MU-1-R Certificat de conformité

MU-1-R

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.

R&TTE Directive article	Test category	Harmonized standard
Articles 3.1 (a)	Protection of the health and the safety	EN60950, EN 50371
Articles 3.1 (b)	EMC	EN 301 489
Articles 3.2	Effective use of the spectrum	EN 300 220

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.

Note: The MU-1-R is intended to be used in all EU and EFTA countries.
There may be restrictions on the use of voice and audio applications in the following countries; FI, FR, HU, IT, LU, LI, CH.

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		Power	Channel Spacing	Duty cycle (%)*
f	433.050 - 434.790 MHz	10 mW e.r.p.	No channel spacing	Below 10%
f1	433.050 - 434.790 MHz	1 mW e.r.p. -13 dBm/10 kHz for wide band channels	No channel spacing	No duty cycle restriction
f2	434.040 - 434.790 MHz	10 mW e.r.p.	Up to 25 kHz	No duty cycle restriction
* Duty cycle is the longest time when transmission is “on” in a single carrier frequency within one hour, expressed as a percentage.

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.

ERC/REC 70-03 Annex 1		MU-1-R
Frequency Band		Usable channels	Frequency alignment range	Spacing
f	433.050 to 434.790 MHz	0 to 63	433.200 to 434.755 MHz	25 kHz
f2	434.040 to 434.790 MHz	34 to 63	434.050 to 434.755 MHz	25 kHz

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.)
