• NOTE
the following regarding the tip of the insertion tube (bending section and
camera module), which is the most delicate part of this video borescope.
• DO NOT
impact the tip of the insertion tube while inserting or
maneuvering inside the equipment being borescoped.
• ONLY
manipulate the joystick gently. Rapid movement of the joystick while
borescoping may cause abrupt impact with the machinery and result
in damage to the camera module or articulation.
• ONLY USE
the recommended alcohol solution when the lens is dirty or greasy
and needs to be cleaned.
• DO NOT force the joystick! If there is unusual resistance to joystick movement
while conducting an inspection, it is because there is physical resistance inside
the inspection area. Trying to force the joystick in this situation will result in
damage to the articulation control wires, the joystick assembly or to the equipment
being inspected.
• DO NOT
impact, press with excessive force or scratch the OLED display.
• DO NOT
cover the unit with a plastic bag or other similar protective covering
during use. It may cause the unit to overheat and damage the internal circuitry.
• DO NOT use or store the borescope in a high temperature, high humidity or high
radiation environment.
