To open, hold the Locking Pill Bottle in your left hand and the locking cap in your right hand. Align each digit of your 4-digit code with the arrow at the top of the cap. Your 4-digit code will read left to right. For example, if your 4-digit code is 1234, 1 will be on the left (bottle side) and 4 will be on the right (cap side). Once your 4-digit code is aligned, pull the cap straight up off the top of the bottle without any twisting motion. To close, make sure that your 4-digit code is aligned with the arrow at the top of the cap before placing the cap back onto the bottle. Once the cap is placed back on the bottle, twist the rings to scramble the combination and LOCK the bottle. Verify the cap is secured by attempting to remove it.
