Please read all instructions and warnings before
using this product. Irregular use will cause
damage to the product or personal safety.
Using environment
1）Please read carefully and correctly understand the warning and
operating instructions in the user manual before using the
visual fault locator.
2）
Please use the visual fault locator in strict accordance with the
user manual.
3）Lasers are harmful, so you need to pay special attention to
protecting your eyes. When working with laser, it is strictly
forbidden to look directly at the red light;
4）The laser is a heating device. Generally, the higher the
temperature, the shorter the life of the laser. When using it,
try to avoid high temperature environments. It is not recom-
mended to use it for a long time.
6）When it is not used for a long time, the lithium battery may self
-discharge, and it cannot be turned on when the voltage is too
low. Please charge it before using it.
5）After use, please cover the dust cap to prevent dust from
falling into it.
7）After using for a period of time, please clean the interface with
a special optical fiber cleaning cotton swab.

Standard configuration
This product uses a 650nm semiconductor laser as a
light-emitting device and is driven by a constant current
source to emit stable red light; it enters a single-mode or
multi-mode fiber after being connected to an optical fiber
interface to realize the function of fiber fault detection. It is
a fiber optic engineering construction and a fiber optic
network. An indispensable tool for maintenance, optical
device production and research.
