What do a flashing red light on a motor trend bluetooth headset mean?

Flashing red light means your battery is depleted and you need to connect to a charger.

1. Charge the headset:Headset is charged via USB cable, the light will be red when charging. When the battery is fully charged (about 2-3 hours), the red light of the headset will turn off automatically or the red light turns blue.
2. Turn on the headset:Press the on / talk button on the headset for about 5 seconds until the blue and red flashes alternately (or blue flashes or the blue lights all the time ), now the headset is ready to be connected to the iPhone.
3. Go to Settings, and tap Bluetooth. Turn on Bluetooth.
iPhone will automatically start searching for Bluetooth devices. Tap the device in the Devices list, then follow the onscreen instructions to connect to it. After matching successfully, the blue light on the headset will flash twice per time.
4. Call: when you finish all the above steps, you are going to talk via the Bluetooth headset. When there is incoming call, press the on / talk button, you can talk with Bluetooth headset, when you want to end the call, press the on / talk button, you can end the call.
5. Turn off the headset: Press the on / talk button for 5 seconds until the red light of the headset flashes quickly for twice, then release the button, the headset will be turned off.

Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.

Well first turn your phone's bluetooth ON Then turn ON your headset.Wait for the indicator light to turn from red to blue. (if it doesn't turn off your headset then turn it back on) Press and hold the Call Control button until the indicator light flashes red and blue. (meaning it's starting to pair) Set your phone to find/add bluetooth device and select your headset from the list found When pairing is successful the indicator light should turn blue and your phone will confirm the pairing.

hope that helps....

If you mean pairing, then hold the button down until both red & blue lights flash. If your bluetooth transmitter is in paring mode too, it will connect up. Note that the headset must be off before you begin.

Press the power button for 5 seconds until the LED flashes a alternating red / blue.
Default pass code is "0000"

Step 1 - To reset your Bluetooth headset:

1. Press and hold down the volume keys "+" and "-" on your headset at the same time, until your hear a beep and the light flashes red and green alternately.
2. Press and hold down the volume keys on your headset until it is turned off. The headset is now reset as it was when purchased.

Step 2 - To pair the headset with your phone:

1. Make sure the headset is turned off.
2. Turn on the Bluetooth function and Bluetooth visibility in your phone (This makes the phone visible to other Bluetooth devices).
3. Place the phone within 20 cm (8 inches) from the headset.
4. Press and hold down the call handling key on the headset until it beeps, shows a steady green light and then flashes red and green alternately. If the indicator light only flashes red or green, simultaneously press and hold down both volume keys until the headset beeps and flashes red and green alternately.
5. If your phone supports auto pairing, press "Yes" when you are asked to add the headset to the phone. If not, check your phone User Guide on how to pair the Bluetooth device. If required, the headset passcode is 0000.
6. The headset beeps and flashes green when successfully paired.

When it is turned off, hold the main button in for 4 seconds until the light flashes red, the release. It should flash red and blue. This means it is in pairing mode.
