| Regulatory compliance of the MU-2-R |
The MU-2-R is made for embedding in other equipment.
(Products incorporating the MU-2-R are henceforward referred to as final products.)
The European regulation applicable to the MU-2-R is the R&TTE Directive 1999/5/EC.
MU-2-R meets the following requirements of the R&TTE Directive.
| R&TTE Directive article |
Test category |
Harmonized standard |
| Articles 3.1 (a) |
Protection of health and safety |
EN 60950, 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-2-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-2-R has received the CE mark.
Note: The MU-2-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-2-R |
1. Duty cycle
The MU-2-R is intended to be used in the 433.05-434.790 MHz band in the ERC/REC 70-03 Annex 1, Non-Specific Short Range Devices shown in the table 1 below.
The transmitting time and downtime of the MU-2-R and selection of the frequency channel are controlled by the final product in which the MU-2-R is embedded. The final product in which the MU-2-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.

Duty cycle
(%)* |
| 433.050-434.790 Hz |
10 mW e.r.p. |
No channel spacing |
Below 10% |
| 433.050-434.790 Hz |
1 mW e.r.p.,
-13 dBm/10 kHz for wide band channels |
No channel spacing |
No duty cycle restriction |
| 434.040-434.790 Hz |
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.

2. Antenna
The radio and EMC parameters of the MU-2-R radio modem have undergone conformity evaluation with the lead antenna model ANT-LEA-01 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-2-R radio modem cannot be used for the conformity assessment of the final product.
3. Supply voltage
The MU-2-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-2-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-2-R should be exposed.
5. Documentation
In the documentation for the conformity assessment of the final product, state clearly that the MU-2-R radio modem is embedded in the system. (The MU-2-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.
