USER NOTICE
Please read this user manual carefully before operation.
WARNING
• Do not use or store in a place with explosives, a strong magnetic eld or
combustible gas.
• Unauthorized dismantling or modication of this borescope voids the warranty.
• Make sure the power is turned o before putting the instrument into the
carrying case.
• Never touch the camera / LED module during or immediately aer use. Contact may
cause burns.
• Do not look directly at the light from the end of the insertion tube. It is extremely
bright and can cause eye damage.
• If any abnormality is noticed during operation, stop using and turn o the
borescope immediately.
ATTENTION
• ONLY USE this borescope within the approved operating temperature range.
• DO NOT use sharp objects or strong force when touching or tapping the OLED
display. Too much force or using an object besides the provided stylus or ngertip
could damage the screen.
• DO NOT over-torque, crease, twist or fold the insertion tube. Doing so could
damage the articulation control wire assemblies and / or electrical wiring.
• ONLY USE the power adapter provided by ViewTech.
• DO NOT yank or attempt to forcefully remove the insertion tube if it becomes
stuck inside the equipment being borescoped. When extracting the insertion tube
from the inspection area, be sure that the bending section (distal tip of the insertion
tube) is straight. Use the joystick to remove any angle before attempting removal.
If the insertion tube becomes stuck during removal, gently rotate the joystick until it
becomes free again.
• AFTER USE, center the joystick in order to straighten the bending section prior to
storage. e borescope should always be stored with the bending section straight
(do not force the bending section with your ngers – always use the joystick to
adjust and straighten the bending angle.)

• 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.
