Reset Button
Press Reset button to check if the lens
is working properly.
When the Reset button is pressed, the
lens should darken twice and return to
the clear state. Do not use the helmet
if the lens does not function as de-
scribed. (See Section 3-13, Trouble-
shooting.)

Low Battery Indicator
The low battery indicator lights when
2−3 days of battery life remain.
If battery power is low, replace with
CR2450 lithium batteries (2 required)
(Miller Part No. 217 043) (see Section
3-10).

Lens Delay Control
The lens delay control is used to
adjust the time for the lens to switch
to the clear state after welding.
The delay is particularly useful in
eliminating bright after-rays pres-
ent in higher amperage applica-
tions where the molten puddle re-
mains bright momentarily after
welding. Lens delay adjusts from
min (0.10 second) to max (1.0 sec-
ond.).
