Setup
- Unfolding the Loupe: Gently unfold the loupe from its compact, folded position until it forms a stable viewing stand. The lens should be positioned above the measurement base.
- Battery Installation (if necessary): The loupe comes with 3 button cell batteries pre-installed. If the LED light does not function, locate the battery compartment (typically on the side or rear of the main body). Open the compartment and insert three new button cell batteries, ensuring correct polarity as indicated inside the compartment.

Operating Instructions
- Positioning: Place the unfolded loupe directly over the object you wish to magnify. Ensure the object is flat against the measurement base for accurate viewing and measurement.
- Activating the LED Light: Locate the small switch on the side of the loupe's body. Slide the switch to the 'ON' position to illuminate the viewing area. Slide it to 'OFF' when not in use to conserve battery life.
- Focusing: While looking through the lens, rotate the focus wheel until the image of the object appears sharp and clear.
- Measuring Objects: Use the etched scales on the base of the loupe to measure the dimensions of the magnified object. The scales are marked in both inches and centimeters.

Maintenance
- Cleaning the Lens: Use a soft, lint-free microfiber cloth specifically designed for optical lenses to gently wipe the lens surface. Do not use abrasive cleaners, paper towels, or harsh chemicals, as these can scratch the lens.
- Battery Replacement: If the LED light dims or stops working, it is time to replace the batteries. Open the battery compartment, remove the old batteries, and insert three new button cell batteries (e.g., LR44 or equivalent), ensuring correct orientation.
- Storage: When not in use, fold the loupe into its compact form and store it in its durable plastic case to protect the lens and mechanism from dust and damage.
