Make sure the batteries are fully inserted into place and have sufficient charge; recharge if no LEDs appear. If the batteries show no LEDs even after charging, contact support@dephy.com.

First, verify that your walk training is complete across level ground—this is shown when the LEDs breathe in succession. Once your Sidekick system is trained, the Boost level indicators will display one, two, or three solid LEDs. To adjust your boost level, toggle between the +/- buttons to find a comfortable power level. Keep in mind that walking too slowly, making sharp turns, or pausing can temporarily pause boost; after any stop or non-walking motion, the Sidekick system needs at least two steps to confirm you're walking again before augmentation resumes.

When attaching the Quick Connect to the shoe, make sure the Quick Connect is aligned with the shoe's magnetic cleat and clicks audibly when you rock the Sidekick forward. Clean any dirt or debris from the cleat before reattaching. If you continue to have difficulty attaching the Sidekick to the cleat, contact support@dephy.com.

The battery may have overheated. When this happens, all LEDs pulse white. Allow the battery to cool until the LEDs turn off, then try again.

Power the device off, then back on again. Some noise heard while sitting or not actively walking is normal, but if you hear persistent or grinding noises, discontinue use of your Sidekick and reach out to support@dephy.com.

Turn off your Sidekick, then turn it back on and retrain. When retraining, walk in a straight line on a level surface at around 3 mph. If the problem continues, reach out to support@dephy.com.

Like other footwear, try different tightnesses of the laces, different socks, or added footbeds. If you think you might have the wrong size footwear please contact support@dephy.com.

Reposition the shlever so the top of the shin pad sits about 2 inches below your knee, keeping the Sidekick system close but not touching your leg. Adjust the strap so it's snug but comfortable, and smooth any fabric underneath to prevent irritation. If you continue to experience discomfort, reach out to support@dephy.com.

Just like starting a new workout or breaking in new shoes, it's best to ease into using your Sidekick. Some minor muscle soreness is normal at first, similar to beginning a new routine. Because the Sidekick system may encourage you to walk more or faster than usual, be sure to ramp up gradually so your body has time to adjust. If you continue to experience discomfort, reach out to support@dephy.com.
