal is active the system

input; pressing 0 selects the input active at the time the system was last switched off.

If the system is switched on very soon after it was last switched off, the lamp may fail to come on because it is too hot. In this case just wait a few minutes to allow the lamp to cool.

Switching the system off :

from the remote control ( key)

from the Display keypad ( key).

If you wish to power off the system completely, wait at least one minute in stand-by before setting the mains power switches on the units to the “O” position or disconnecting the power supply
