WARNING • Do not use or store in a place with explosives, a strong magnetic field or combustible gas. • Unauthorized dismantling or modification of this borescope voids the warranty. • Make sure the power is turned off before putting the instrument into the carrying case. • Never touch the camera / LED module during or immediately after 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 off 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 fingertip 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. The borescope should always be stored with the bending section straight (do not force the bending section with your fingers – always use the joystick to adjust and straighten the bending angle.) I 4 • 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 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 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 fire 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 fire. 6. Do not immerse the batteries in liquid of any kind. 7. Do not charge the batteries near an open flame, as it could lead to an explosion or fire. 8. Do not drop, puncture, impact or apply pressure to the batteries as it could lead to an explosion or fire. 5 WARNING…

CLEANING THE BASE UNIT Wipe the base unit with a dust-free cloth as needed. 9.2 REPACKING 1. Return the borescope to the case carefully in order to avoid unintentional damage to the insertion tube or camera / LED module. 2. Be sure that the joystick is in the center / neutral position and that the bending section is straight prior to inserting the borescope into the case. 3. When returning the borescope to the case, first carefully feed the insertion tube into the coil-wheel slot, then place the base unit into the case only after the insertion tube is fully inserted. 9.3 STORAGE Store at normal room temperature and humidity.
