Instruction Manual of SI03 draft
Vlfireless Headphone
Product Description
The wireless headphones system consists of a transmitter, a compact headphone with an integrated
amplifying system and a plug—in power supply unit.
The transmitter transforms the audio signal into a radio signal and emits it by means of an antenna.
The antenna integrated in the headphone receives this radio signal, transforms it back into an audio
signal and the Integrated amplifier makes the signal audible in the headphones With the supplied
adapters lhe system can be connected to 35mm or 6.3mm stereo headphones lack socket of various
signal sources.
The transmitter and the headphone have separate OnIOfi switch,
With the volume control button on the headphone, the volume can be adjusted easily without touchlng
the audio source
System included:
- Transmitter
— Headphone
- Adapter 3.5mm jack plug to 5.3mm plug.

a. Volume cont7o|
Wlth this control you can adjust the playback volume.
Tum clockwise to increase the volume-tum counter clockwise to reduce the volume.
9. Battery compartment
Place the batteries for the headphone in here.
Placing/changing of batteries
Tmnsmitter: (operated by 12V DC adapter)
Make sure that the power supply unit of the transmitter is not plugged in a wall outlet and that the onlofi
button (1 ) of the transmitter is “OFF".
Headphone:
Press on the middle part of the cover of the battery compartment (9) to open the lock ofthe oover.
Open the cover of the battery chamber by sliding the cover downwards.
Place two new AAA batteries into the battery compartment, observing the correct pole direction. You
can see the correct pole direction from the illustration in the battery compartment.
Replace the cover of the battery chamber.
Tip:
Use alkaline batteries for a longer service life. Alternatively you can also use rechargeable storage
batteries; however due to the lower capacity the tlrne of operation will be much shorter. Only use
leak-proof batteries.
Changing the batteries
Changing the batteries becomes necessary when the quality deteriorates (noise distortion, limited range
etc) Change both batteries (DO NOT MIX NEW AND USED BATTERlES) at the same time.
Do not leave batteries unattended. They might be swallowed by children or pets. if batteries have
been swallowed see a doctor immediately!
Leaking of damaged batteries may cause cauten‘zations if they touch the skin. therefore use protective
gloves.
Make sure that the batteries are not shorted clrouited.
Never try to recharge non-rechargeable batteries. Do not throw batteries into the fire: danger of
explosion!
Take out used batteries at once; even ieak»proof batteries can con'ode, emitting chemical substances
that might be hazardous to your health or damage the battery compartment. If you do not use the unit
for a longer period of time. take the batteries out.
Placement of the transmitter
When choosing the location for installing the transmitter please take into consideration the system range.
the features of the room like and the location of the audio sources unit and the distance to the heating
system as the system must not be placed next to a heater.
Make sure that the transmitter or the headphone Is not shielded by metal object such as steel-reinforced
concrete walls. metal—coated mirrors, metal fumiture etc. There should not be any system with strong
electrical fields near the transmitter or headphone like such as cordless telephones. radio, and electric
motors. The radio transmission could be disturbed or the range reduced considerably.
Place the transmitter on a safe, horizontal base. Make sure to avoid direct sunlight, vibrations, dust
heat cold and humidity.
Installing the transmitter antenna
Screw the supplied antenna into the opening on the upper surface of the transmitter.
Connecting the transmitter
In order to avoid distortion or maladlustments that would damage the system. only connect audio plugs
to unit is with a headphones jack to the audio socket of the transmitter. Please observe the connecting
specifications in the technical data.
Make sure that the batteries are fresh enough or the power supply of the transmitter is not pluged in wait
outlet and that the Onlofi switch (1) of the transmitter is “OFF'.
Switch off your audio sources (ie. TV, MP3 player, etc)
Connect the audio connecting cable (3) of the transmitter to the socket of your audio source. Use the
correct adapter if necessary (not supplied).
Put the connecting plug of the power supply unit Into the socket (2) of the transmitter.
Plug the power supply unit inot a 120V150Hz wall outlet of the local mains The transmitter is now
ready for operation.
