Operating Instruction
Step 1:
Plug the included 5V AC/DC power supply into the DC jack at the rear
of the transmitter, then plug the other end of the power supply into a
wall outlet.
Step 2:
Turn on your audio source(e.g. TV set, HI-FI system, MP3 or iPod),
please set the television, audio amplifier or DVD/ CD player
headphone volume level at approximately half way (50%).
Step 3:
Connect the transmitter with TV/Phone/Computer through the Optical
Input or Aux Input by provided optical cable or 3.5mm audio/RCA
cables. Switch on the transmitter to channel A or B position, RED led
on. When audio device connected and there is with music, the
transmitter BLUE led on. If audio device was unconnected or without
music, 3-6 minutes later, the transmitter will auto turn off.
Like, you could connect the transmitter to a TV in three different
methods.
Method 1: for Connection Through TV Earphone Jack
The TV headphone jack corresponds to the 3.5mm IN socket on the
backside of the transmitter. Connect one end of the 1.5m audio cable
(3.5mm) to the transmitter socket and the other end to the headphone
jack on TV.
02

Now, you can hear sound through headphones, and if not, please
make sure to set your TV speaker to “Headset”.
Method 2: for Connection Through TV RCA sockets
Please connect the included RCA 3.5mm adapter cable to the RCA
Audio Out jack on TV. And connect the included 3.5mm cable to the
RCA adapter cable and the other end of the 3.5mm cable into the
Audio In jack on the backside of the transmitter.
Now, you can hear through headphones, and if not,
A.Make sure the connected sockets are the white/red sockets labeled
“AuDIo ouT”, and other white/red sockets are incorrect.
B.Make sure to set your TV speaker to “External Speaker”.
Methods 3: for Connection Through TV Optical Output
Please connect one end of the included optical digital cable to the
optical output socket on TV and the other end to the optical input
socket on the backside of the transmitter.
03

Now, you can hear sound through headphones, and if not:
A.Make sure to set your TV speaker to “External speakers”.
B.Make sure to set the audio format to “PSC” or turn off “Dolby
Atmos/DTS” (This is important.)
C.Make sure the audio source sampling rate is not more than 16bit /
48KHz.
Notice: when using optical output, please remove any cable from the
3.5mm AUX jack.
Step 4:
Turn on the headphone and make sure the RED signal/power led is
on. If necessary, push the volume control to a medium level. Adjust
the headphone reception by pressing the tune button once. The LED
will turn GREEN, once received audio signal.
Step 5:
When you’re not using the headphone & transmitter, please turn them off.
Wired headphone: Switch the headphone Power On/Off button to
turn off the headphone. Plug in 3.5mm audio cable to the headphone
audio IN, and connect the opposite end to your audio device, like MP3
, phones etc. Then you can use the headphone as a wired
headphone. However, in this mode, you won't be able to adjust the
volume by using the switch key.

Headphone Charging: You can charge the headphone with a 5V/1A
USB power supply.
The total charge lasts approximately 2.5 hours.
When start charging, the LED light will keep blue, when the charging
is finished, the light will turn off.
Warning:
1.If the volume is too low, the transmitter switches off after 3-6
minutes of use. This is to comply with the current legislation on
reducing the amount of radio emissions in the environment. Therefore,
to ensure that this function is not accidentally triggered, we suggest
that you set the television, audio amplifier or DVD/ CD player
headphone volume level at approximately half way (50%).
2.On some newer TV sets, it may be necessary to increase the output
level of the headphone jack or the Audio Out jacks. Check your TV’s
owner manual for details.
3.Please make sure all connections are completely successful.

awareness can be facilitated by the use of a product label directing
users to specific user awareness information. Your Retekess radio has
a RF Exposure Product Label. Also, your Retekess user manual, or
separate safety booklet includes information and operating instructions
required to control your RF exposure and to satisfy compliance
requirements.
