2. Forward/Reverse: Press the top button for forward rotation (tightening) or the bottom button for reverse rotation (loosening).
3. Torque Adjustment: Press the middle button (Torque Adjustment Button) to cycle through the three available torque settings: 0.15 Nm, 0.35 Nm, and 0.7 Nm. Select the appropriate torque to prevent overtightening or stripping screws.

6.2 Manual Mode Operation

For tasks requiring higher torque or when the battery is depleted, the screwdriver can be used manually.

1. The electric screwdriver can be used as a manual screwdriver by simply rotating it by hand. It provides a manual torque of up to 5 Nm.
2. Alternatively, use the dedicated manual screwdriver handle provided in the kit for tasks that require more grip and leverage.

6.3 Using the Anti-Static Wrist Strap

To protect sensitive electronic components from electrostatic discharge (ESD), use the anti-static wrist strap.

1. Wrap the wrist strap snugly around your wrist.
2. Connect the coiled cord to the metal clip on the strap.
3. Attach the metal clip to a grounded object, such as a metal computer case or a grounded outlet cover screw. This equalizes the electrical charge between your body and the electronic device.

1. Insert the flexible extension shaft into the magnetic bit holder of the electric screwdriver.
2. Insert the desired precision bit into the end of the flexible extension shaft.
3. Bend and maneuver the shaft to reach the screw.
