Indicates critical safety components, and identical components should be used for replacement. Only then can the

operational safety be garanteed. Le remplacement des éléments de sécurité (repérés avec le symbole ) par des composants non homologués selon la

Norme CEI 65 entraine la non-conformité de l'appareil. Dans ce cas, la responsabilité du fabricant n'est plus engagée. Wenn Sicherheitsteile (mit dem Symbol gekennzeichnet) nicht durch Original - Ersatzteile ersetzt werden, erlischt die

In the case of green and red flashing, the power supply cannot be reset with the OFF/ON operation at the mains power supply, remote control, and wall outlet.

For the alarm reset, keep pressing the input changeover key of the main unit and move the mains power supply to the "ON" position at the main unit. While doing so, it is necessary to keep pressing the input changeover key of the main unit for more than two seconds.In the case of green and red flashing, the power supply cannot be reset with the OFF/ON operation at the mains power supply, remote control, and wall outlet.
