Connecting your Zekler Sonic 550, 540, or 530 hearing protection to the phone is a simple process that gives you access to sound without compromising your protection. Here are the steps for a smooth connection. Before you start, it is important to check that your hearing protection is turned off. This ensures that you can start the pairing process correctly.

Step 1: Activate pairing mode on your hearing protection

  • Hold down the on/off button: Do this on your hearing protection for about 6 seconds.
  • Check for the LED indicator: Look for an LED that starts flashing red and blue, indicating that the hearing protection is ready for pairing.

Step 2: Activate Bluetooth on your phone

  • Open settings on your phone
  • Turn on Bluetooth: Activate the Bluetooth function so that your phone starts searching for available devices nearby.

Step 3: Select “Zekler Sonic” from the device list

  • Look for Zekler Sonic: On your phone, select "Zekler Sonic" from the list of Bluetooth devices that your phone has found.
  • Have some patience: It may take a while before your device appears in the list.

Step 4: Enter PIN code if required

  • If your phone requests a PIN code to complete the pairing, use the standard code "0000" (four zeros).

Step 5: Confirmation

  • Once the pairing is complete, you should hear a confirmation from your hearing protection, and the LED indicator may change color or pattern to show that the connection is successful.

If you encounter problems
If the pairing is unsuccessful:

  • Try again: Restart your Zekler hearing protection and repeat the above steps.
  • Check charging and distance: Ensure that the hearing protection is charged and within range of your phone.
  • Disconnect from other Bluetooth devices: It may be that you are already connected to a device on your mobile, this can prevent you from connecting your hearing protection.
