normally on red light to normally on green light. After successful
upgrade, green light shall flash slowly for three times. Afterwards,
it shall become to off of green light and the red light shall be
normally on to further start the system.
II. Instruction for Code Matching and Frequency Switching
1. Code matching:
1>After TX and RX devices are turned on and started, hold the code
matching keys of TX and RX devices for about 4S to start code
matching. At this time, LED light of TX and RX shall flash quickly for
prompt. If RX is already connected with a TV , the TV will display OSD
prompt “WPS Processing...”in code matching is output from RX .
2> After code matching is completed, LED light returns to normal
flashing. If RX is already connected with a TV, the TV will display
prompts OSD. “WPS Succeed” is output in case of successful
code matching, and “WPS failed” in case of failed code matching.

2. Frequency switching:
When the network condition of current frequency is unsatisfactory,
a better frequency can be selected by manually switching.
The operation way is shown below:
1> Press the code matching key for short time at TX to start
the frequency switching operation. At this time, red light and green
light flash alternatively to prompt that the frequency is in switching.
After the frequency switching is completed, flashing light returns
to normal condition. The network shall be reconnected at this time.
2> When the network is in connected status and the images are
transmitted normally, the frequency switching operation can also
be started when the code matching key is pressed for short time
from RX. After frequency point switching is started successfully,
red lights and green lights shall flash quickly and alternatively.
In case of failure in start, the red light shall flash quickly to
prompt the abnormity.
III. Operation Instruction for LOG Collection
LOG collection is conducive to quick analysis of issues of device.

*The receiver OSD output is normal and the audio output is abnormal
after the transmitter and receiver are normally connected.
One USB flash disk with less than 32G capacity;
1. LOG collection preparation:
2. Format the USB flash disk as FAT32 format: Formatting way
is shown in the firmware upgrade instruction;
3. Turn on to start the transmitter and receiver devices.
4. After the transmitter and receiver devices are started,
if it is required to collect LOG file, connect the USB flash disk
to mini USB interface of the device via a USB cable.
At this time, the device shall automatically write LOG
information into USB flash disk.
5. To collect LOG file, please guarantee that the USB flash disk
and the equipment are connected for at least 1 minute.
6. After collection of LOG, pull off the USB flash disk.
Connect the USB flash disk to PC and browse files in the USB
flash disk. At this time, you can see some txt files with
MII_RX_log <LOG file of receiver> and MIX_TX_log <LOG file
of transmitter> as the prefix.
These are LOG files collected from the transmitter and receiver.
Digital serial number in the file number represents the number
of LOG file collected, such as MII_RX_log0.txt, MII_TX_log0.
