Type approval
The TX1 module is type approved to European harmonised standard ETSI EN 300 220-3 for UK use
within the following categories:
(a) General applications in the band 173.2-173.35MHz but excluding 173.225MHz.
(b) Industrial/commercial applications at the same frequencies as category (a).
(c) Fixed/in-building alarm applications at 173.225MHz.
(d) Medical/biological applications (including airborne use for the tracking of birds) in the band 173.7-
174.0MHz.
REQUIREMENTS FOR CONFORMANCE TO ETSI EN 300 220-3:
1. Transmitted ERP (effective radiated power) must not exceed the limit of 1mW (0dBm) for category
(a) or 10mW (+10dBm) for categories (b), (c) and (d). Equipment in category (a) must include a 10dB
attenuator between the TX1 RF output pin and the antenna or feed, as specified on page 7 of this
leaflet.
2. Any type of antenna system may be employed provided that the applicable ERP limit is not exceeded
- i.e. transmitting antenna structures which exhibit ERP gain (such as yagis) are not permitted. See
pages 10-13 of this leaflet for details of suitable antennas.
3. The module must not be modified or used outside its specification limits.
4. The module may only be used to transmit digital or digitised data. Speech and/or music are not
permitted.
Breaching any of these conditions will invalidate type approval.
