turned on.
! Do not point the laser toward the eyes or face
of a person or animal. Laser's potential to
cause damage is retained for hundreds of
feet.

FRONT PANEL DESCRIPTION
• There will be a delay of approximately one
second between the time you initially press
the button and the time the display comes
on.
• Not recommended for measuring on shiny
surfaces. The smaller the target, the closer
the unit should be to it. To avoid thermal
shock, do not store the meter below freez-
ing.

TROUBLESHOOTING
? Meter does not turn on - Check voltage and
relace low battery. Or check time delay which
is allowed 1 second for data to appear on-
screen.
? Data flashing or laser comes on but no
data appears - Check battery voltage and
then replace low battery.
? Dashes appear on-screen - Check extreme
temperature, measure surrounding area to
see if the target exceeds the limit.
MAINTENANCE
Case cleaning:
Clean the exterior housing of the unit with a
damp cloth (use caution). Ensure no water or

soap is allowed inside the meter or on the
infrared lens.
Lens cleaning:
WARNING: We recommend cleaning the lens
periodically to ensure the reading accuracy. To
remove any particles on the lens use low pres-
sure compressed. If the contamination cannot
be removed with air, use a soft cotton swab.
The swab should be slightly damp and very
light pressure should be applied. Do not use
solvents to clean the lens.
