Coherence Plus Sensor Charging and Battery Guidelines

Always charge the Bluetooth Sensor pod for at least 2 hours before first use.
Use a wall plug adapter for charging. Charging from a computer or laptop USB port may not provide adequate power.
Use a high-quality USB-C cable. If the device does not charge properly, try another cable to rule out a faulty connection.
Ensure that the charging cable is securely connected to the device.
During charging, you may disconnect and reconnect the charging cable once or twice to help initiate the charge cycle.

If the device is not charging or not holding a charge, follow these steps:

Unplug the Ear Sensor from the Bluetooth Sensor pod.
Connect the Bluetooth Sensor pod to power using a wall plug and allow it to charge for approximately 2 hours.
Try a different USB-C cable if you suspect the current one may be faulty.
Once charged, disconnect the charging cable.
Reattach the Ear Sensor to the Bluetooth Sensor pod.
Turn on the device and try running a session again to confirm successful charging.

If the device does not power on after performing the above steps, check the charging port for debris or damage.
Avoid using third-party fast chargers as they may supply incompatible voltage.
Contact customer support if the device still fails to charge or hold power after following all steps.
