SAFETY INSTRUCTIONS
CAUTION!
• The LTM1’s Class II laser pointer emits less than 1mW of
radiation at 620 to 690 nm (nanometers). However, avoid
looking directly at the laser, and never point it at people
or animals. Eye protection is normally afforded by the
blink reflex. U.S. law prohibits pointing a laser beam at
aircraft; doing so is punishable by a fine of up to $10,000
and imprisonment.
• Do not operate the LTM1 in explosive environments
containing flammable liquids, gases or dust. Sparks may
be created in the tool which may ignite the dust or
fumes.
• Keep the LTM1 away from cardiac pacemakers. A
magnet inside the tool generates a field that can impair
their function. Likewise keep the tool away from
magnetic data storage media, whose contents may be
erased by the magnetic field.
SETUP INSTRUCTIONS
INSTALL BATTERIES
The LTM1 is ready to use after you install the two supplied
“AAA” batteries. To open the battery compartment (Fig. 1,
Callout 7), use the included Phillips-head screwdriver to
turn the screw securing the compartment cover
counterclockwise until it swings up on its hinge at the top.
Install the batteries in series by following the polarity
marks on the inside of the cover. Then swing the cover
down and tighten the screw to secure it.
