User`s manual

described in the relevant Standards. This protection is fail-safe and is not
compromised by loss of battery power or other electronic failure.
The Servo Glas® 5000X Autolift welding filter cartridge is fitted with two
independently operated sensors that detect the welding arc and respond
accordingly resulting in the appropriate darkened filter state as set by the user
and as indicated on the scaled adjustment. Please note that professional
judgement may be required to achieve the best results. When in doubt consult
an authorized safety representative or your Servo Glas® distributor and always
maintain a conservative attitude towards operation.
Two replaceable lithium batteries type CR2032 (3V) are used as major power
sources. An additional solar cell panel extends battery life and ensures efficient
operation. When operating normally the welding helmet will switch on
automatically and switch off automatically to save power a few minutes after the
last welding arc has been detected.
To provide a general check of system status you may wish to set the shade
control to 11 and hold the helmet towards a bright incandescent light
source. Under normal circumstances the filter will change from light to dark
state and back to light state again as you move the helmet away. Please note
that if you have any questions or there is any doubt about the performance of
your Servore product you should refer to your authorized safety representative
or Servo Glas® distributor.
