hazardous radiation exposure, electric
shock, fire and/or serious injury.
Keep the laser receiver away
f r o m i m p l a n t s o r o t h e r
medical devices such as
pacemaker or insulin pumps.
The magnets generate a field that can impair
the function of implants or medical devices,
which may lead to serious personal injury.
• Keep the
l a s e r r e c e i v e r
away
from magnetic data medium and
magnetically sensitive equipment. The
effect of the magnet plate 8 can lead to
irreversible data loss.
• Have the
laser receiver
repaired only
through qualified specialists using
original spare parts. This ensures
that the safety of the
laser receiver
is
maintained.
• Do not operate the
laser receiver
in
explosive environments, such as in the
presence of flammable liquids, gases
or dusts. Sparks can be created in the
laser receiver
which may ignite the dust
or fumes.
• Read and strictly observe the safety
warnings in the operating instructions
of the rotational laser.
