the product, and the leakage protector, overcurrent protector, etc. meet the
requirements of the load;

Do not use power cords with damaged insulation, and do not connect power cords to
other wires;

The lamp uses strong wind cooling, which is easy to accumulate dust. It must be cleaned
once a month, especially the cooling air vent, otherwise it will be blocked by the
accumulated dust, resulting in poor heat dissipation and abnormality of the lamp.

When installing the lamp, the fixing screws must be tightened with safety ropes, and
checked regularly;

When installing and positioning the lamp, keep the minimum distance between any
point on the surface of the lamp and any flammable and explosive materials at 10
meters and the distance from the irradiated object is 2.5 meters. Please do not install
the lamp directly on the surface of flammable substances;

The continuous working time of the lamp is not recommended to exceed 10 hours, and
the interval between continuous startup of the lamp should not be less than 10 minutes,
otherwise it will not trigger normally due to overheating protection of the lamp;

The closing time of the on-off valve should not exceed 5 minutes. If you need to close
the light for a long time, you should use the console (lamp control channel) to turn off
the lamp;

In order to ensure that multiple lights better comply with the scene effect, the light
should not always be in the current scene, that is, start the next scene action, it is best
not to exceed 3 minutes to ensure that multiple fixtures can run synchronously;

During use, if the lamp is abnormal, stop using the lamp in time to prevent other faults
from being induced.
2. RDM Precautions for Use
RDM is an extended version of the DMX512-A protocol. It is a Remote Device
Management protocol. The traditional DMX512 protocol communication is one-way
communication. The protocol is based on the RS-485 bus. RS-485 is a time-sharing
multipoint and half-duplex protocol. Only one port is allowed to be output by the host at the
same time, so pay attention to the following points when using RDM:

To use a console or host device that supports the RDM protocol host;

To use a two-way signal amplifier, the traditional unidirectional signal amplifier is not
applicable to the RDM protocol, because the RMD protocol requires feedback data, and
the use of a unidirectional amplifier will block the returned data, resulting in the failure
to search for the lamps;

All lamps must be set to DMX mode to ensure that there is only one host on the signal
line;

A 120 ohm impedance matching resistor must be inserted between terminals 2 and 3 of
the terminal plug. When the signal line is relatively long, reducing the signal reflection
will let a differential signal to be more stable, which is beneficial to the quality of
communication;

When lamps are under DMX control, but cannot be searched by RDM, first check the
