Instead of using their own codes, amplifiers made by Philips react on long presses of power on/off buttons of other Philips A/V components. As an example, one can turn on the Philips amplifier with its TV/AUX input activated by pressing the power on key of the Philips VCR remote about one second. This device file contains power on and off commands for Philips tuner, tape deck, CD player, television and video recorders. For each device, there is a single non-repetitive command, command that repeats itself couple of times, and a command that generates a burst of about one second.
