Issue 1: Pairing Failure or Device Not Found During First Use?
Analysis: First-time connection failure is usually due to the device not being in the correct pairing mode, or selecting the wrong device from the Bluetooth list.
Troubleshooting Steps:
-
Confirm Power and Pairing Mode:
-
Please verify that the Bluetooth receiver (e.g., sound card, transmitter) is powered on. For example, on the E2 audio interface, the blue indicator light will usually illuminate or flash, signaling that the device is in ready-to-pair mode.
-
-
Accurately Identify the Bluetooth Name:
-
Carefully check the list of available devices on your phone/tablet and select the correct device name.
-
Tip: Our device names usually start with "Maono" or the specific model number. Click on this name to connect.
-
-
-
Restart Search:
-
If the device is not found after a while, try turning off and then turning back on the Bluetooth function on your phone/tablet, then search again.
-
Issue 2: Unable to Reconnect After Successfully Pairing and Then Unpairing?
Analysis: Your phone/tablet's operating system retains a cached record after you "Unpair" or "Cancel Pairing." Clicking this cached record directly will result in a connection failure.
Troubleshooting Steps:
-
Perform "Forget This Device" (Crucial Step):
-
In your phone/tablet's Bluetooth settings, locate the device's name.
-
Do not simply click Connect; instead, select "Forget This Device" or "Unpair" to completely clear the pairing record from your system.
-
-
Reboot and Re-Pair:
-
Restart the Bluetooth receiver/sound card.
-
Turn off and turn back on the Bluetooth function on your phone/tablet.
-
Search for the device name again and click Connect to pair.
-
Issue 3: After Successfully Pairing with One Device, Other Phones or Tablets Cannot Find or Connect?
Analysis: The Bluetooth receiver has a reconnect mechanism. When powered on, it will prioritize automatically reconnecting to the last successfully paired device, making it invisible to new devices.
Troubleshooting Steps:
-
Disconnect the Currently Paired Device (Preferred):
-
Locate the last successfully paired phone or tablet and manually turn off its Bluetooth function.
-
Once the receiver disconnects, the new device will be able to search for and pair with it.
-
-
Force Disconnection and Reset (Alternative):
-
If you cannot locate the previously connected phone (e.g., if it was paired by someone else), please restart the Bluetooth receiver/sound card. Restarting will forcibly disconnect all current connections, forcing the device back into pairing mode, allowing new devices to connect.
-
Issue 4: Normally Connects Fine, But Suddenly Cannot Connect (Especially for iPhone/iOS)?
Analysis: Frequent factory resets of the receiver, or system updates, may cause the locally cached Bluetooth pairing key on the iOS system to become invalid.
Troubleshooting Steps (For iOS Devices):
-
Ignore the Invalid Pairing Record:
-
In your iPhone's Bluetooth device list, find the device's name.
-
Click the information icon ("i" or "!") next to the device name.
-
Select "Forget This Device."
-
-
Rescan and Connect:
-
Search for nearby Bluetooth devices again, and click the name to re-pair.
-
-
Similar Process for Android:
-
Android users facing this issue should select the device in their Bluetooth settings, click "Unpair" or "Forget Device," and then attempt to reconnect.
