How to Set Up and Personalise Your Zeus

Getting started with your Zeus Sleep device is simple. This guide will walk you through charging, positioning, applying Hydrogel Pads, adjusting stimulation, and getting the most comfortable experience possible from your device.

You will find in the box: 

1 x Zeus Device
1 x Zeus charging dock
1 x Zeus charging dock cable
1 x 30 Hydrogel Pads 
1 x User Manual

Step 1: Unbox and charge your Zeus

Remove everything from the box and peel off the yellow sticker from the underside of the Zeus device. If there is any adhesion left on the 4 pins, use a damp soft cloth to remove any residue and allow to fully dry. 

Charging:

Connect your charging cable to the USB port on the charger dock.
Place Zeus onto the charging dock, ensuring the charging pins align correctly. The LED will flash blue while charging and turn solid blue when fully charged. The first full charge can take up to 4 hours.

Use the supplied USB A to USB C cable and avoid fast chargers or high power USB plugs.

If Zeus does not appear to charge:
• Check the charging pins are aligned correctly
• Avoid fast charging plugs
• Ensure no Hydrogel Pad or residue remains on the underside of the device

Step 2: Find the correct position

Before applying a Hydrogel Pad, practise positioning Zeus under your chin in front of a mirror. All anatomies are different, so finding the correct position for your chin is key. 

Place your fingers underneath your chin and raise your tongue to the roof of your mouth repeatedly. You should feel the muscles beneath your fingers contract. The wings of Zeus should sit over this moving muscle area.

Correct positioning varies slightly between users depending on anatomy.

Step 3: Apply the Hydrogel Pad

Ensure the underside of the Zeus device is clean and completely dry before use. If any Hydrogel Pad residue is present, gently clean the area using a soft damp cloth with mild detergent or an alcohol wipe, then allow it to dry fully.

Remove a fresh Hydrogel Pad from the packet and reseal the packaging immediately to help keep unused pads fresh.

Peel away the backing labelled “1” and firmly attach the Hydrogel Pad to the underside of Zeus, applying pressure especially over the hydrogel circles to ensure full contact.

Before applying Zeus, make sure the skin under the chin is clean, dry, and free from lotions or creams. If shaving the area, we recommend shaving in the morning to allow the skin time to settle before evening use.

When ready, peel away the backing labelled “2” to expose the skin-safe adhesive, position Zeus under the chin, and press firmly onto the skin, focusing pressure over the hydrogel circles.

Step 4: Finding the right stimulation level

To switch Zeus on, press the + and – buttons together at the same time. The LED will flash red once followed by green flashes indicating the stimulation level.

Start at level 1 and gradually increase the stimulation until you feel a gentle buzzing or tingling sensation under the chin. The first comfortable tingling sensation is usually the right level for you.

Zeus has 10 stimulation levels to suit different sensitivities. Some users may feel stimulation at lower levels, while others may require higher settings.

Zeus delivers stimulation in a programmed cycle of 6 seconds on and 4 seconds off throughout the night to help maintain upper airway muscle activity during sleep.

The stimulation is designed to feel gentle and comfortable. You do not need strong stimulation for Zeus to work effectively, and you will not feel your tongue move.

Over time, the sensation may become less noticeable as your body adapts. This is normal and does not mean Zeus has stopped working.

If the stimulation feels too strong:
• Ensure skin is clean and completely dry
• Avoid lotions or creams before use
• Try lowering the stimulation level slightly
• Reposition Zeus if needed

After 90 seconds without button interaction, Zeus enters its 20 minute sleep mode. The LED switches off during this time to avoid disturbing your sleep before stimulation resumes automatically.

Step 5: Adjusting stimulation

If you wish to adjust the stimulation after Zeus has entered sleep mode, press the + and – buttons together at the same time to re-enter adjustment mode. The LED will flash to indicate the device is active and ready for adjustment.

Once in adjustment mode, increase or decrease the stimulation as needed.

Zeus is designed this way to help prevent accidental setting changes during sleep.

After 90 seconds without button interaction, Zeus will automatically return to sleep mode for 20 minutes before stimulation resumes.

Step 6: Sleeping with Zeus

As the night goes on, your body stimulation from Zeus may become weaker or completely unnoticeable. This is normal and does not mean the device has stopped working.

Over time, the nerve receptors in the skin can adapt to the sensation of stimulation, making it feel less noticeable while Zeus continues stimulating the muscles connected to the airway during sleep.

If the stimulation feels weaker than expected:

• Press firmly on the device to ensure both electrodes are maintaining full contact with the skin
• Reposition Zeus slightly if needed
• Press the + and – buttons together briefly to check the device is active
• If the LED flashes red followed by green, Zeus is working correctly
• If the LED flashes red only, the battery requires charging

If you would prefer a stronger sensation during the night, you can increase the stimulation level or begin the night on a slightly higher setting.

Many users assess the effectiveness of Zeus through:

• Feeling more refreshed during the day
• Feedback from a partner or family member
• Sleep tracking or snoring apps such as Sleep Cycle

If you are still unsure whether stimulation is being delivered correctly, you can test Zeus on the underside of your forearm, which is often more sensitive and can help with troubleshooting.
