Switching the headset on
To switch the headset on:
Press and hold the Play/Pause button for 2 seconds.
An ascending confirmation beep is heard in the headset and the LED indicates the current operating mode. Flashing in blue indicates that the battery charge status is OK; flashing in red indicates a low
battery (see page 6).
The LED flashes several times every second:
The headset is paired to one or several Bluetooth devices and tries to connect to one of these devices.
The LED flashes slowly (once every second):
The headset is paired to one or several Bluetooth devices. However, there is no current connection because the
Bluetooth device is switched off or out of range.
The LED flashes once every 3 seconds:
The headset is paired to one or several Bluetooth devices. However, there is neither an audio transmission nor an active call.
The LED is glowing slowly every 4 seconds:
The headset is paired to one or several Bluetooth devices, a sound file is received via A2DP and played back or
paused.
The LED flashes once every second:
The headset is paired to one or several Bluetooth devices and there is currently an active call.
If you switch on the headset and keep the Play/Pause button pressed for 5 seconds, the headset will go into pairing mode (see ?Pairing the headset? on page 9).
The LED flashes alternatingly in red and blue for up to 60 seconds:
The headset is not yet paired to any Bluetooth device. Pair it as described under ?Pairing the headset? on page 9.

When device is in pairing mode (device on, long press "talk" button until LED is steady blue), long press the "up" button until the LED blinks twice.
Then search it on the second phone and pair it.
Turn HS off, then on.

The "pair" the remote with your system:

1.PRESS AND HOLD the f button on the remote UNTIL the transmit LED lights solid (approximately 10 seconds)
2.PRESS AND HOLD the remote start button (circle arrow) UNTIL the LED blinks 3 times and the amber transmit LED lights up. Your remote is now ready to pair.
3.. Turn the key to the on position
4.Within 5 seconds PRESS AND RELEASE the control button on the antenna.
5. Within 5 seconds PRESS AND HOLD the control button. The status LED will flash one time and the siren will chirp to confirm that the system is ready for remote pairing.
6. Press lock button on remote. System will respond with chirp toconfirm pairing.

I use these and the previous model without any issues.

1. They must be plugged into the wall socket. It's okay to use an extension cord between the adapter and the wall, but never a surge suppressor or UPS
2. The master need to be connected to you router
3. To test your connection do the following
-Plug the master into the wall at the router location
-Plug the slave into the outlet where the computer will be
-Press and hold the setup button on the slave unit only for 3-5 seconds
The leds on the slave will flash for a second or two and then turn solid.
The number of solid lights you see tell you what your connection speed will be 0-no connection, 1-<10MB , 2=-10-30MB, 3->30MB.

I always unplug the ethernet cables from the adapter when testing, but I don't know if that is necessary.

I have never gotten less then 2 leds in my house, but it's new.

Check lamp, Ballast and the Air filters

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.

Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.

Figure 2
3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.

Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.

Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.

Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.

Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.

Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.
