To avoid fire hazard, use only the power cord specified for this product.
Avoid Electric Overload
To avoid electric shock or fire hazard, do not apply a voltage to a terminal that is specified
beyond the range.
Ground the Product
This product is grounded through the grounding conductor of the power cord. In case no
ground is available at the power outlet, it is recommended to provide a separate grounding
path to the instrument by connecting wire between the instrument ground terminal and an
RedwoodComm Co., Ltd. 5/42

earth ground to avoid electric shock or instrument damage. Before making connections to the
input or output terminals of the product, ensure that the product is properly grounded.
Do Not Operate Without Covers
To avoid electric shock or product damage, do not operate this product with protective covers
removed.
Do Not Operate in Wet/Damp Conditions
To avoid injury or fire hazard, do not operate this product in wet or damp conditions.
Do not use in a manner not specified by the manufacturer
1.2.2 Product Damage Precautions
Use Proper Power Source
Do not operate this product from a power source that applies more than the voltage specified.
Main supply voltage fluctuations not to exceed ± 10% of the nominal voltage.
Provided Proper Ventilation
To prevent product overheating, provide proper ventilation.
Do Not Operate With Suspected Failures
If there is damage to this product, have it inspected by qualified service personnel.
Environmental Conditions
Refrain from using this equipment in a place subject to much vibration, direct sunlight,
outdoor and where the flat is not level. Also, do not use it where the ambient temperature is
outside 5 °C to 40 °C, and altitude is more than 2000m. The maximum relative humidity is
80% for temperatures up to 31 °C decreasing linearity to 50% relative humidity at 40 °C. Over
voltage Installation Category II for mains supply. Pollution Degree 2

1.3 General Information
ETI (or MDI) files describe the characteristics of a signal suitable for transporting a full DAB
Ensemble (or DRM Multiplex), where the ETI comprises a number of subchannels and a formatted
Fast Information Channel (FIC) between a DAB Ensemble provider and a transmission network
provider, and the MDI comprises a number of streams and a formatted Service Description Channel
(SDC) between a DRM Multiplex provider and a transmission network provider. It means that if a
specific broadcasting station’s T-DMB/DAB (or DRM) signal is recorded as an ETI (or MDI) file, the
recorded file contains all the information about the station.
Using the RWC2010M’s ETI/MDI player function with these files, specific broadcasting stations’
T-DMB/DAB signals or DRM signals can be easily regenerated in labs. The RWC2010M also provides
analog functions as AM/FM transmission and audio analyzer. It also provides RDS functionality as a
way to play pre-encoded RDS files.
It can be operated stand-alone, and also can be controlled and played with the RWC2010x PC
application. The RWC2010x PC application provides various control and measurement functions such
as file handling, AM/FM setting, remote controlling and gathering audio measurement data from
RWC2010M. Audio measurement data includes SINAD, SNR, THD, waveform and spectrum.
