delay), MAX (maximum delay).
9. TROUBLESHOOTING:
1. Erratic shading
a) The headband was set incorrectly and the eye-to-filter distance
varies (readjust the headband to rectify the difference in the
distance).
2. The auto darkening filter does not get dark or it flickers.
a) The front glass is dirty or damaged (clean or replace) .
b) Sensors are dirty (clean sensors) .
c) Welding current too low (set the sensitivity switch to MAX) .
3. Slow reaction
a) Too low operating temperature (do not use the helmet below -
5°C) .
4. Poor vision
a) Front/internal glass and/or filter dirty (clean or replace) .

PROTECTION OF THE ENVIRONMENT:
The symbol nearby denotes that old equipment
must never be thrown away together with other waste (with
the penalty of a fine). Hazardous components of electronic
equipment may adversely affect the natural environment
and human health.
Each household may contribute to the recovery and reuse (recycling) of
old machinery and equipment. Both in Poland and Europe a system for
recovery of used equipment either exists or is being created. The system
obliges all organizations that sell such equipment to collect the used
machinery and appliances. Moreover, general purpose collecting points
for such equipment are available.
