4. Assembly

5. Setup
- Placement: Place the stepper on a firm, level surface. Ensure the rubber stoppers on the bottom are securely in place to prevent slipping and protect your floor.
- LCD Monitor Battery: The LCD monitor requires 1 LR44 battery. If the monitor is not displaying, open the battery compartment and insert a fresh LR44 battery, ensuring correct polarity.
- Selecting Exercise Mode: The ST6600 offers two exercise modes: up-and-down stepping and side-to-side twisting. You can switch between these modes using the locking pin located at the front of the stepper.

Image Description: This image illustrates the two operational modes of the stepper. On the left, the 'Up and Down Setting' shows the locking pin inserted into the first hole, enabling vertical stepping. On the right, the 'Side and Side Setting' shows the pin in the second hole, allowing for a twisting motion. This visual guide helps users understand how to switch between the two exercise types.
- Step Mode (Up and Down): Insert the locking pin into the 1st hole. This provides a traditional stair-climbing motion.
- Wriggled Mode (Side to Side / Twister): Insert the locking pin into the 2nd hole. This engages the twisting action, targeting different muscle groups and providing a waist-sculpting workout.
