The Classic-T models 300W, 550W and 900W have built-in tilt protection. This is activated when the heater is moved above 60 degrees. This tilt protection can be deactivated and reactivated. This is done as follows:
Switch off the heater (wait until both LEDs have gone out), then switch the heater on again via the on/off switch while holding down the ‘M’ button, but keep the ‘M’ button pressed for approx. 5 seconds, then release -> the tilt protection is now deactivated.
The same applies to reactivating it.
