more than once within any given time period (up to 30 minutes). This is due to
the unit having a temperature sensitive resistor. While the unit is degaussing, the
resistor increases in value with heat and once it reaches a certain temperature,
the resistance will rise and prevent voltage from reaching the degaussing coil.
This is what stops the degausser, and this device's resistance will decrease as it
cools back off, enabling the degauss function to operate again. This is an
intentional design and is an industry standard, not just for Philips monitors. Please
be aware that not all models in the Philips range has this manual degauss
function. Some models are built with an auto degauss feature which automatically
degausses the monitor when it is switched on.
