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.
BATTERIES & BATTERY CHARGING
Follow the instructions below for battery care and proper charging
to prevent leakage, overheating, smoke, explosion, electric shock
and burns.
DANGER
1. Only use batteries and chargers specially designed for this borescope: 18650B battery
with PCB-protection (button top).
2. Be sure the batteries are placed into the chamber in the correct direction (+ /–).
3. Do not carry or store the batteries where they may collide with metal objects.
4. Always keep the batteries away from re or other sources of intense heat, as it could
cause an explosion.
5. Do not attempt to open or modify batteries, as this could lead to an explosion or re.
6. Do not immerse the batteries in liquid of any kind.
7. Do not charge the batteries near an open ame, as it could lead to
an explosion or re.
8. Do not drop, puncture, impact or apply pressure to the batteries as it could lead to an
explosion or re.

WARNING
1. Use only 3.6V lithium batteries, model 18650B with PCB-protection (button top).
2. Submit a repair request immediately in case of battery leakage, discoloration,
deformation or abnormal condition.
3. Clean immediately with tap water if your skin or clothing comes into contact with
a leaking battery.
4. Keep the battery charger free of any covering during charging.
5. Do not charge the batteries in the vicinity of ammable gas or materials.
ATTENTION
1. Do not use or store the batteries or borescope in a high-temperature environment,
such as direct sunlight, closed cars or near heating equipment.
2. e batteries will heat up during prolonged operation. Do not remove immediately
aer use, as this could cause burns.
3. Keep batteries and borescope out of the reach of children.
4. Do not touch the battery electrodes with wet hands.
5. Fully charge the batteries before use and aer extended use.
6. Remove the batteries from the borescope if the scope will not be used for more than
30 days, otherwise it may cause damage to the borescope, re or personal injury.
REMINDER
1. ese are high-output batteries. Please use the batteries properly or it may cause
damage from leakage or excessive heat. Always check the orientation / polarity and
load batteries into the chamber correctly.
2. Battery performance will decrease as the ambient temperature drops.
Performance will be restored once the ambient temperature rises.
3. Recycle the batteries in accordance with local regulations at the end of their
useful life.
4. Recommended temperature range for this lithium ion battery is:
• Discharging (in use): 0°C to 40°C (32°F to 104°F)
• Charging: 0°C to 40°C (32°F to 104°F)
• Storage: -10°C to 40°C (14° to 104°F)
5. Using, charging or storing the batteries at a temperature out of the above range will
reduce the battery performance and service life.
6. Be sure to remove the batteries from the borescope for long term storage.
