5. Operation Manuals
1) Connection Method of Transmitter
Connect with mobile phone: insert H-TX
into HDMI port of C2H, and connect C2H
through Type-C data cable of soft head and
Type-C port of mobile phone with DP output,
as shown in the figure. Attention: The tran
smitter’s antenna is on the side with Peak-
Do logo, which must be faced outside, as
shown in the left figure.
Connect with computer: H-TX trans-
mitter is directly inserted into HDMI
output port of computer.
Due the characteristics of the 60GHz millimeter wave, the antennas of trans-
mitter and receiver need to have a correct alignment, smaller than 60 degrees.
A smaller alignment angle results in a stronger signal. As shown in the foll-
owing figure.
Up to 5 Meters

charger
❌

connection between transmi-
tter and computer)
Connect while charging: The transmitter
can be powered by the mobile phone. When
projecting for a long duration, or the
battery of the mobile phone is insufficient,
it can be charged while projecting according
to the connection method as shown in the
left figure.

Connection using an USB auxiliary power
supply cable: the HDMI port power supply of
some laptops or computers (especially old
machines) is not enough to supply the
working current of the transmitter. In this
case, a short USB-A to Type-C power supply
cable can be used to provide sufficient
working current for the transmitter.
Indicator lights of transmitter and receiver:
After the power is plugged in, the indicator lights will display the connection
status in red, blue and green, and the status of indicator lights of transmitter
and receiver will be synchronized.
Long distance projection via computer: for
long distance projection (for example: 5m),
the antenna of transmitter and receiver
should be within the direction angle of 60° to
achieve the best signal reception. In
this circumstance a 360° HDMI adapter can
be used to adjust the antenna direction of
transmitter, as shown in the left figure.
Red: power on Blue: Searching for signal Green: connection successful
If the transmitter or receiver continues to display blue light, it means that
the device is not connected. Please press the reset key of the transmitter
once, wait for 5-6 seconds to establish connection. If the connection still
cannot be established, please reset the device. Method: press and hold the
reset key of the transmitter and receiver for 10 seconds simultaneously. After
the indicator is off, release the reset key, and the device will reconnect.

2) Setup of receiving end:
HDMI
HDMI transmitter Type-C to HDMI
Type-C
Note:
When pairing, make sure that the transmitting end and the receiving end
are unobstructed and is within the visible range of 5 meters.
After successful pairing, there is no need for a second setup even if power
supply has turned off, unless a different transmitter or receiver is replaced.
The sending end is composed of HDMI transmitter (H-TX) and type-c to HDMI
(C2H). When the mobile phone needs to cast on the big screen,
insert the H-TX into the HDMI bus of C2H according to the above figure. When
laptop, Nintendo Switch, play station or camera needs to cast on the big
screen, insert the H-TX into the HDMI-out bus of the device (if the power
supply of the HDMI-out port of the device is insufflcient, use the USB
auxiliary power supply cable).

The side where the indicator light of the receiver is located is the front of the
antenna. Please ensure that this side is visible to the signal transmitting side
of the transmitter (Fig. (3) B: antenna position), and try to avoid obstacles
between the transmitter and receiver. The receiver should not be installed
on the back of the display device, otherwise it may block the signal and
affect the signal. It is recommended to clip the receiver to the outer edge of
the TV frame with an attached bracket.
Caution:
When using external power supply, please confirm that the power output is
DC 5V/2A+ power supply. Otherwise the equipment may be damaged!
The optimal working distance of this product is within 5 meters. The signal
transmission requires the receiving and transmitting antenna to be aligned
within 60 degrees without shielding. Adjust the placement position to reach
the optimum experience.
The receiver USB port need to connect the supplied USB charger power
adapter. If use the third party power supply, make sure the output voltage of
the supply port is DC 5V and the current is at least 2A.
