I USER NOTICE Please read this user manual carefully before operation. 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.
• 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.
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 flammable gas or materials. ATTENTION 1.
