WARNINGS

KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE

To ensure safe operation and service of the instrument, follow these instructions. Failure to observe these warnings can result in serious personal injury, fire, or electrical shock.

• The borescope, including the camera end, is NOT insulated. Avoid probing areas where energized conductive elements may be present. Shut off power to nearby work areas before starting work.
• DO NOT probe moving machinery that could catch the borescope and/or camera end, and cause harm to the operator and the Borescope.
• DO NOT immerse body of borescope in water or liquids. DO NOT use the borescope for underwater inspections.
• Properly seal the charging port cover to achieve specified water & foreign object ingress protection. Keep seal free of dirt, oil, sand, or other material that interferes with proper sealing. Failure to do so can result in risk of fire or electric shock.
• DO NOT open the charging port cover if wet or in a wet environment. Thoroughly dry the unit and the seal around water-resistant cover completely before opening water resistant cover.
