If the power indicators on the headphones and docking station continue to blink once a second, they are no longer paired to each other. If this happens, follow these steps:
- Make sure that the headphones and docking station are within range of each other (ideally in the same room).
- Turn off the headphones and unplug the docking station.
- Turn on the headphones and plug in the docking station. The blue LED on the headphones and docking station will blink every five seconds when paired.

- Set the headphone volume level to the minimum.
- Put your headphones on your head. Adjust the fit until you feel comfortable.
- Turn on your audio source (such as a TV or stereo system) and begin playback. You may need to turn up the volume on your audio source to hear playback.
- Adjust the headphone volume to your normal listening level.
CAUTION: Continuous use at high volume may permanently damage your hearing.
NOTES:
- If the system is connected to a TV, you may want to turn off the TV sound to prevent hearing sound from the TV speakers. Refer to your TV manual.
- If the docking station does not have audio input for more than 15 minutes, the headphones will power off automatically.
- If the headphones are unpaired from the docking station for more than 15 minutes, the headphones will power off automatically.

Maintaining your system
With the docking station unplugged and the headphones turned off, use a soft cloth dampened with a weak solution of mild detergent and water. Dry the device immediately afterwards with a clean cloth. Do not use abrasive cloth, thinners, alcohol, or other chemical solvents, because they may damage the finish or remove the panel lettering.
Troubleshooting
No power
- Make sure that the batteries have been charged.
- Try power cycling the docking station by unplugging it and plugging it back in.
- Try another power outlet.
My headphones are not charging
- Make sure that the headphone’s charging contacts and the docking station’s charging pins make contact. You might have to rock them back and forth to make a good connection. The docking station Charging indicator turns red to indicate the headphones are charging.
There is no sound
- Check the volume level of the headphones or audio sources connected to the docking station.
- Make sure that all of the cables are connected correctly and that the cables are not connected to the AV input jacks on your TV, or the AV Output jacks of the docking station.
- Make sure that your source device is turned on.
- Make sure that the Power/Pairing indicators of the headphones and Pairing indicator on the docking station are blinking blue (every five seconds), see “Turning on and pairing the system” on page 15.
- Make sure that the audio source has internal/ external speaker settings that allow the internal speakers to be turned off and for the sound to be heard from the external source (your headphones).
- Make sure that your audio source is not set to Mute.
- To maximize your volume level through the system, make sure that your audio source (for example, a TV or MP3 player) has its volume turned up to at least 50% of its volume level.
There is sound interference
- Move the docking station slowly to find the best reception position for your headphones.
- Shorten the distance between your headphones and the docking station. The maximum distance is 33 feet (10 m), but walls and other obstructions will limit this distance.
- Make sure that all of the cables are connected correctly.
- It is possible that other devices like cordless phones, microwaves, or wireless routers may be causing interference. Try turning one device off at a time to determine which device is causing interference.
- If your cordless phone or wireless router is causing interference, try changing the channel it is using. Also, try moving the docking station away from all WiFi routers, cordless phones, cell phones, Smart TVs, and microwave ovens. Refer to your device’s owner manual.
There is sound coming from the audio source
- Turn off the internal speakers of your audio sound source. Contact the manufacturer of the audio sound source, such as your TV, for support.
No communication between the headphones and docking station
- Make sure that the AC adapter is connected to the docking station.
- Make sure the headphone batteries are charged.
- Make sure that the Power/Pairing indicator on the headphones and Pairing indicator on the docking station are on. If they are lit solidly blue, a communication link has been successfully established between the system. If they are blinking on one or both devices, see “Turning on and pairing the system” on page 15.
Cannot pair the headphones
- Shorten the distance between the docking station and your headphones.
- Make sure that the docking station is in pairing mode. Press and hold the pairing button for five seconds to re-enter pairing mode.
- Turn on the docking station, then place the headphones onto the station. They will enter autopairing mode (this may take 2-20 seconds).
Tip: If the power indicators on the headphones and docking station continue to blink after 20 seconds, they are no longer paired to each other. If this happens, follow these steps:
- Make sure that the headphones and docking station are within range of each other (ideally in the same room).
- Turn off the headphones and the docking station.
- Turn on both the headphones and the docking station. The lights will initially blink, then they light solid blue when connected.
