2. Regulatory Conformance Information

The module radio transmitter operations must be compliant with some regulatory
requirements in terms of frequency bands and emitted power, as detailed below.

2.1. 169 MHz band Requirements

The “ERC recommendation 70-03 Annex 2” describes the 169 MHz license free band for
meter reading, in terms of bandwidth, maximum power, duty cycle and channel spacing. It
gives the following limitations:

ERC recommendation 70-03

Band Frequency band

(MHz)

Maximum

radiated power

(mW)

Channel spacing

(kHz)

Duty cycle

(%)

2b 169.4 – 169.475 500 Max 50 khz 10

These bands are free to use but the module and the user must respect some limitations. Most
of these restrictions are integrated in the conception of the module, except the duty cycle. For
example, the 2b band is limited to a 10% duty cycle. This means that each module is limited
to a total transmit time of 6 minutes per hour. It is the responsibility of the user to respect the
duty cycle.

National Restrictions for non specific SR devices Annex 2 band B:

Country Restriction Reason/Remark
Band F

Austria Not implemented Planned
Belgium No info
Bulgaria Not implemented The band is used for national security needs
Croatia Limited implementation Individual licence required
Cyprus Cyprus has implemented Decision 2005/928/EC
Georgia Not implemented

2.2. Other Regulatory Requirements

Furthermore, the module complies with the ETSI 300 220-2 v2.4.1 standards (specific for
SRD).

ME70-169 also complies which EN 13757-4 standards (Wireless M-Bus Part4).
Finally, the module complies with the new European Directive 2002/95/EC concerning the

Restrictive Usage of Hazardous Substances (RoHS).
