Occiam T17 Pairing: Learn How to Pair and Use Occiam Earbuds with BT5.0

Since the charging case for your Occiam T17 earbuds sustained physical damage from a fall and has stopped charging, there are a few steps you can take to troubleshoot or resolve the issue:

• Check the Charging Port: Inspect the Type-C charging port on the case for any debris or misalignment caused by the impact. Ensure the charging cable is fully seated.
• Clean the Contacts: Even if the case itself isn't taking a charge, ensure the internal pins are clean. The manual suggests using an alcohol rag to clean the magnet connectors on both the earbuds and the charging case to ensure a good connection.
• Verify the Cable and Power Source: Test with a different Type-C cable and a known working USB wall charger to rule out cable failure.
• Replacement Case: If the internal circuitry of the case was damaged during the fall, it may not be repairable. According to the official FAQ, if you need a replacement charging case, you should contact Occiam directly. You can reach their after-sales service team via email at the contact information provided on their official website (occiam.com) or through your original purchase platform to inquire about purchasing a standalone replacement case.

It is frustrating when your audio cuts out during important calls. Based on the Occiam T17 manual and troubleshooting guides, here are several steps to resolve this issue:

• Check for Interference and Range: Ensure your phone is within 33 feet of the earbuds and that there are no major obstacles between them.
• Clean the Charging Contacts: The manual notes that oxidized magnet connectors can cause connection issues. Use an alcohol rag to clean the metal contacts on both the earbuds and inside the charging case to ensure they are making a solid connection.
• Reset the Bluetooth Connection:
  1. Go to your phone's Bluetooth settings and "Forget" or remove the T17 device.
  2. Place both earbuds back into the charging case and close the lid for at least 10 seconds.
  3. Open the case, remove the earbuds, and pair them again with your phone.
• Disable Power Saving Mode: The manual specifically suggests turning off Power Saving Mode on your smartphone, as this can sometimes weaken the Bluetooth signal to save battery, causing the audio to drop during calls.
• Check Battery Levels: Ensure the charging case is not at low battery. If the case is low, the earbuds may not stay properly synced or disconnected when they should.

If these steps do not resolve the "dead silence" during calls, you may have a defective unit. Since you have had them for less than a week, you can contact Occiam after-sales service for a replacement or return.

If your right earbud is blinking blue slowly while the left one works, it usually indicates that the earbuds have lost their TWS (True Wireless Stereo) pairing with each other. To resolve this, follow these troubleshooting and reset steps:

• Clear Bluetooth History: Go to your phone's Bluetooth settings and "Forget" or delete "T17" from the list of paired devices. Turn off Bluetooth on your phone.
• The "Case Reset": Put both earbuds back into the charging case and close the lid. Wait for at least 1 minute. This often triggers a soft reset. Open the case and take both earbuds out simultaneously. They should automatically attempt to pair with each other first (the "R" earbud should flash red-blue, while the "L" earbud flashes blue).
• Clean the Contacts: If one earbud isn't responding correctly, use an alcohol rag to clean the magnet connectors on both the earbuds and inside the charging case. Oxidized connectors can prevent the earbuds from properly resetting or syncing when placed in the case.
• Manual Power On: If they don't pair automatically when removed, press and hold the MFB (Multi-Function Button) on both earbuds for about 3 seconds until you hear "Power on."

Once the earbuds are synced to each other (indicated by the "R" earbud alternating red-blue and the "L" earbud flashing blue), reactivate Bluetooth on your phone and select "T17" to reconnect.

To connect your Occiam T17 earbuds to a Garmin Fenix, you must first ensure the earbuds are in pairing mode and not currently connected to another device like your phone.

1. Enter Pairing Mode: Take both earbuds out of the charging case. They should automatically power on. If the "R" earbud flashes red and blue, it is ready to pair. If they are already connected to your phone, turn off Bluetooth on your phone temporarily to release the connection.
2. Prepare the Garmin Fenix: On your watch, hold the Menu button, scroll to Sensors & Accessories, select Add New, and then select Headphones.
3. Select the Earbuds: Your watch will search for nearby Bluetooth audio devices. When "T17" appears on the watch screen, select it to complete the pairing.

Troubleshooting Tips:
