USER NOTICE
Please read this operating manual carefully before operation.
WARNING
1. Donotuseorstoreinaplacewithexplosives,astrongmagneticeldor
combustible gas.
2. Unauthorizeddismantlingormodicationofthisborescopevoidsthe
warranty.
3. Makesurethepoweristurnedobeforeputtingtheinstrumentintothe
carrying case.
4. Never touch the lens/LED module during or immediately after use. Contact
may cause burns.
5. Ifsmokeorabnormalnoiseisdetected,stopusingandturnothebore-
scope immediately.
6. Do not look directly look at the light from the end of the insertion tube. It
is extremely bright and can cause eye damage.
7. Ifanyabnormalityisnoticedduringoperation,stopusingandturnothe
borescope immediately.
ATTENTION
1. Only use this borescope within the approved operating
temperature range.
2. DO NOT over-torque, bend, twist, or fold the insertion tube. Doing so
could damage the articulation control wire assemblies and/or electrical
wiring.
3. Only use the power adapter provided by Viewtech.
4. 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:
a. Be sure that the bending section (distal tip of the insertion tube)
is straight. Use the joystick to remove any angle before attempting
removal.
b. If the insertion tube becomes stuck during removal, gently rotate
the joystick until it becomes loose again.
5. After use, center the joystick in order to straighten the bending section
prior to storage. The 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.)

6. NOTE the following regarding the tip of the insertion tube, which is
the most delicate part of this video borescope:
a. Do not impact the tip of the insertion tube while inserting or
maneuvering inside the equipment being borescoped.
b. 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/LED module.
7. If the lens is dirty or greasy, it may be cleaned by wiping with alcohol.
8. 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.
9. DO NOT impact, press or scratch the LCD monitor.
10. 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.
11. DO NOT use or store the borescope in a high temperature, high humidity
or high radiation environment.
BATTERY AND 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batteryisplacedintotheslotinthecorrectdirection(+/–).
3. Do not carry or store the battery where it may collide with metal objects.
4. Alwayskeepthebatteriesawayfromreorothersourcesofintenseheat,
as it will cause an explosion.
5. Do not attempt to open or modify batteries, as this could lead to an explo-
sionorre.
6. Do not immerse the battery in liquid of any kind.
7. Donotchargethebatterynearanopename,asitcouldleadto
anexplosionorre.
8. Do not drop, puncture, impact or apply pressure to the battery 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batteryinthevicinityofammablegasormaterials.
ATTENTION
1. Do not use or store the battery or borescope in a high-temperature envi-
ronment, such as direct sunlight, closed cars or near heating equipment.
2. The battery will heat up during prolonged operation. Do not remove
immediately after use, as this could cause burns.
3. Keep battery and borescope out of the reach of children.
4. Do not touch the battery electrodes with wet hands.
5. Full charge the battery before use and after extended use.
6. Remove the battery 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. This is a high-output battery. Please use the battery properly or it may
cause damage due to the leakage and excessive heat. Always check the
orientation/polarity and load it 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 battery in accordance with the local regulations at the end of
its 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 50°C (14° to 122°F)
5. Using, charging, or storing the battery at a temperature out of the above
range will reduce the battery’s performance and service life.
6. Be sure to remove the battery from the borescope for long term storage.

II PRODUCT OVERVIEW
The VJ-3 mechanical articulating video borescope is a nondestructive visual
testing instrument with integrated optics, illumination, image processing
and joystick-actuated steering. It is used for the remote visual inspection
of machinery, equipment and components. The VJ-3 facilitates the visual
recording and photo documentation of an inspection of parts and areas of
vital equipment that are otherwise inaccessible or that would require great
eortandexpensetoaccessdirectly.TheVJ-3consistsoftwomodules
integrated into one system: the insertion tube with distally mounted camera/
LEDs, and the base unit with control panel, LCD monitor, power source and all
necessary circuitry.
TheVJ-3isavailablefromthefactoryinavarietyofcongurationssuitablefor
dierenttasks,withoptionalinsertiontubelengthsanddiameters,aswellas
dierentlightwavelengths:white,infrared,orultraviolet.
The video signal from the VJ-3 can be viewed on the integrated LCD display
or on an external hard-wired monitor.
