Regulatory compliance of the
MU-1-R |
The MU-1-R is made for embedding
in other equipment.
(Products incorporating the
MU-1-R are henceforward referred
to as final products.)
The European regulation
applicable to the MU-1-R is the
R&TTE Directive 1999/5/EC.
MU-1-R meets the following
requirements of the R&TTE
Directive.

The conformity assessment for
the MU-1-R was completed in
accordance with the R&TTE
Directive Annex III procedure,
and the EC Declaration of
Conformity is attached to this
manual. The MU-1-R has received
the CE mark.

Cautions regarding regulatory
compliance when embedding the
MU-1-R |
1. Duty cycle and frequency
channel
The transmitting time and
downtime of the MU-1-R, and
selection of the frequency
channel are controlled by the
final product in which the
MU-1-R is embedded. The final
product in which the MU-1-R is
used must be designed so that
the frequency band and duty
cycle conform to the radio
regulations of the countries
where it is to be used.
The MU-1-R is designed to be
used in the frequency bands f
and f2 in the ERC/REC 70-03
(Edition of October 2005) Annex
1, Non-Specific Short Range
Devices shown in the table below
and from 433.050 to 434.790 MHz.
Specifically, the MU-1-R is
channelized in 25 kHz steps and
has channels 0 to 63 in the
433.050 to 434.790 MHz band.
(Refer to the table in 2.3
Usable Channels). The nominal RF
output of the MU-1-R is fixed at
10 mW.

Frequency band f in Annex 1
above is harmonized. Based on
the R&TTE Directive, radio
equipment that has these
frequencies and technical
characteristics can be
introduced on the market without
restriction within the EC as
Class 1 radio equipment. Radio
equipment that meets the
criteria outside of f for
frequencies and technical
characteristics that are not
harmonized is defined as Class 2
radio equipment, and there are
still some countries that
implement restrictions on its
sale and use. When using Class 2
radio equipment, it is necessary
to notify the radio regulatory
authority in the country where
it will be used, and to attach a
class identifier (alert symbol)
stating that there are countries
that limit the use of the
product.
Specifically if the final
product equipped with the MU-1-R
is operated within 433.050 to
434.790 MHz with a duty cycle of
10% or less, the final product
is classified as Class 1 radio
equipment.
Otherwise, if for example the
final product uses the MU-1-R at
a duty cycle higher than 10%, it
is classified as Class 2 radio
equipment, the radio regulatory
authority must be notified, and
the product must be labeled with
an alert symbol.
By frequency channel used
(1) When using the MU-1-R at
duty cycles of less than 10%,
all channels (0 to 63) can be
used.
(2) When using the MU-1-R at
duty cycles higher than 10% (for
continuous transmission and so
on), only channels 34 to 63
should be used. In this case,
the final product is classified
as Class 2 radio equipment.
The following table show the
programmable frequency channel
range of the MU-1-R and its
relationship with the range
specified in ERC/REC 70-03 Annex
1.

2. Antenna
The radio and EMC parameters of
the MU-1-R radio modem have
undergone conformity evaluation
with the lead antenna model
ANT-LEA-01-R provided as a
standard accessory. Other
antennas cannot be used. If
another antenna is used, the
results of the radio conformity
assessment obtained by the
MU-1-R radio modem cannot be
used for the conformity
assessment of the final product.
3. Supply voltage
The MU-1-R radio modem should be
used within the specified 3V to
5V voltage range.
4. Enclosure
To fulfill the requirements of
EMC and safety requirements, the
MU-1-R should be mounted on the
circuit board of the final
product and must be enclosed in
the case of the final product.
No surface of the MU-1 should be
exposed.
5. Documentation
In the documentation for the
conformity assessment of the
final product, state clearly
that the MU-1-R radio modem is
embedded in the system. (The
MU-1-R radio modem has received
the CE mark.)
6. Exemption clause
Circuit Design, Inc. does not
guarantee the accuracy of the
information above.
Directives, technical standards,
principles of operation and the
like are interpreted differently
by the authorities in each
country. The directives of the
EU and of each country also
differ. In case of doubt or
uncertainty, we recommend that
you check with the authorities
or official certification
organizations of the relevant
countries |
