3. Setup

- Initial Charge: Before first use, fully charge the unit. Locate the charging port on the back of the unit. Open the protective cover and connect the provided USB charging cable. Connect the other end to a compatible USB power adapter (not included). The charging indicator light will illuminate.
- Placement:
- For flying insects: Place the zapper on a flat surface or hang it using the integrated handle in an area where flying insects are prevalent.

The Monster Double Zapper features multiple operating modes to target different types of pests.

- Mode 3 (Both): Activates both UV light and the heat/bait system for comprehensive pest control.
- Mode 4 (Heat Only): Activates only the heat attraction in the base.

- For flying insects, place the unit in a central location within the affected area, away from competing light sources.
- For crawling insects, place the unit directly on the floor or counter where pests are observed.
