experience. Equipped with PLL technology for optimal reception of the signal.

circuit for charging the batteries inside the headphone and auto-tuning for
the audio signal. Suitable for use with TV, CD, PC, MP3, RADIO, etc.
How to begin:
Before the wireless headphones can be used the following has to be done first.
Step 1:
Open the battery compartment on the right side to insert the rechargeable
batteries. Make sure the positive (+) and negative (-) poles are correctly
aligned.
Note: the right side of the headphone is marked with R in the headband and also recognizable as the shell with the power button.
Step 2:
Close the battery compartment after inserting the rechargeable batteries.
Step 3:
Insert the antenna into the antenna socket of the transmitter.
Step 4:
Connect the audio cable of the transmitter, fitted with a 3.5 mm jack plug, to
the headphones (audio) output of an audio providing appliance, like TV, audio
equipment, PC, etc.
Step 5:
Connect the plug on the AC/DC mains adapter cable to the DC IN socket at the
back of the transmitter. Then plug the adapter into a wall outlet.
Note: the power LED will not light up if the receiver is not receiving an
audio signal.
Step 6:
Before using the headphones, the batteries need to be charged. Take the
charging cable with the 2.5 mm power jack and plug it into the recharging
socket of the right shell of the headphones.
Note: Leave the headphones to charge for 24 hours before first use. The
second and subsequent charges take about 10 hours.
The red charge LED will light up indicating that charging is in progress.
Operation:
Switch on the audio-providing appliance and adjust its volume to roughly a
quarter of the maximum setting. The transmitter will switch on automatically.
When the audio appliance is switched off the transmitter will automatically
switch off after 4~5 minutes.
Note: If the volume output is too low the transmitter will switch off or
switch to standby mode and the SIGNAL/POWER LED will not light up. It is not
possible to charge and listen at the same time.
Charging has priority.
Step 1:
Switch on the headphones and the POWER LED will light up.
Do not turn the volume to maximum when switching on the headphones.
Step 2:
Select a channel with the channel switch at the back of the transmitter.
Adjust the headphone’s reception by pressing the AUTO TUNE button at the left
shell of the headphones.
Note : if the sound is poor, change to a different channel on the transmitter and press the AUTO TUNE button once more.
Note: When using the headphones at a maximum volume level, the batteries will run empty in a shorter time. It will also increase the possibility of hearing noise due to the wireless connection. Therefore it is recommended to increase the volume level of the audio providing appliance and decrease the volume level of the headphones. This will improve the performance of the wireless headphones.
