Do not use any SIYI system to operate your aircraft/vehicle/model at places with
intensive crowd (a square, a park), or at places with many obstructions (a street, a parking
lot), or in fields with strong magnetic or interference (an electricity plant, a radar station,
railways), or in any other fields where an irregular flight/operation may cause property loss
or human injuries.
Do not hold or cover the ground unit antenna or obstruct its transmission by any means
in a flight or in an operation.
Never point the ground unit antenna’s top ends straightly to your aircraft/vehicle while
it is working, they are the weakest parts for transmission.
Do not start your aircraft/vehicle/model when you are tired, drunk, in sickness or in
any circumstances you are not feeling good.
Do not fly an aircraft/model when it is rainy, windy or at night.
Do not power off the ground unit while your aircraft’s/vehicle’s/model’s engines and
motors are still working.
Please always try to operate your aircraft/vehicle/model within sight range.
Before a flight, please return to the starting menu on the ground unit.
Do not forget to check battery level of the ground unit and the air unit before starting
your aircraft/vehicle/model.
Always power off your aircraft/vehicle/model first, HM30 ground unit the second.

HM30 User Manual V1.0

Before configuring any settings on the ground unit, make sure your
aircraft’s/vehicle’s/model’s engines are powered off and their motor wires are disconnected,
in case of a sudden switch-on.
When you start your aircraft/vehicle for the first time, make sure that the fail-safe
settings on your ground unit is activated.
Always switch on the ground unit first and hold the throttle joystick on your remote
controller at zero output position, then power on your aircraft/vehicle/model.
Battery
HM30 ground unit is compatible the movie-industry-level NP-F550/F570/F950
series high capacity chargeable li-ion battery. Please do read the precautions before
using the battery with HM30 and charging the battery through HM30.
Please power off the HM30 ground unit before charging. The ground unit does not
allow charging while it is working.
Stop charging immediately if you found the charger damaged, broken or overheat.
Stop charging immediately if there was a peculiar smell, smokes or leaks from the
battery. In such cases you shall sent the product back to your dealer for after-sales service.
Do not charge the ground unit when its temperature is over 60℃.

1 INTRODUCTION
1.1 Product Features
30KM 1080P Full HD Image Transmission
HM30 applies SIYI’s brand new and cutting edge high-definition image transmission
technology with the ability to transmit 1080p 60fps video stream at *150ms low
latency. The technology comes with a smart feature to adapt its transmission to
better frequency bands, which means it always goes to work on the band with least
interference. With the standard omni directional antennas, HM30’s effective range
can reach up to 15 kilometers. With the long-range antennas, the range can be up
to 30 kilometers with full HD image transmission, real-time telemetry, and stable
control.
*The 150ms latency is an average result measured by using SIYI standard IP camera under the
following conditions:
H.265 format, 720p @ 30 fps, displayed in QGC v4.1 (low-latency mode): end-to-end latency is
between 130 and 180ms.
H.265 format, 1080p @ 30 fps, displayed in QGC v4.1 (low-latency mode): end-to-end latency is
between 180 and 250ms.
SIYI will release a new 1080p @ 60fps camera to effectively lower latency even more.
OSD Telemetry Display
Working with HM30, SIYI FPV app supports Mavlink telemetry overlayed with OSD
display. The OSD display information can be customized. FPV OSD with full HD
image will bring you endless fun.

HM30 User Manual V1.0

Network Relay, Dual Remote Control
HM30 will support Dual RC function, under which two ground units can bind to one
air unit to control flight and payloads at the same time. RC Relay function expands
the communication range for HM30.
*The features are in development and will come soon.
OLED Touchscreen Display and Configuration
The OLED touchscreen on HM30 ground unit displays its working status in real-
time and supports fast parameter configuration. Much more convenience for
outdoor flights!
Quick Release Battery, PD Fast Charging
Power supply to HM30 ground unit uses fast-release structure design for popular
battery models such as NP-F550/570/950 series. Max 30W PD fast charging can
be used to charge the battery through the transmitter.
You can use a 7 to 16.8 V external power for HM30 ground unit through its XT30
connector.
