Televisions for use in hotels
It is possible to use ordinary televisions, intended for domestic use, on many hotel systems. However, there are televisions with features particularly suited to hotels including:
- the ability to lock many of the controls, such as tuning and brightness, so that users are unable to change them;
- the ability to configure all the settings on the television in a few seconds, via a special programming device;
- a clock and alarm that turns on the television. Some televisions with alarms clocks extract the time from teletext signals which are only available on analogue transmissions. At present most digital receivers do not generate any form of teletext time signal for setting the clock.
