Overview
CT3924 Infrared thermometer is a non-contact temperature
measuring instrument using infrared technology and laser pointer.The
instrument features a low consumption design. It has a LCD with backlight,
a laser pointer for accurate aiming and capable of auto holding the
readings. It has the advantages of rapid measuring, easy operation and
portability.You could use this product to measure the surface temperature,
which is not suitable for traditional measuring ( such as moving objects,
charged objects, toxic objects or hard-to-reach objects).
CT3924 Infrared thermometer is Class II laser product and in
compliance with EN60825-1.
Safety Instructions
Failure to follow the instructions listed below may cause personal injury.
Read and understand all instructions prior to any operation.
Do not remove any labels from the tool.
Do not operate the tool with the presence of flammable/explosive
gases.
Do not operate the laser tool around the children or allow children to
operate the laser tool, failure to do so will injure eyes of children.
Do not stare into the laser beam.
Do not project the laser beam directly into the eyes of others.
Do not set up the tool at eye level or operate the tool on or near a
reflective surface, as the laser beam could be projected into your
eyes or the eyes of others.

Do not observe the laser beam by using optical tools such as
binoculars and magnifying glass.
To avoid burning danger, remember that the reflected objects make
the measuring temperature lower than the real one.
Warning

Battery Safety Instructions
●Please remove the batteries when clean the product.
●Remove the batteries before long term storage
●Please install the batteries properly as the instructions of the positive
and negative charges
●Please dispose the batteries properly. High temperature will cause
explosions and do not burn the batteries. Strap insulated tape around the
battery charges to avoid unsafe contacts with other objects. Many
countries have regulations regarding battery disposal. Please follow the
local regulations of battery disposing.

Operation Instructions
1. Open the battery compartment, insert one 9V battery (6F22/6LR61),
close the lid.
2. Point the product to target objects, hold the trigger to read the data.
3. Field of view: Be sure the target area is larger than the unit’s spot
size. The smaller the target get, the closer the measured distance. For
precise measuring, make sure the target is at least twice as large as the
spot size.
Operation Notes
1、No glass、plastic or water vapor .etc should between the
product and target object.
2、Keep the product away from the following places, which will
damage the devices:
a、Environment has vapor and dust;
b、EMF places（Electro-magnetic fields: such as arc welders、
induction heaters）;
c、Static environment;
d、Heat shock (by abrupt temperature changes, allow 30
minutes for unit to stabilize before use.);
e、High temperature objects;
3、The product can’t be used for medical evaluation, it measure
the body temperature for your reference only.

● Maintenance
1、Cleaning the lens: Abrupt temperature changes will cause vapor,
please clean after the vapor disappears. Blow off loose particles using
clean compressed air. Gently brush remaining debris away with a camel’s
hair brush. Carefully wipe the surface with a moist cotton swab.
2、Keep clean; Avoid drop and wet; The housing could be cleaned with
wet sponge.
