Setup

  1. Power Source:
    • Battery Power: Open the battery compartment cover on the bottom of the unit. Insert 4 x AAA batteries (not included) according to the polarity markings. Close the cover securely.
    • USB Power: Connect the provided USB cable to the D.C. 5V port on the projector. Plug the other end of the USB cable into a compatible USB power adapter (e.g., phone charger, computer USB port) or a power bank.
  2. Placement: Place the projector on a flat, stable surface in the desired room. For best projection results, place it in a dark room.
