QUICK START DIAGRAM
1.Transmitter plugs into the Guitar (you instruments),
the receiver plugs into the effects pedal, AMP, Audio,
etc.
2.Turn on the Transmitter and the receiver, the A B C D
LED will indicate how much volume of the battery,
each LED means about 25% of the battery volume.
for example,if A B C D LED all light on,it means
about 100% full volume left,and the like if only A LED
lights on means about 25% of the battery volume left.
if the A LED turn red and flashing,it means the battery

Q & A
Four channels
The O2 wireless guitar system has four different
channels, and can use up to 4 pair of systems at the
same time. When your band plays for guitar, bass,
keyboard and other instruments, O2 can set up
different channels for them to prevent signal
interference. When there is only one player, the
different channel function can also be used for him/her
to prevent interferences from different frequency
bands of routers or other WIFI devices. Generally we
recommend to use Channel A
Portable Plug-and- Play design
O2 wireless system uses a portable design; both the
receiver and the receiver are plug-and-play design. It
is very convenient for fast switching among guitar,
bass, amplifiers, effect pedal and other audio
equipments. It provides more flexibility in adjusting the
equipments.
One Transmitter and multiple Receivers
When using a transmitter, you can use multiple
receivers. For example, if you want to connect a guitar

12
to two amplifiers or connect to effect pedal and pedal
tuner, you need just use multiple receivers with setting
up to be the same channel.
O2 Receiver
Since O2 is the 2.4 GHz wireless system, please
avoid putting the receiver close to other signal emitting
devices. It is recommended that your O2 receiver
keep a distance of more than 3 meters from the other
2.4 GHz transmitter and WIFI router.
Auto sleep/wake up mode
The auto sleep/wake up mode will start when over
10 seconds there is still on signal input,it make you
more silent when you stop playing,meanwhile, it
also help you to save the battery volume.
Power charge
There is a “Y” shape cable in the package. It can
charge the transmitter and receiver at the same time.
The voltage output is 5V. The channel A LED never
turn to red for normal use. Red A LED light flashing
means low battery which requires immediate power
charge.

13
When in charging,the A B C D LED will flash orderly,
different LED flash indicate different battery volume.
you can judge according to the A B C D,for example
the A B LEDs are in solid green,the C LED is flashing,
it indicate the A B part is charged full and now is
charging C,in another words 50% battery volume is
charged,when battery charged full, the A B C D LED
will become solid green.
Channe LED Flashing after making pairs finished
The channel LED light flashing indicates there is signal
interference. Please switch to another channel, turn
off or stay away from other 2.4GHZ WIFI, to make
sure the U2 transmitter and receiver antennae be in
the signal receiving range.
Antennae angle
The rear end of O2 is the antenna, which can be used
at about an angel of 180°. The front signal of the
transmitter and the receiver is the strongest. Please
try to keep the front to face each other during using.
Do not block the antenna with your hand or other
items, and keep the signal within the receiving range
of the antenna.
When confront with interferrence from other devices

14
or need more distance for using, you can change the
antenna's angle and adjust it to be the best condition.
Supportive pickup and musical instrument
O2 wireless system can works for passive guitar
and active pickup, piezoelectric acoustic guitar pickup,
piezoelectric violin pickup.
Transmitter is better to connect to the instrument.
Please avoidconnecting it to distortion effect pedal
or high power output interface which may incur the
timbre distortion.
USB port
USB only works for charging function, does not
support firmware upgrade.
