PROBLEMI COMUNI E RIMEDI
Attenuazione della luce irregolare = La fascia è stata
regolata male e la distanza fra gli occhi ed il filtro è sbagliata.
(Regola la fascia alla distanza corretta)
Il filtro automatico non si oscura o funziona ad
intermittenza = La lente di protezione esterna è sporca o
danneggiata: cambia la lente di protezione. I sensori sono
sporchi: pulisci la superfice dei sensori.
Funzionamento lento = La temperatura d'esercizio è troppo
bassa: non usare la maschera a temperature più basse di
quelle indicate nelle caratteristiche tecniche.
Visione difficile = La lente di protezione interna e/o esterna
è sporca: cambia la lente di protezione.
