Powering on the screen
When mains power is applied to the Torch Computers 46” and 52” LCD screens, a
bleep or a series of bleeps will be heard. This is the UPS (uninterruptible power supply)
initialising.
As delivered, the computer will not power up when the mains power is applied; the
screen is set up so that the LCD panel turns on as soon as power is applied, but will
shortly go into stand-by mode. The red light will come on and after a short pause it
flashes. (and turns off when the computer starts)
In the unlikely event that the red light is not flashing but shows a steady light, press the
power button once (shown with a green arrow on the previous page). The light should
then start flashing. Alternatively, if a remote control is available, insert the batteries and
use the red power button on the remote.
To start the unit, press the recessed red button on the side of the screen once, briefly
(see previous page). The computer will start and the LCD panel will come on, and the
equipment starts up. The red light will go out and the blue light will come on.
No further user intervention should be necessary, as the screen was shipped in a
configuration such that the artwork animation will start operating automatically, as soon
as the computer has completed its initialisation.
Powering off the screen
WARNING: Do not unplug the mains while the computer is in operation.
When the artwork is running, press the red button briefly and the computer will shut
down, putting the screen into sleep mode.
If the computer is still initialising, wait until the artwork is running before pressing the red
button.
Removing Mains Power from the Screen
Do not remove Mains Power from the Screen except when the computer is shut down.
On later models, there is a blue light which shows that the PC is running. This light will
go out when the computer has shut down.
Once the computer is shut down the mains can be switched off and/or unplugged.
When this is done, the UPS will bleep.
